Russian state-sponsored hackers are conducting a global phishing campaign targeting Signal and WhatsApp accounts of government officials, military personnel, and journalists by impersonating support chatbots to steal verification codes and abuse linked device features. The campaign exploits legitimate security functions rather than technical vulnerabilities, allowing attackers to access encrypted messages and group chats after compromising individual accounts.
