The FBI has issued a warning about phishing campaigns conducted by cyber actors linked to the Russian Intelligence Services (RIS), which target commercial messaging applications (CMAs). These actors have compromised numerous individual accounts, focusing on individuals with significant intelligence value, such as U.S. government officials and journalists, without breaching the encryption of the applications. The campaigns have allowed unauthorized access to private messages, contact lists, and the ability to send deceptive messages. Users of CMAs, especially Signal, are particularly targeted. The phishing tactics involve disguising messages as communications from automated CMA support, leading victims to click malicious links or provide sensitive information. To mitigate risks, users are advised to enhance their cybersecurity measures, remain vigilant, and follow best practices such as scrutinizing links, verifying group chats, and reporting suspicious activity to the Internet Crime Complaint Center or local authorities.
