The FBI, along with the Cybersecurity and Infrastructure Security Agency (CISA), has issued a strong warning to Americans, advising them to avoid sending text messages between iPhones and Android devices. Instead, they recommend switching to fully encrypted messaging apps.
This advisory follows a series of cyberattacks attributed to the Salt Typhoon hacking group, linked to China’s Ministry of Public Security. The group’s attacks on U.S. telecommunications networks have raised alarms about vulnerabilities in critical communication systems.
CISA’s Jeff Greene highlighted the importance of encryption as a primary defense against cyber threats. He noted that even if data is intercepted, encryption ensures it remains unreadable.
Cross-platform Texts at Risk
While messages sent between iPhones using iMessage or between Android devices using Google Messages are encrypted, communication between the two platforms is still vulnerable. The lack of end-to-end encryption in Rich Communication Services (RCS), which replaces SMS, is a major concern, with no clear timeline for a solution.
Both Google and Apple have acknowledged this issue, but progress has been slow despite promises to implement RCS encryption. Until encryption is available for RCS, security experts advise avoiding traditional text messaging for sensitive communications.
The Rise of Encrypted Apps
In light of these security concerns, officials are urging the use of encrypted messaging apps like Signal, WhatsApp, and Facebook Messenger. These platforms offer end-to-end encryption for both texts and voice calls, ensuring privacy and security across devices.
“Encryption is your friend,” Jeff Greene emphasized. “When data is encrypted, it becomes nearly impossible for adversaries to access it.”
Broader Implications
The warning highlights the increasing cybersecurity risks from state-sponsored attacks. A joint alert from the FBI, CISA, NSA, and other Five Eyes intelligence agencies underscored the ongoing threat to U.S. networks, urging individuals and businesses to implement stronger security measures.
Coincidentally, Apple’s upcoming iOS 18.2 update will allow users to change their default messaging app from iMessage, making it easier for them to switch to more secure platforms.
Until encryption becomes standard for all text-based communication, experts recommend using apps like Signal or WhatsApp as the default for cross-platform messaging to protect sensitive information from cyber threats.
