Intelligence Summary
The FBI and CISA report a phishing campaign aimed at Signal users has shifted to stealing Backup Recovery Keys. If the keys are obtained, attackers can recover victims’ historical Signal messages. The campaign is linked to Russian intelligence services. This increases the risk of message disclosure even when Signal itself is protected by strong encryption. Users should treat Signal key prompts and recovery flows as high-risk and avoid following unsolicited links or instructions.
Recommended Action
Prioritize immediate review, validate exposure, and patch or mitigate affected systems.
