THE FBI has issued a public service announcement warning that Russian intelligence officers are targeting high-risk users on Signal by attempting to steal backup recovery keys. The campaign involves deception tactics where Russian cyber actors impersonate automated support accounts to lure victims into revealing their verification codes and account PINs. This access enables them to view past messages and potentially take control of the victims' accounts.
The FBI's warnings include security tips for Signal users, advising them not to share recovery keys and to always verify the authenticity of communications from CMA support services. This Russian campaign aligns with previous threats aimed at government and military officials.
