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. To illustrate the magnitude and gravity of this issue, we have compiled statistics based on our web research:

Security Vulnerabilities in Emails

Emails serve as a central vector for cyberattacks, representing a significant portion of security incidents, with up to 91% of reported incidents, as per cybermalveillance.gouv.fr. 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.

  • Protocols: Communication protocols, like Internet Protocol (IP), Simple Mail Transfer Protocol (SMTP), Signaling System 7 (SS7), and Rich Communication Services (RCS), can contain security vulnerabilities. These vulnerabilities enable hackers to intercept, modify, or spoof communications on the network. For instance, an SS7 vulnerability allows hackers to eavesdrop on phone calls or read SMS messages on a cellular network.
  • Services: Network services, such as messaging, cloud, streaming, or payment services, possess their own vulnerabilities.
