The FBI and the Cybersecurity and Infrastructure Security Agency (CISA) have issued a warning regarding ongoing cyberattacks by the People's Republic of China (PRC) targeting U.S. telecommunications companies. These attacks have reportedly compromised networks at several major providers, including AT&T, Lumen Technologies, and Verizon, with the intent to steal customer call records and private communications, particularly of individuals involved in government or political activities. The warning follows earlier reports of a China-linked operation known as Salt Typhoon. Experts emphasize the need for heightened awareness and proactive measures against such threats, noting that the PRC's cyber activities are not limited to the U.S. but are a global concern. Security professionals recommend that organizations ensure their network traffic is encrypted and reconsider the use of SMS-based multi-factor authentication due to vulnerabilities associated with mobile network providers. The situation underscores the importance of collaboration with CISA for organizations that may be targeted by foreign intelligence agencies.
