Validity and Renewal of ANSSI Cryptography Authorization

When ANSSI grants an authorization for cryptographic operations, it comes with a limited validity period. For operations that require explicit authorization, such as the transfer of cryptographic means within the EU or exports outside the EU, the certificate of authorization issued by ANSSI is valid for one year if no express decision is made within the given timeframe.

The renewal process must be initiated before the expiry of the certificate. ANSSI will review the completeness of the application within two months, and the decision is issued within four months. If ANSSI remains silent, implicit authorization is granted, which is again valid for a period of one year. This renewal ensures that your cryptographic operations remain compliant with the regulations established by Decree n°2007-663 and EU Regulation 2021/821, avoiding any legal or operational disruptions.

For further details on how to initiate a renewal or first-time application, refer to the official ANSSI process, ensuring all deadlines are respected for uninterrupted operations.

Legal Framework for Cryptographic Means: Key Requirements Under Decree No. 2007-663

Understanding the legal implications of Decree No. 2007-663 is crucial for any business engaged in cryptology-related operations, such as the import, export, or transfer of cryptographic products. This section outlines the legal framework governing declarations, authorizations, and specific cases for cryptographic means. Let’s delve into the essential points:

1. Formalities Under Chapters II and III of Decree No. 2007-663

Decree No. 2007-663 distinguishes between two regulatory regimes—declaration and authorization—depending on the nature of the cryptographic operation. These formalities aim to safeguard national security by ensuring cryptographic means are not misused.

Chapter II: Declaration Regime
This section requires businesses to notify the relevant authorities, particularly ANSSI, when cryptographic products are supplied, transferred, imported, or exported. For example, when transferring cryptographic software within the European Union, companies must submit a declaration to ANSSI. This formality ensures that the movement of cryptographic products adheres to ANSSI cryptography authorization protocols. The primary goal is to regulate the flow of cryptographic tools and prevent unauthorized or illegal uses.
Chapter III: Authorization Regime
Operations involving cryptographic means that pose higher security risks, especially when exporting to non-EU countries, require explicit authorization from ANSSI. The export of cryptographic products, such as encryption software, outside the European Union is subject to strict scrutiny. In these cases, companies must obtain ANSSI cryptography authorization, which evaluates potential risks before granting permission. Failure to secure this authorization could result in significant legal consequences, such as operational delays or penalties.

2. Request for Authorization or Renewal

If your operations involve cryptographic means that require prior approval, the Decree mandates that you apply for authorization or renewal. This is particularly relevant for:

Transfers within the EU: Even though the product remains within the European Union, if the cryptographic tool is sensitive, an authorization request must be submitted. This helps mitigate risks associated with misuse or unauthorized access to encrypted data.
Exports outside the EU: Exporting cryptographic means to non-EU countries is subject to even stricter controls. Businesses must renew their authorization periodically to ensure that all their ongoing operations remain legally compliant. This step is non-negotiable for companies dealing with dual-use items, as defined by EU Regulation 2021/821.

3. Category 3 Cryptographic Means (Annex 2)

Category 3 cryptographic means, outlined in Annex 2 of the Decree, apply to consumer-facing products that are less complex but still critical for security. These are often products marketed to the general public and must meet specific criteria:

Unmodifiable by End-Users: Cryptographic products under Category 3 must not be easily altered by end-users. This ensures the integrity of the product’s security features.
Limited Supplier Involvement: These products should be user-friendly, not requiring extensive assistance from the supplier for installation or continued use.

An example of a Category 3 product might be a mobile application that offers end-to-end encryption, ensuring ease of use for consumers while adhering to strict cryptographic security protocols.

Regulatory Framework and Implications

Decree No. 2007-663, alongside EU Regulation 2021/821, sets the groundwork for regulating cryptographic means in France and the broader European Union. Businesses must comply with these regulations, ensuring they declare or obtain the proper ANSSI cryptography authorization for all cryptographic operations. Compliance with these legal frameworks is non-negotiable, as they help prevent the misuse of cryptographic products for malicious purposes, such as espionage or terrorism.

Displaying ANSSI Cryptography Authorization: Transparency and Trust

Publicly showcasing your ANSSI cryptography authorization not only demonstrates regulatory compliance but also strengthens your business’s credibility. In fact, there are no legal restrictions preventing companies from making their authorization certificates visible. By displaying this certification, you reinforce transparency and trustworthiness, especially when dealing with clients or partners who prioritize data security and regulatory adherence.

Moreover, doing so can provide a competitive edge. Customers and stakeholders are reassured by visible compliance with both French and European standards, including Decree No. 2007-663 and EU Regulation 2021/821. Displaying this certificate prominently, whether on your website or in official communications, signals your business’s proactive stance on cybersecurity.

Final Steps to Ensure Compliance

Now that you understand the steps involved in ANSSI cryptography authorization, you are better equipped to meet the regulatory requirements for importing and exporting cryptographic means. By diligently completing the necessary forms, submitting the required documentation, and adhering to the outlined deadlines, you can streamline your operations and avoid potential delays or penalties. Moreover, by staying up-to-date with both French and European regulations, such as Decree No. 2007-663 and EU Regulation 2021/821, your business will maintain full compliance.

For any additional guidance, don’t hesitate to reach out to the ANSSI team or explore their resources further on their official website. By taking these proactive steps, you can ensure that your cryptographic operations remain fully compliant and seamlessly integrated into global standards.

Understanding the Impact and Evolution of Side-Channel Attacks in Modern Cybersecurity

Side-channel attacks, also known as side-channel exploitation, involve intercepting electromagnetic emissions from HDMI cables to capture and reconstruct the data displayed on a screen. These attacks, which were previously limited to analog signals like VGA, have now become possible on digital signals thanks to advances in artificial intelligence.

A group of researchers from the University of the Republic in Montevideo, Uruguay, recently demonstrated that even digital signals, once considered more secure, can be intercepted and analyzed to reconstruct what is displayed on the screen. Their research, published under the title “Deep-TEMPEST: Using Deep Learning to Eavesdrop on HDMI from its Unintended Electromagnetic Emanations”, is available on the arXiv preprint server (ar5iv).

Complementing this, Freemindtronic, a company specializing in cybersecurity, has also published articles on side-channel attacks. Their work highlights different forms of these attacks, such as acoustic or thermal emissions, and proposes advanced strategies for protection. You can explore their research and recommendations for a broader understanding of the threats associated with side-channel attacks by following this link: Freemindtronic – Side-Channel Attacks.

