The FBI and CISA issued a joint PSA warning of a global phishing campaign by the Russian Intelligence Services that targets Commercial Messaging Applications to compromise individual accounts and steal private communications. The actors use social engineering and abuse of linked-device features—especially against Signal users—to take over accounts, monitor messages, infiltrate group chats, and conduct follow-on phishing, prompting agencies to urge stronger personal security. #RussianIntelligenceServices #Signal
