Thu Dec 05 14:30:00 UTC 2024: ## FBI and CISA Urge Americans to Adopt Encrypted Messaging Amidst Widespread Chinese Cyberattacks

**Washington D.C.** – Following revelations of a large-scale Chinese cyber espionage campaign targeting US telecommunications networks, the FBI and Cybersecurity and Infrastructure Security Agency (CISA) are urging American citizens to utilize encrypted messaging and calls. The campaign, attributed to the Salt Typhoon group linked to China’s Ministry of Public Security, has reportedly compromised multiple telecom companies, potentially accessing call and text metadata, and in some cases, the content of communications from government and political figures.

A senior FBI official confirmed the ongoing investigation, stating that the campaign is “broad and significant,” and that the bureau began investigating in the spring and summer of this year. While the FBI emphasizes that widespread call and text content was not stolen, the theft of metadata and limited access to content highlights the vulnerability of unencrypted communications.

CISA’s Jeff Greene echoed the FBI’s concerns, strongly recommending that Americans utilize encrypted communication apps for all messages and calls. This warning underscores the lack of end-to-end encryption in cross-platform Rich Communication Services (RCS), the successor to SMS, which leaves messages sent between iPhones and Android devices vulnerable.

The news has prompted a strong political response. A classified briefing for all senators on the Salt Typhoon attacks has resulted in vows of action, and a Senate Commerce subcommittee will hold a hearing on December 11th to address the security risks and review best practices.

The FBI’s recommendation emphasizes “responsible encryption,” which allows for lawful access to user data through official requests. This clarifies that while platforms like Signal and WhatsApp, with their strong end-to-end encryption, are recommended for enhanced security, they are not explicitly discouraged.

The timing of this warning is particularly noteworthy, coinciding with Apple’s rollout of RCS support and the growing adoption of encrypted messaging apps. The vulnerabilities exposed by the Chinese hacking highlight the urgent need for increased security measures in personal and national communications. Experts advise users to prioritize fully encrypted platforms like WhatsApp and Signal for all cross-platform messaging and calls until RCS implements full end-to-end encryption.