Freemindtronic Solutions for Combating Side-Channel Attacks via HDMI

Freemindtronic’s PassCypher and DataShielder product lines incorporate advanced hardware security technologies, such as NFC HSM (Hardware Security Module) or HSM PGP containers, to provide enhanced protection against side-channel attacks.

How Do These Products Protect Against HDMI Attacks?

PassCypher NFC HSM and PassCypher HSM PGP: These devices are designed to secure sensitive data exchanges using advanced cryptographic algorithms considered post-quantum, and secure key management methods through segmentation. Thanks to their hybrid HSM architecture, these devices ensure that cryptographic keys always remain in a secure environment, protected from both external and internal attacks, including those attempting to capture electromagnetic signals via HDMI. Even if an attacker managed to intercept signals, they would be unusable without direct access to the cryptographic keys, which remain encrypted even during use. Furthermore, credentials and passwords are decrypted only ephemerally in volatile memory, just long enough for auto-login and decryption.
DataShielder NFC HSM: This product goes even further by combining hardware encryption with NFC (Near Field Communication) technology. DataShielder NFC HSM is specifically designed to secure communications between phones and computers or exclusively on phones, ensuring that encryption keys are encrypted from the moment of creation and decrypted only in a secure environment. The messages remain encrypted throughout. This means that even if data were intercepted via a side-channel attack, it would remain indecipherable without the decryption keys stored within the HSM. Additionally, the NFC technology limits the communication range, reducing the risk of remote interception, as even the information transmitted via the NFC channel is encrypted with other segmented keys.

Why Are These Products Effective Against HDMI Attacks?

Segmented Cryptographic Key Protection: The hybrid HSMs integrated into these products ensure that cryptographic keys never leave the secure environment of the module. Even if an attacker were to capture HDMI signals, without access to the keys, the data would remain protected.
Encryption from NFC HSM or HSM PGP: Hybrid encryption, using keys stored in a secure enclave, is far more secure than software-only encryption because it is less likely to be bypassed by side-channel attacks. The PassCypher and DataShielder solutions use advanced AES-256 CBC PGP encryption, making it much harder for attackers to succeed.
Electromagnetic Isolation: These devices are designed to minimize electromagnetic emissions as much as possible and only on demand in milliseconds, making side-channel attacks extremely difficult to implement. Moreover, the data exchanged is encrypted within the NFC signal, significantly reducing the “attack surface” for electromagnetic signals. This prevents attackers from capturing exploitable signals.
Limitation of Communications: With NFC technology, communications are intentionally limited to short distances, greatly complicating attempts to intercept data remotely.

In summary

Freemindtronic’s PassCypher NFC HSM, PassCypher HSM PGP, and DataShielder NFC HSM products offer robust protection against side-channel attacks via HDMI. By integrating hardware security modules, advanced encryption algorithms, and limiting communications to very short distances, these devices ensure high-level security, essential for sensitive environments where data must be protected against all forms of attacks, including those using side-channel techniques.

ITAR’s Scope and Impact on Dual-Use Encryption

What is ITAR and How Does It Apply to Dual-Use Encryption?

ITAR plays a critical role in regulating dual-use encryption technologies. It controls the export of items listed on the United States Munitions List (USML), which includes certain encryption systems. These regulations apply when encryption technologies can be used for both military and civilian purposes. Therefore, companies dealing in dual-use encryption must adhere to ITAR’s stringent guidelines.

Understanding ITAR’s Dual-Use Encryption Requirements

ITAR dual-use encryption regulations demand that companies ensure their technologies do not fall into unauthorized hands. This applies to cryptographic systems with both commercial and military applications. Compliance requires a thorough understanding of ITAR’s legal framework, including the Directorate of Defense Trade Controls (DDTC). Companies must navigate these regulations carefully to avoid significant legal and financial repercussions.

ITAR’s Impact on Dual-Use Authentication Technologies

In addition to encryption, ITAR also governs certain dual-use authentication technologies. These include systems crucial for military-grade security. Companies must determine whether their authentication technologies are subject to ITAR and, if so, ensure full compliance. For a deeper understanding, refer to the Comprehensive Guide to Implementing DDTC’s ITAR Compliance Program.

Compliance with ITAR: Key Considerations for Dual-Use Encryption

ITAR Licensing Requirements for Dual-Use Encryption Technologies

Obtaining the necessary export licenses is critical for companies dealing with dual-use encryption under ITAR. The licensing process requires a detailed review of the technology to classify it under the USML. Companies must secure the correct licenses before exporting encryption products. Non-compliance with ITAR’s licensing requirements can result in severe penalties, including fines and imprisonment.

Risks of Non-Compliance with ITAR Dual-Use Encryption

Non-compliance with ITAR’s dual-use encryption regulations poses significant risks. These include hefty fines, loss of export privileges, and potential criminal charges against company executives. Moreover, non-compliance can damage a company’s reputation, particularly when seeking future contracts with government entities. Therefore, it is essential to implement robust compliance programs and regularly review them to mitigate these risks.

Enhancing Focus on Global Operations in ITAR Dual-Use Encryption Compliance

ITAR Compliance Challenges in Global Operations

ITAR dual-use encryption regulations extend beyond U.S. borders, affecting global operations. Companies with international subsidiaries or partners must navigate ITAR’s extraterritorial reach. This makes compliance challenging, especially in regions with different regulatory frameworks. For instance, a company operating in both the U.S. and Europe must align its operations with both ITAR and EU regulations.

Signal’s Position on End-to-End Messaging Encryption Regulation

Signal, a secure messaging app known for its commitment to privacy, has taken a strong stance against the proposed regulation. Meredith Whittaker, president of Signal, has described the European legislative proposal as “surveillance wine in security bottles.” In the face of this legislative proposal, Signal has even threatened to cease its activities in Europe. Despite this, Whittaker affirmed that the company would stay in Europe to support the right to privacy of European citizens.

WhatsApp’s Concerns on End-to-End Messaging Encryption Regulation

WhatsApp, another major player in the messaging app field, has also expressed concerns about the proposed regulation. Helen Charles, a public affairs representative for WhatsApp, expressed “concerns regarding the implementation” of such a solution at a seminar. She stated, “We believe that any request to analyze content in an encrypted messaging service could harm fundamental rights.” Charles advocates for the use of other techniques, such as user reporting and monitoring internet traffic, to detect suspicious behavior.

Twitter’s Consideration of End-to-End Messaging Encryption

In 2022, Elon Musk discussed the possibility of integrating end-to-end encryption into Twitter’s messaging. He stated, “I should not be able to access anyone’s private messages, even if someone put a gun to my head” and “Twitter’s private messages should be end-to-end encrypted like Signal, so that no one can spy on or hack your messages.”

