FBI, CISA Warn Russian Hackers Are Targeting High-Value Individuals Through Signal

The FBI and CISA warn of a widespread Russian intelligence-led phishing campaign that compromises Signal accounts by tricking victims into surrendering SMS verification codes or scanning malicious QR codes, enabling account takeover and covert access to messages and contacts; thousands of accounts and high-value targets (government officials, military, journalists) are reportedly affected, and the agencies recommend strict account hygiene and device audits.
