The Critical Flaws in SMS, MMS, and RCS Protocols
In 2024, telecom network vulnerabilities have become a major threat to both governmental and commercial communications. These weaknesses in protocols such as SS7 and Diameter highlight the urgency of addressing telecom vulnerabilities this year with robust encryption measures.
While SMS, MMS, and RCS remain widely used, their reliance on outdated and vulnerable protocols makes them prime targets for exploitation. The FBI and CISA identified the following key risks:
- Interception of Messages: Unencrypted SMS and MMS are transmitted in plaintext, making interception relatively easy for cybercriminals.
- SIM Swapping Attacks: Threat actors take control of victims’ phone numbers, granting them access to sensitive accounts secured by SMS-based two-factor authentication (2FA).
- Telecom Infrastructure Exploits: Weaknesses in protocols such as SS7, Diameter, and RCS allow adversaries to compromise entire networks, intercepting metadata, call records, and live communication streams.
Related Threats
Protocols like SS7, originally designed in the 1970s for 2G and 3G networks, were never built with modern security standards in mind. Vulnerabilities in SS7 and related protocols, including Diameter (4G/5G) and SIP (VoIP), further exacerbate the risks of telecom-based attacks.

Salt Typhoon: The Scope of Cyberespionage
Salt Typhoon’s impact on global telecom networks highlights the importance of securing sensitive data with sovereign-grade encryption solutions. The Salt Typhoon campaign demonstrates the global impact of cyberattacks on telecom networks. By targeting operators in the U.S., Europe, and other strategic regions, Salt Typhoon underscores the critical need for sovereign security solutions to protect sensitive communications worldwide.
State-Sponsored Cyber Attacks
Salt Typhoon, a Chinese state-affiliated group, exemplifies the modern-day cyberespionage threat. This group bypasses traditional endpoint security measures by directly targeting telecom infrastructure. Their tactics include:
- Exploiting Zero-Day Vulnerabilities: Leveraging unpatched software flaws in telecom systems to gain unauthorized access.
- Misconfiguration Exploits: Exploiting poorly configured core network components, enabling large-scale data extraction.
- Intercepting Call Detail Records (CDRs): Accessing metadata, live call data, and surveillance logs.
Salt Typhoon’s activities have compromised sensitive data involving high-ranking officials, security agencies, and critical businesses. The breach extends beyond the U.S., affecting telecom operators in France (SFR), Spain (Telefónica), and other global entities.
Global Implications
The breach highlights the structural vulnerabilities of international telecom networks. The PRC uses these intrusions to:
- Gather Strategic Intelligence: Inform military and economic policies.
- Undermine U.S. and Allied Credibility: Compromise allied infrastructure, including NATO and Five Eyes.
- Proliferate Cyber Tactics: Inspire other state-sponsored actors to replicate similar attacks.
These vulnerabilities underline the urgent need for coordinated international efforts to mitigate risks and safeguard sensitive communications.
International Cooperation to Combat Telecom Threats
The response to Salt Typhoon underscores the importance of global cooperation. Agencies from the Five Eyes alliance (USA, UK, Canada, Australia, and New Zealand) and European counterparts are actively working together to mitigate risks, share intelligence, and strengthen cybersecurity defenses globally.
Regulatory Responses to Salt Typhoon: FCC’s Call to Action
The Federal Communications Commission (FCC) has taken decisive steps to strengthen the resilience of telecommunications infrastructure following the Salt Typhoon cyberattack. This attack, confirmed on December 4, 2024, compromised sensitive systems in at least eight U.S. telecom companies and exposed vulnerabilities in critical infrastructure.
Key FCC Measures:
- Cybersecurity Obligations:
- Telecommunications carriers must comply with Section 105 of the Communications Assistance for Law Enforcement Act (CALEA) to secure their networks.
- Legal obligations extend beyond equipment to include network management practices.
- Compliance Framework:
- Annual certification for cybersecurity risk management plans.
- Expanded obligations for all communications providers to implement robust security measures.
- National Security Focus:
- Recognizing the critical role of telecom networks in defense, public safety, and economic systems, the FCC’s actions aim to build resilience against future cyberattacks.

Salt Typhoon: A Case Study in Telecom Exploitation
The Salt Typhoon attack is a stark reminder of how state-sponsored actors bypass traditional security measures to target telecom infrastructure directly. Operating under the guise of Earth Estries—a Chinese cyberespionage group—their tactics reveal a sophisticated approach to large-scale data theft and network manipulation.
Tactics and Techniques:
- Zero-Day Exploits:
- Unpatched vulnerabilities in core telecom systems.
- Misconfigurations:
- Exploiting poorly configured network components to gain unauthorized access.
- Interception of Call Detail Records (CDRs):
- Accessing metadata, live communications, and surveillance logs without targeting individual devices.
Global Reach:
Salt Typhoon has impacted major telecom operators globally, including:
- U.S. carriers (AT&T, Verizon, T-Mobile).
- European providers like SFR (France) and Telefónica (Spain).
Protocol Vulnerabilities: A Gateway for Cyber Espionage
While Salt Typhoon focuses on telecom infrastructure, vulnerabilities in SS7, Diameter, and related protocols serve as entry points for cyber adversaries.
Key Protocol Risks:
- SS7 (Signaling System 7):
- Designed for 2G/3G networks, SS7 was never intended for secure communication, making it vulnerable to message interception and location tracking.
- Diameter Protocol:
- Used in 4G/5G networks, Diameter faces similar risks, including denial-of-service attacks and message tampering.
- RCS (Rich Communication Services):
- A modern SMS replacement, RCS still lacks robust encryption, leaving it open to interception and spoofing.