Mailfence’s Emphasis on End-to-End Encryption

Mailfence, a secure email service, has declared that end-to-end encryption plays a crucial role in setting up secure messaging. They believe it’s extremely important to protect online privacy.

Meta’s Deployment of End-to-End Encryption

Meta (formerly Facebook) recently deployed end-to-end encryption by default for Messenger conversations. This means that only the sender and recipient can access the content of the messages, with Meta being unable to view them.

Other Messaging Apps’ Views on End-to-End Encryption

Other messaging apps have also expressed their views on end-to-end encryption:

Europol’s View

The heads of European police, including Europol, have expressed their need for legal access to private messages. They have emphasized that tech companies should be able to analyze these messages to protect users. Europol’s director, Catherine De Bolle, even stated, “Our homes are becoming more dangerous than our streets as crime spreads online. To ensure the safety of our society and our citizens, we need this digital environment to be secure. Tech companies have a social responsibility to develop a safer environment where law enforcement and justice can do their job. If the police lose the ability to collect evidence, our society will not be able to prevent people from becoming victims of criminal acts”.

Slack’s View

Slack, a business communication platform, has emphasized the importance of end-to-end encryption in preserving the confidentiality of communications and ensuring business security.

Google’s View

Google Messages uses end-to-end encryption to prevent unauthorized interception of messages. Encryption ensures that only legitimate recipients can access the exchanged messages, preventing malicious third parties from intercepting or reading conversations.

Encryption, especially end-to-end, is becoming an essential tool for securing the confidentiality of all users’ communications, including those of children. Any restrictions or infringements on end-to-end encryption can potentially be exploited by malicious third parties. No provision of this regulation should be construed as prohibiting, weakening, or compromising end-to-end encryption. Information society service providers should not face any barriers in offering their services using the highest encryption standards, as this encryption is crucial for trust and security in digital services.

The regulation permits service providers to select the technologies they employ to comply with detection orders. It should not be interpreted as either encouraging or discouraging the use of a specific technology, as long as the technologies and accompanying measures adhere to the requirements of this regulation. This includes the use of end-to-end encryption technology, a vital tool for ensuring the security and confidentiality of users’ communications, including those of children.

When implementing the detection order, providers should employ all available safeguards to ensure that the technologies they use cannot be exploited by them, their employees, or third parties for purposes other than compliance with this regulation. This helps to avoid compromising the security and confidentiality of users’ communications while ensuring the effective detection of child sexual abuse material and balancing all fundamental rights involved. In this context, providers should establish effective internal procedures and safeguards to prevent general surveillance. Detection orders should not apply to end-to-end encryption.

Advantages and Disadvantages of End-to-End Messaging Encryption

TETRA Security Vulnerabilities: How to Protect Critical Infrastructures from Cyberattacks

TETRA (Terrestrial Trunked Radio) is a radio technology that is used worldwide for critical communications and data, especially in the sectors of security, energy, transport and defense. But this technology, which has been kept secret for more than 25 years, hides serious security vulnerabilities, including a backdoor that could allow devastating cyberattacks.

What is TETRA?

TETRA is a European radio standard that was developed in the 1990s to meet the needs of professional mobile services, such as police, firefighters, emergency services, military, prison staff, etc. TETRA allows to transmit data and voice encrypted on frequencies ranging from 380 to 470 MHz, with a range of several kilometers.

TETRA is used by more than 2000 networks in more than 150 countries, according to the TETRA and Critical Communications Association (TCCA), which brings together the manufacturers, operators and users of this technology. Among the main manufacturers of TETRA radios, we find Motorola Solutions, Hytera, Airbus, Sepura and Rohill.

TETRA offers several advantages over other radio technologies, such as:

better sound quality
greater transmission capacity
greater security thanks to encryption
greater flexibility thanks to the possibility of creating communication groups
greater interoperability thanks to the compatibility of equipment

What are the vulnerabilities of TETRA?

Despite its strengths, TETRA also has weaknesses, which have been revealed by a group of Dutch researchers from Radboud University Nijmegen. These researchers conducted a thorough analysis of the TETRA standard and its encryption algorithms, which were until then kept secret by the manufacturers and authorities.

The researchers discovered two types of major vulnerabilities in TETRA:

A backdoor in the encryption algorithm TEA1, which is used in radios sold for sensitive equipment, such as pipelines, railways, power grid, public transport or freight trains. This backdoor allows an attacker to decrypt the communications and data transmitted by these radios, and possibly to modify or block them. The backdoor exists since the creation of the algorithm TEA1, in 1998, and cannot be corrected by a simple software update. The researchers managed to extract the secret key of the backdoor by analyzing the binary code of the radios.
A weakness in the encryption algorithm TEA2, which is used in radios intended for professional mobile services, such as police, firefighters, emergency services, military or prison staff. This weakness allows an attacker to reduce the number of possible keys to test to decrypt the communications and data transmitted by these radios. The researchers estimated that it would take about 10 minutes to find the right key with a standard computer. This weakness was corrected by the manufacturers in 2016, but the radios that have not been updated remain vulnerable.

To find the backdoor in the TEA1 algorithm, the researchers used a technique called “differential analysis”, which consists of comparing the outputs of the algorithm for slightly different inputs. By observing the differences, they were able to identify a part of the code that was not normally used, but that was activated by a special condition. This condition was the presence of a secret key of 64 bits, which was hidden in the binary code of the radios. By analyzing the code, they were able to extract the secret key and test it on encrypted communications with the TEA1 algorithm. They were thus able to confirm that the secret key allowed to decrypt the communications without knowing the normal key of 80 bits. The researchers published their official report and the source code of the TETRA encryption algorithms on their website.

What are the risks for critical infrastructures?

The vulnerabilities identified in TETRA represent a danger for the critical infrastructures that use this technology, because they could be exploited by cybercriminals, terrorists or spies to disrupt or damage these infrastructures.

For example, an attacker could:

listen to the communications and confidential data of the security or defense services
impersonate an operator or a manager to give false instructions or orders
modify or erase data or commands that control vital equipment, such as valves, switches, signals or brakes
cause failures, accidents, fires or explosions

These scenarios could have dramatic consequences on the security, health, economy or environment of the countries concerned.

How to protect yourself from cyberattacks on TETRA?

