Intelligence Summary
The FBI and CISA updated a warning about Russian intelligence phishing campaigns aimed at Signal users. The guidance says attackers now try to obtain Signal Backup Recovery Keys from victims. Once the key is provided, the attacker can restore the account and access private and group message histories. The same recovery key may continue to work, enabling continued account compromise. Signal users should be cautious with recovery-key prompts and follow official guidance to protect accounts.
Recommended Action
Review affected assets, schedule urgent remediation, and monitor related indicators.
