FBI Sounds Alarm Over Russian Intelligence Signal Phishing

The FBI issued a PSA saying multiple clusters of Russian intelligence actors are using targeted phishing—masquerading as messaging-app support or chatbots—to elicit Signal backup recovery keys, verification codes, and PINs from high-risk users (government officials, military, journalists and Ukrainian officials), enabling account takeover and access to historical messages; the advisory includes mitigation guidance such as never sharing codes or backup keys and regenerating recovery keys if compromised.