The users of TETRA must be aware of the vulnerabilities of this technology and take measures to protect themselves from potential cyberattacks. Among the recommendations of the researchers, we can mention:

check if the radios used are affected by the vulnerabilities and ask the manufacturers for correction solutions
avoid using the algorithm TEA1, which contains the backdoor, and prefer safer algorithms, such as TEA3 or TEA4
use encryption keys that are long and complex enough, and change them regularly
set up verification and authentication procedures for communications and data
monitor the radio traffic and detect anomalies or intrusion attempts
raise awareness and train staff on cybersecurity and good practices

TETRA digital mode: how to transfer data via TETRA

TETRA (Terrestrial Trunked Radio) is a digital and secure radio communication standard used by emergency services, law enforcement, public transport and industries. TETRA uses a π/4-DQPSK phase modulation and a TDMA time division multiplexing to transmit voice and data on a bandwidth of 25 KHz per transmission channel. Each channel is divided into four timeslots, one of which is reserved for signaling in trunked mode (TMO).

TETRA allows file transfer via radio in two ways: by the packet data service (PDS) or by the circuit data service (CDS).

The PDS uses the IP protocol to transmit data packets on one or more timeslots. It offers a maximum throughput of 28.8 kbit/s per timeslot, or 86.4 kbit/s for three timeslots. The PDS can be used to send small files, such as images, text messages or forms.

The CDS uses the LAPD protocol to transmit data by circuit on a dedicated timeslot. It offers a constant throughput of 4.8 kbit/s per timeslot, or 19.2 kbit/s for four timeslots. The CDS can be used to send large files, such as documents, videos or maps.

The choice of the data service depends on the type of file, the size of the file, the quality of the radio link, the cost and the availability of radio resources. The PDS offers more flexibility and performance, but it requires a good signal quality and it can be more expensive in terms of battery consumption and spectrum occupation. The CDS offers more reliability and simplicity, but it requires a prior allocation of a timeslot and it can be slower and less efficient.

Securing TETRA file transfers with Freemindtronic’s EviCypher technology

However, both data services are subject to the TETRA security vulnerabilities that we have discussed in the previous sections. These vulnerabilities could allow an attacker to intercept, modify or corrupt the files transferred via TETRA, or to prevent their transmission altogether. Therefore, the users of TETRA must ensure the integrity and the confidentiality of the files they send or receive, by using encryption, verification and authentication methods. Freemindtronic’s EviCypher technology can be a valuable solution for encrypting data with post-quantum AES-256 from an NFC HSM with your own randomly generated keys before transferring them via TETRA. This way, even if an attacker corrupts the data transmitted by TETRA, they will not be able to decrypt the data encrypted by a product embedding

How to secure file transfers via TETRA with Freemindtronic’s EviCypher technology

La technologie EviCypher de Freemindtronic peut être une solution précieuse pour chiffrer les données avec AES-256 post-quantique à partir d’un HSM NFC avec vos propres clés générées aléatoirement avant de les transférer via TETRA. Ainsi, même si un attaquant corrompt les données transmises par TETRA, il ne pourra pas décrypter les données cryptées par un produit embarquant la technologie EviCypher NFC HSM technology, such as DataShielder NFC HSM or DataSielder Defense NFC HSM. These products are portable and autonomous devices that allow you to secure the access to computer systems, applications or online services, using the NFC as a means of authentication and encryption.

The management of encryption keys for TETRA

To use encryption on the TETRA network, you need an encryption key, which is a secret code of 80 bits, or 10 bytes. This key must be shared between the radios that want to communicate securely, and must be protected against theft, loss or compromise.

There are several methods to save and enter encryption keys for TETRA, depending on the type of radio and the level of security required. Here are some examples:

The manual method: it consists of entering the encryption key using the keyboard of the radio, by typing the 10 bytes in hexadecimal form. This method is simple, but impractical and unsafe, because it requires to know the key by heart or to write it down on a support, which increases the risk of disclosure or error. For example, a 80-bit key could be 3A4F9C7B12E8D6F0.
The automatic method: it consists of using an external device, such as a computer or a smart card, which generates and transfers the encryption key to the radio by a cable or a wireless link. This method is faster and more reliable, but it requires to have a compatible and secure device, and to connect it to the radio at each key change.
The EviPass method: it consists of using the EviPass NFC HSM technology which allows to generate, store and manage keys and secrets in a secure and independent NFC HSM device. This method is the most innovative and secure, because it allows to create keys higher than 80 bits randomly in hexadecimal base 16, 58, 64 or 85, to store them in a physical device protected by an access code and a robust AES-256 post-quantum encryption algorithm, and to transfer them by various contactless means, via a computer. This method does not require to know or write down the key, which reduces the risk of disclosure or error. For example, a 10-byte key of 80 bits could be 3F 8A 6B 4C 9D 1E 7F 2A 5B 0C.

The EviPass NFC HSM technology of Freemindtronic allows to create secure gateways between the NFC devices and the computer systems, using advanced encryption protocols, such as AES, RSA or ECC. The EviPass NFC HSM technology is embedded in the PassCyber NFC HSM product, which is a portable and autonomous device that allows to secure the access to computer systems, applications or online or offligne services, using the NFC as a means of authentication.

Conclusion

TETRA is a radio technology that was designed to offer secure and reliable communication to professional mobile services and critical infrastructures. But this technology, which has been kept secret for decades, presents vulnerabilities that could be exploited by cyberattackers to compromise these communications and infrastructures. The users of TETRA must be vigilant and take measures to protect themselves from these threats, by updating their equipment, choosing robust encryption algorithms, using strong keys, verifying and authenticating data and monitoring radio traffic. The EviPass NFC HSM technology of Freemindtronic can be an effective solution to strengthen the security of keys and secrets used for verification and authentication, by storing them in a secure and independent NFC device. The researchers who revealed the vulnerabilities of TETRA hope that their work will contribute to improve the security of communications in critical domains.

The international regulations on dual-use encryption products

The main international regulations that apply to dual-use encryption products are the Wassenaar Arrangement and the EU regime for the control of exports of dual-use goods.

The Wassenaar Arrangement

The Wassenaar Arrangement is a multilateral export control regime that aims to contribute to regional and international security and stability. It promotes transparency and responsibility in the transfers of conventional arms and dual-use goods and technologies. It was established in 1996 and currently has 42 participating states, including the United States, Canada, Japan, Australia, Russia, China and most of the EU member states.

The Wassenaar Arrangement maintains a list of dual-use goods and technologies that are subject to export control by the participating states. The list is divided into 10 categories, with subcategories and items. Category 5, part 2, covers information security, including encryption products. The list of encryption products includes, among others, the following items:

Cryptographic systems, equipment, components and software, using symmetric or asymmetric algorithms, with a key length exceeding 56 bits for symmetric algorithms or 512 bits for asymmetric algorithms, or specially designed for military or intelligence use.
Cryptanalytic systems, equipment, components and software, capable of recovering the plain text from the encrypted text, or of finding cryptographic keys or algorithms.
Cryptographic development systems, equipment, components and software, capable of generating, testing, modifying or evaluating cryptographic algorithms, keys or systems.
Non-cryptographic information security systems, equipment, components and software, using techniques such as steganography, watermarking, tamper resistance or authentication.
Technology for the development, production or use of the above items.

