FBI’s secure messaging apps warning urges Americans to switch to encrypted platforms as cyberattacks on communication networks grow.
In the wake of ongoing revelations about cyberattacks by Chinese-linked hacking group Salt Typhoon, the FBI has intensified its secure messaging apps warning, urging Americans to transition to encrypted platforms like WhatsApp, Signal, and Facebook Messenger. This update follows our earlier coverage, incorporating new developments, including proposed legislation aimed at strengthening U.S. telecommunications security.
01
of 07A Continued Call for Secure Messaging
The FBI’s latest advisory highlights the growing sophistication of Salt Typhoon’s cyber espionage campaign. This campaign has targeted U.S. telecommunications networks, compromising metadata and selecting private communications.
“Our previous warnings highlighted the vulnerabilities of unencrypted text messaging,” said an FBI spokesperson during a briefing today. “This new evidence further underscores the urgent need for Americans to adopt secure apps for all communications. Encryption is no longer optional; it is essential.”
CISA’s Jeff Greene also emphasized the importance of transitioning to encrypted communication: “Americans must prioritize secure messaging apps to counter the advanced threats we face. Platforms like Signal, WhatsApp, and Facebook Messenger provide the best defense against these ongoing attacks.”

of 07Proposed Legislation to Bolster Cybersecurity
In response to these threats, U.S. lawmakers have proposed the “Communications Security and Privacy Act,” introduced today to mandate encryption standards for telecommunications providers. This legislation seeks to improve cybersecurity practices and incentivize the adoption of secure messaging apps nationwide.
The proposed legislation follows last week’s classified Senate briefing on Salt Typhoon, where lawmakers learned of vulnerabilities in U.S. communications infrastructure. Bipartisan support for swift action has emerged, with Sen. Maria Cantwell stating, “This legislation ensures all Americans can rely on secure communication platforms, safeguarding both personal privacy and national security.”
03
of 07The Widening Threat of Salt Typhoon
Fresh intelligence reveals that Salt Typhoon’s operations are broader than previously reported, targeting government agencies, private companies, and individual users. The group exploits gaps in encryption to intercept sensitive communications, further exposing flaws in outdated systems like SMS and RCS (Rich Communication Services).
“The scale and sophistication of these attacks are unprecedented,” Greene said. “Hackers are exploiting the lack of encryption in cross-platform communication systems, and Americans must act now to secure their communications.”

of 07Apple, RCS, and Cross-Platform Security
Apple’s recent release of iOS 18.2, which allows iPhone users to change their default messaging app from iMessage, marks a significant shift in offering consumers more secure options. However, the lack of end-to-end encryption for RCS in cross-platform messaging remains a critical vulnerability.
While Google and the GSMA have promised to roll out encryption for RCS, no timeline has been confirmed, leaving millions of users exposed to potential cyberattacks.
05
of 07The FBI’s Expanded Recommendations
To mitigate the risks posed by these vulnerabilities, the FBI and CISA have expanded their recommendations:
- Switch to encrypted messaging apps: Platforms like WhatsApp, Signal, and Facebook Messenger now fully encrypt communications, providing robust protection.
- Avoid unencrypted cross-platform messaging: Until RCS encryption is fully implemented, users are advised to avoid communication between iPhones and Androids via SMS or RCS.
- Update devices regularly: Keeping smartphones and apps updated ensures protection against known vulnerabilities.
- Adopt secure collaboration tools: For organizations, encrypted platforms for internal communication are essential.

of 07Looking Ahead: Balancing Privacy and Security
The proposed legislation and expanded FBI guidance highlight a pivotal moment in the U.S.’s approach to cybersecurity. The focus on encryption represents a significant step forward, although challenges remain in balancing privacy with law enforcement access to data.
As Forbes notes, this shift underscores the FBI’s evolving stance on encryption, which it now frames as a necessary defense against increasingly sophisticated cyber threats. “Encryption isn’t just a feature; it’s a critical component of our digital security,” Greene reiterated.
07
of 07A Call to Action
The Salt Typhoon cyberattacks underscore the urgency of adopting secure communication practices. The FBI’s secure messaging apps warning is a clear call for individuals and organizations alike to take immediate action to protect their communications.
With legislation in motion and tech companies working to enhance encryption, the hope is that secure communication will soon become the standard rather than the exception. For now, the message from experts is clear: switch to secure messaging apps and stop using unencrypted systems.