The participating states of the Wassenaar Arrangement are required to implement national export controls on the items listed in the arrangement, and to report annually their exports and denials of such items. However, the arrangement does not impose binding obligations on the participating states, and each state is free to decide whether to grant or refuse an export license, based on its own policies and national interests.

The EU regime for the control of exports of dual-use goods

The common legal framework of the EU for dual-use goods

The EU regime for the control of exports of dual-use goods is a common legal framework. It applies to all EU member states, and it has two main goals. First, it aims to ensure a consistent and effective implementation of the international obligations of export control. Second, it aims to protect the security and human rights of the EU and its partners. The regime is based on the Regulation (EU) 2021/821, which was adopted in May 2021 and entered into force in September 2021. This regulation replaces the previous Regulation (EC) No 428/2009.

The Regulation (EU) 2021/821: the principles and criteria of export control

The Regulation (EU) 2021/821 establishes a Union list of dual-use goods. These are goods that can have both civilian and military uses, such as software, equipment and technology. These goods are subject to an export authorization, which means that exporters need to obtain a permission from the competent authorities before exporting them. The Regulation also sets out a set of general principles and criteria for granting or refusing such authorization. The Union list of dual-use goods is based on the international export control regimes, including the Wassenaar Arrangement. It covers the same categories and items as the latter. However, the EU list also includes some additional items that are not covered by the international regimes. These are cyber-surveillance items that can be used for internal repression or human rights violations.

The Union list of dual-use goods: the categories and items subject to an export authorization

The Union list of dual-use goods consists of ten categories, which are:

Category 0: Nuclear materials, facilities and equipment
Category 1: Materials, chemicals, micro-organisms and toxins
Category 2: Materials processing
Category 3: Electronics
Category 4: Computers
Category 5: Telecommunications and information security
Category 6: Sensors and lasers
Category 7: Navigation and avionics
Category 8: Marine
Category 9: Aerospace and propulsion

Each category contains a number of items, which are identified by a code and a description. For example, the item 5A002 is “Information security systems, equipment and components”. The items are further divided into sub-items, which are identified by a letter and a number. For example, the sub-item 5A002.a.1 is “Cryptographic activation equipment or software designed or modified to activate cryptographic capability”.

The novelties of the Regulation (EU) 2021/821: the due diligence obligation, the catch-all clause, the human security approach and the transparency and information exchange mechanism

The Regulation (EU) 2021/821 also provides for different types of export authorizations. These are individual, global, general or ad hoc authorizations, depending on the nature, destination and end-use of the items. Moreover, the Regulation introduces some novelties, such as:

A due diligence obligation for exporters. This means that exporters have to verify the end-use and the end-user of the items, and to report any suspicious or irregular transaction.
A catch-all clause. This allows the competent authorities to impose an export authorization on items that are not listed, but that can be used for weapons of mass destruction, a military end-use, human rights violations or terrorism.
A human security approach. This requires the competent authorities to take into account the potential impact of the items on human rights, international humanitarian law, regional stability and sustainable development, especially for cyber-surveillance items.
A transparency and information exchange mechanism. This requires the competent authorities to share information on the authorizations, denials and consultations of export, and to publish annual reports on their export control activities.

The dual-use encryption products: sensitive goods for security and human rights

The dual-use encryption products are a specific type of dual-use goods that fall under the category 5 of the Union list. These are products that use cryptographic techniques to protect the confidentiality, integrity and authenticity of data and communications. These products can have both civilian and military uses, and they raise important issues for security and human rights.

The dual-use encryption products: a definition and examples

The dual-use encryption products are defined by the Regulation (EU) 2021/821 as “information security systems, equipment and components, and ‘software’ and ‘technology’ therefor, which use ‘cryptography’ or cryptanalytic functions”. The Regulation also provides a list of examples of such products, such as:

Cryptographic activation equipment or software
Cryptographic equipment for mobile cellular systems
Cryptographic equipment for radio communication systems
Cryptographic equipment for computer and network security
Cryptanalytic equipment and software
Quantum cryptography equipment and software

The dual-use encryption products: security issues

The dual-use encryption products can have a significant impact on the security of the EU and its partners. On the one hand, these products can enhance the security of the EU and its allies, by protecting their sensitive data and communications from unauthorized access, interception or manipulation. On the other hand, these products can also pose a threat to the security of the EU and its adversaries, by enabling the encryption of malicious or illegal activities, such as terrorism, espionage or cyberattacks. Therefore, the export of these products needs to be carefully controlled, to prevent their misuse or diversion to undesirable end-users or end-uses.

The dual-use encryption products: human rights issues

The dual-use encryption products can also have a significant impact on the human rights of the EU and its partners. On the one hand, these products can protect the human rights of the EU and its citizens, by safeguarding their privacy and freedom of expression on the internet. On the other hand, these products can also violate the human rights of the EU and its partners, by enabling the repression or surveillance of dissidents, activists or journalists by authoritarian regimes or non-state actors. Therefore, the export of these products needs to take into account the potential consequences of the items on human rights, international humanitarian law, regional stability and sustainable development, especially for cyber-surveillance items.

The modification of the Union list of dual-use goods by the Delegated Regulation (EU) 2022/1

The Union list of dual-use goods is not static, but dynamic. It is regularly updated to reflect the changes in the technological development and the international security environment. The latest update of the list was made by the Delegated Regulation (EU) 2022/1 of the Commission of 20 October 2021, which modifies the Regulation (EU) 2021/821.

The changes made by the international export control regimes in 2020 and 2021

The Delegated Regulation (EU) 2022/1 reflects the changes made by the international export control regimes in 2020 and 2021. These are the Wassenaar Arrangement, the Nuclear Suppliers Group, the Australia Group and the Missile Technology Control Regime. These regimes are voluntary and informal arrangements of states that coordinate their national export control policies on dual-use goods. The EU is a member of these regimes, and it aligns its Union list of dual-use goods with their lists of controlled items. The changes made by these regimes include the addition, deletion or modification of some items, as well as the clarification or simplification of some definitions or technical parameters.

The new items added to the Union list of dual-use goods: the quantum technologies, the drones and the facial recognition systems or biometric identification systems

The Delegated Regulation (EU) 2022/1 also adds some new items to the Union list of dual-use goods. These are items that are not covered by the international export control regimes, but that are considered to be sensitive for the security and human rights of the EU and its partners. These items include:

Certain types of software and technology for the development, production or use of quantum computers or quantum cryptography. These are devices or techniques that use the principles of quantum physics to perform computations or communications that are faster or more secure than conventional methods.
Certain types of equipment, software and technology for the development, production or use of unmanned aerial vehicles (UAVs) or drones. These are aircraft or systems that can fly without a human pilot on board, and that can be used for various purposes, such as surveillance, reconnaissance, delivery or attack.
Certain types of equipment, software and technology for the development, production or use of facial recognition systems or biometric identification systems. These are systems or techniques that can identify or verify the identity of a person based on their facial features or other biological characteristics, such as fingerprints, iris or voice.

The entry into force and application of the Delegated Regulation (EU) 2022/1

The Delegated Regulation (EU) 2022/1 entered into force on 7 January 2022. It applies to all exports of dual-use goods from the EU from that date. The exporters of dual-use goods need to be aware of the changes and updates to the Union list of dual-use goods, and to comply with the export control rules and procedures established by the Regulation (EU) 2021/821. The competent authorities of the member states need to implement and enforce the new Union list of dual-use goods, and to cooperate and coordinate with each other and with the Commission. The Commission needs to monitor and evaluate the impact and effectiveness of the new Union list of dual-use goods, and to report to the European Parliament and the Council.

The national regulations on dual-use encryption products

How some countries have their own rules on dual-use encryption products

The case of the United States

Some countries have their own national regulations on dual-use encryption products, which may differ or complement the existing regimes. For example, the United States has a complex and strict export control system, based on the Export Administration Regulations (EAR). The EAR classify encryption products under category 5, part 2, of the Commerce Control List (CCL). The EAR require an export license for most encryption products, except for some exceptions, such as mass market products, publicly available products, or products intended for certain countries or end-users. The EAR also require that exporters submit annual self-classification reports, semi-annual sales reports, and encryption review requests for certain products.

The case of Andorra

Andorra is a small country between France and Spain. It is not an EU member, but it has a customs union with it. However, this customs union does not cover all products. It only covers those belonging to chapters 25 to 97 of the Harmonized System (HS), which are mainly industrial products. Agricultural products and products belonging to chapters 1 to 24 of the HS are free of import duties in the EU. But they are subject to the most-favored-nation (MFN) treatment in Andorra.

Andorra has adopted the EU list of dual-use goods. It requires an export or transfer authorization for these goods, according to the Regulation (EU) 2021/821. This regulation came into force on 9 September 2021 and replaced the previous Regulation (EC) No 428/2009. Andorra has also adopted the necessary customs provisions for the proper functioning of the customs union with the EU. These provisions are based on the Community Customs Code and its implementing provisions, by the Decision No 1/2003 of the Customs Cooperation Committee.

Andorra applies the EU regulation, as it is part of the internal market. Moreover, Andorra has adopted the Delegated Regulation (EU) 2022/1 of the Commission of 20 October 2021, which modifies the EU list of dual-use goods. This modification reflects the changes made by the international export control regimes in 2020 and 2021. It also adds some new items, such as software and technologies for quantum computing, drones or facial recognition. The Delegated Regulation (EU) 2022/1 came into force on 7 January 2022, and applies to all exports of dual-use goods from the EU from that date.

Andorra entered the security and defense sector for the first time by participating in Eurosatory 2022. This is the international reference exhibition for land and airland defense and security. Andorra became the 96th country with a security and defense industry on its territory. Among the exhibitors, an Andorran company, Freemindtronic, specialized in counter-espionage solutions, presented innovative products. For example, DataShielder Defense NFC HSM, a device to protect sensitive data against physical and logical attacks. It uses technologies such as EviCypher NFC HSM and EviCore NFC HSM, contactless hardware security modules (NFC HSM). The president of Coges events, a subsidiary of GICAT, identified these products as dual-use and military products. They need an export or transfer authorization, according to the Regulation (EU) 2021/821. Freemindtronic also showed its other security solutions, such as EviKey NFC HSM, a secure USB key, a security token. These products were displayed in the Discover Village, a space for start-ups and SMEs innovations.

Switzerland

Switzerland is not an EU member, but it has a free trade agreement with it. Switzerland has adopted the Regulation (EU) 2021/821 by the Ordinance of 5 May 2021 on the control of dual-use goods. Switzerland applies the EU list of dual-use goods and requires an export or transfer authorization for these goods, according to the Regulation (EU) 2021/821. Switzerland has also adopted the Delegated Regulation (EU) 2022/1 of the Commission of 20 October 2021, which modifies the EU list of dual-use goods.

Turkey

Turkey is not an EU member, but it has a customs union with it. Turkey has adopted the Regulation (EU) 2021/821 by the Presidential Decree No 3990 of 9 September 2021 on the control of exports of dual-use goods. Turkey applies the EU list of dual-use goods and requires an export or transfer authorization for these goods, according to the Regulation (EU) 2021/821. Turkey has also adopted the Delegated Regulation (EU) 2022/1 of the Commission of 20 October 2021, which modifies the EU list of dual-use goods.

United Kingdom

The United Kingdom left the EU on 31 January 2020. It has adopted the Regulation (EU) 2021/821 by the Dual-Use Items (Export Control) Regulations 2021, which came into force on 9 September 2021. The United Kingdom applies the EU list of dual-use goods and requires an export or transfer authorization for these goods, according to the Regulation (EU) 2021/821. The United Kingdom has also adopted the Delegated Regulation (EU) 2022/1 of the Commission of 20 October 2021, which modifies the EU list of dual-use goods.

The challenges and opportunities for the exporters of dual-use encryption products

The exporters of dual-use encryption products face several challenges and opportunities in the current context of export control regulations. Among the challenges, we can mention:

The complexity and diversity of the regulations, which may vary depending on the countries, the products, the destinations and the end-uses, and which require a deep knowledge and a constant monitoring from the exporters.
The costs and delays related to the administrative procedures, which can be high and unpredictable, and which can affect the competitiveness and profitability of the exporters, especially for small and medium enterprises (SMEs).
The legal and reputational risks, which can result from an involuntary or intentional violation of the regulations, or from a misuse or diversion of the products by the end-users, and which can lead to sanctions, prosecutions or damages to the image of the exporters.

Among the opportunities, we can mention:

The growing demand and innovation for encryption products, which are increasingly used in many sectors and domains, such as finance, health, education, defense, security, human rights, etc.
The contribution to the security and human rights of the exporters, their customers and the general public, by enabling the protection of data, privacy, freedom of expression, access to information and democratic participation, thanks to encryption products.
The cooperation with the competent authorities, the civil society and the international community, to ensure the compliance and accountability of the exporters, and to support the development and implementation of effective and balanced encryption policies and regulations, that respect the security and human rights of all stakeholders.

Conclusion

Dual-use encryption products can have both civil and military uses. They are subject to export control regulations at different levels: international, regional and national. These regulations aim to prevent the risks that these products can pose for security and human rights. At the same time, they allow the development and trade of these products. Therefore, the exporters of dual-use encryption products must comply with the regulations that apply to their products. They must also assess the impact of their products on security and human rights. The exporters of dual-use encryption products can benefit from the demand and innovation for these products.

How the RSA Encryption – Marvin Attack Reveals a 25-Year-Old Flaw and How to Protect Your Secrets with the NFC HSM Devices

RSA encryptionRSA encryption is one of the most widely used encryption algorithms in the world, but it is not flawless. In fact, a vulnerability of RSA encryption, known as the Marvin attack, has existed for over 25 years and could allow an attacker to recover the private key of a user from their public key. This flaw, which exploits a mathematical property of RSA encryption, was discovered in 1998 by the cryptographer Daniel Bleichenbacher, but it was never fixed or disclosed to the public. In the first part of this article, we will explain in detail how the Marvin attack works and what it means for the security of RSA encryption.

Moreover, NFC HSM and RSA 4096 represent a new dimension in cryptographic security. These technologies allow you to protect and use your cryptographic keys and secrets within a contactless device that communicates with your smartphone through NFC (Near Field Communication). The main advantage they offer is the formidable defense against cyberattacks, achieved by implementing state-of-the-art encryption algorithms and strong security protocols. You can discover more about the very simple functioning of NFC HSM devices for RSA 4096 encryption, as well as their multiple benefits, by reading until the end of this article. Moreover, we will highlight how Freemindtronic used the extreme level of safety of an NFC HSM device to establish, without contact and only on demand, a virtual communication tunnel encrypted in RSA-4096 without a server, without a database, from an NFC HSM device.

The Marvin Attack: Unveiling a 25-Year-Old RSA Flaw

Understanding the Marvin Attack

The Marvin attack targets the RSA algorithm, a foundational asymmetric encryption technique characterized by the use of two distinct keys: a public key and a private key. The public key serves to encrypt data, while the private key is responsible for decryption. These keys mathematically intertwine, yet revealing one from the other presents an exceedingly challenging task.

Named after Marvin the Paranoid Android from “The Hitchhiker’s Guide to the Galaxy,” this attack exploits a vulnerability in the RSA algorithm discovered by Swiss cryptographer Daniel Bleichenbacher in 1998. The vulnerability relates to the padding scheme that the RSA algorithm uses to introduce random bits into the data before encryption. The padding scheme has a design. It makes the encrypted data look random. It also thwarts attacks based on statistics. However, Bleichenbacher showed his ingenuity. He sent special messages to a server. The server used RSA encryption. By doing so, he could learn about the padding scheme. He could also recover the private key.

Implications of the Marvin Attack

The Marvin attack has profound implications for the security and confidentiality of your secrets. If an attacker successfully retrieves your private key, they gain unfettered access to decrypt all your encrypted data and compromise your confidential information. Furthermore, they can impersonate you by signing messages or executing transactions on your behalf.

The Marvin attack isn’t limited to a single domain; it can impact any system or application that uses RSA encryption with a vulnerable padding scheme. This encompasses web servers that employ HTTPS, email servers that use S/MIME, and blockchain platforms that rely on digital signatures.

Notably, NFC HSM devices that use RSA encryption for secret sharing are vulnerable to the Marvin attack. NFC HSM, short for Near Field Communication Hardware Security Module, is a technology facilitating the storage and utilization of cryptographic keys and secrets within contactless devices such as cards, stickers, or keychains. These devices communicate with smartphones via NFC, a wireless technology enabling short-range data exchange between compatible devices.

If an attacker intercepts communication between your NFC HSM device and smartphone, they may try a Marvin attack on your device, potentially recovering your private key. Subsequently, they could decrypt secrets stored within your device or gain access to your online accounts and services.

The Common Factor Attack in RSA Encryption

Understanding the Common Factor Attack

In the realm of RSA encryption, attackers actively exploit a vulnerability known as the Common Factor Attack. Here’s a concise breakdown:

1. Identifying Shared Factors

In RSA encryption, public keys (e, n) and private keys (d, n) play pivotal roles.
Attackers meticulously seek out common factors within two public keys, exemplified by (e1, n1) and (e2, n2).
Upon discovering a shared factor, their mission gains momentum.

2. Disclosing the Missing Factor

Once a common factor ‘p’ surfaces, uncovering its counterpart ‘q’ becomes relatively straightforward.
This is achieved through the simple act of dividing one key’s module by ‘p’.

3. Attaining Private Keys

How Does RSA 4096 Work?

RSA 4096 is built upon the foundation of asymmetric encryption, employing two distinct keys: a public key and a private key. The public key can be freely disseminated, while the private key must remain confidential. These keys share a mathematical relationship, but uncovering one from the other poses an exceptionally daunting challenge.

RSA 4096 hinges on the RSA algorithm, relying on the formidable complexity of factoring a large composite number into the product of two prime numbers. RSA 4096 employs prime numbers of 4096 bits in size, rendering factorization virtually impossible with current computational capabilities.

RSA 4096 facilitates four primary operations:

Encryption: Transforming plaintext messages into encrypted messages using the recipient’s public key. Only the recipient can decrypt the message using their private key.
Decryption: Retrieving plaintext messages from encrypted ones using the recipient’s private key. Only the recipient can perform this decryption.
Signature: Adding an authentication element to plaintext messages using the sender’s private key. The recipient can verify the signature using the sender’s public key.
Signature Verification: Validating the authenticity of plaintext messages and their sender using the sender’s public key.

In essence, RSA 4096 ensures confidentiality, integrity, and non-repudiation of exchanged messages.

But how can you choose and utilize secure RSA keys? Are there innovative solutions available to bolster the protection of cryptographic secrets?

Communication Vulnerabilities in 2023: Unveiling the Hidden Dangers and Strategies to Evade Cyber Threats

2023 Security Vulnerabilities in Means of Communication

Communication is essential for individuals and professionals, but it is also exposed to many cyber threats. In 2023, several security breaches affected emails and messages, compromising the security of data, services, and users. These breaches showed the vulnerability of communication systems, which are exposed to increasingly sophisticated and targeted attacks. To protect themselves, users need to encrypt their data and communications with their own keys that they created and stored offline. One of the solutions that can help them achieve this is EviCypher NFC HSM technology by Freemindtronic.

The Reality of Security Breaches in Communication Systems

However, we wanted to highlight a disconcerting reality: users often found themselves defenseless against the hidden dangers of communication vulnerabilities in 2023 that festered beneath the surface for long periods of time. Unaware of these current, imminent or future risks, they unwittingly provided gateways to espionage activities, whether motivated by legitimate or malicious intentions. These vulnerabilities enabled a relentless cycle of cyber victimization, perpetuating the very threats they aimed to mitigate.

For example, iCloud Email operated without end-to-end encryption from its launch in 2011 until December 2022 – a troubling reality that put users in a vulnerable position, their security at the mercy of external factors they could not control.

Another example, several reports by the Citizen Lab have revealed the existence and the use of Pegasus spyware developed by the Israeli company NSO Group, which sells its services to governments and private actors to spy on targets around the world. Moreover, several investigations by the consortium Forbidden Stories have revealed that more than 50,000 phone numbers have been selected as potential targets by NSO Group’s clients, including heads of state, journalists, human rights activists, etc.

Among the most recent examples of these vulnerabilities, we can mention the cyberattack against the US State Department, which was attributed to hackers linked to China.

Chinese hackers hacked 60,000 emails from the US State Department

In March 2023, Chinese hackers hacked 60,000 emails from the US State Department. Some of them were very sensitive to national security and foreign affairs. They used a Microsoft Exchange flaw named Log4Shell. This vulnerability allows hackers to remotely execute malicious code on servers that use this software. It affects millions of servers worldwide. Senator Mark Warner revealed the attack and criticized the lack of transparency and security of the State Department. He called for strengthening cooperation between government agencies and the private sector to cope with cyberthreats. This attack is part of a context of rising tensions between the US and China, who accuse each other of espionage and sabotage on cyberspace.

The other sensitive organs targeted by the attack

Besides the State Department emails, the attack also targeted other sensitive organs, such as:

The Bureau of the Coordinator for Cyber Issues, which is responsible for coordinating the State Department’s efforts to prevent and respond to cyberattacks.
The Bureau of Consular Affairs, which is in charge of issuing passports and visas, as well as protecting US citizens abroad.
The Bureau of Intelligence and Research, which provides analysis and assessments on foreign policy and national security issues.

These sensitive organs hold confidential or personal information that could be used by the Chinese hackers for espionage, blackmail or sabotage. For example, the hackers could access the biometric data of visa applicants, the reports of intelligence agents or the action plans in case of crisis.

The security flaw exploited by the Chinese hackers

The most serious thing is that some servers that were hacked by the Chinese had not been updated with the patch released by Microsoft on December 10, 2022. This shows that the updates are not automatic and that they have to be installed manually. This also shows the lack of responsiveness and vigilance of the IT security managers. They let the Chinese hackers exploit this flaw before it was fixed by Microsoft, who released security updates. Indeed, this cyberattack shows the vulnerability of communication systems and the need to protect them effectively.

A Case of Satellite Messaging Security Vulnerability

Satellite messaging is a means of communication that allows the transmission of electronic messages or calls via a network of artificial satellites. It is used by professionals and individuals in areas with no cellular coverage or those seeking discreet communication. However, satellite messaging is not immune to security vulnerabilities that can compromise data confidentiality and integrity.

In September 2023, a team of cybersecurity researchers uncovered a significant security vulnerability in the Bullitt satellite messaging service. This vulnerability allowed hackers to read and modify messages sent and received by users, as well as access their personal information, including GPS coordinates and phone numbers. Hackers could also impersonate users by sending messages on their behalf. The vulnerability was found in the PubNub-Kotlin API used by the Bullitt Messenger app to manage communication between devices and the service’s servers. Despite alerting Bullitt, the service provider, about this vulnerability, the researchers received no satisfactory response.

This security flaw poses a high risk to satellite messaging users, as their data can be exposed or manipulated by hackers.

Security Vulnerabilities in Communication Systems: A Closer Look

2023 Security Flaws in Communication Channels is a paramount concern for individuals and organizations across the globe. Hackers frequently exploit vulnerabilities within communication protocols and services to launch attacks that can compromise data confidentiality, integrity, and availability.

Among these email-targeted threats, ransomware attacks are the most prevalent, comprising 25% of reported security incidents. Additionally, it’s striking to note that 48% of malicious files attached to emails are Microsoft Office documents. These statistics underscore the critical importance of implementing robust security measures for emails to guard against evolving threats.

Furthermore, an analysis conducted by the Verizon Data Breach Investigations Report for 20232 highlights that emails remain the primary variety of malicious actions in data breaches, underscoring their continued relevance as a vector for cyberattacks.

However, it is essential to note that email-specific vulnerabilities can vary based on factors such as email protocol vulnerabilities, server configuration errors, human mistakes, among others.

Security Vulnerabilities in Encrypted Messaging Services

Encrypted messaging services like Signal, Telegram, or WhatsApp are not immune to security vulnerabilities, which can compromise message and file confidentiality, integrity, and availability. In March 2023, Cellebrite, an Israeli data extraction company, claimed to have successfully decrypted messages and files sent via Signal. In June 2023, Google disclosed a vulnerability in its RCS service that allowed hackers to send fraudulent messages to Android users, containing malicious links redirecting victims to compromised websites.

Security Vulnerabilities in Communication Protocols

Communication protocols such as SMTP, RCS, or SMS are also susceptible to security vulnerabilities that can enable hackers to intercept, modify, or spoof messages and calls. SS7 vulnerabilities involve attacks exploiting the vulnerabilities of the SS7 protocol, used to establish and terminate telephone calls on digital signaling networks. These attacks can allow hackers to intercept, modify, or spoof voice and SMS communications on a cellular network. In January 2023, a hacking group named Ransomware.vc launched a data extortion campaign targeting organizations using the Progress MOVEit file transfer tool. The hackers exploited an SS7 vulnerability to intercept verification codes sent via SMS to MOVEit users, gaining access to sensitive data. In February 2023, the Ukrainian power grid was hit by a new malware called Industroyer2, attributed to Russian hackers. The malware used an SS7 vulnerability to take control of network operator phone calls, disrupting electricity distribution in the country. In March 2023, Samsung suffered a data breach that exposed the personal and financial information of millions of customers. The breach was caused by an SS7 vulnerability that allowed hackers to access SMS messages containing online transaction confirmation codes.

An Overview of Security Vulnerabilities in Communication Systems

Communication systems exhibit various vulnerabilities, with each element susceptible to exploitation by hackers. These weaknesses can have severe consequences, including financial losses, damage to reputation, or national security breaches.
