FBI warns of Russian Intelligence phishing campaign abusing Signal support services to target VIPs and high-value government and military targets — this is how to secure your account

The FBI has warned Russian Intelligence Services are posing as commercial messaging application support services in order to steal Backup Recovery Keys belonging to targets of high value in the military and government of the US, Europe, and Ukraine.

In a joint warning alongside the CISA and the Security Service of Ukraine (SSU), the FBI outlined the new phishing campaign which seeks to access messaging accounts in order to perform intelligence gathering of secret information.

Specifically, the FBI provided sample phishing lures targeting users of the Signal messaging app. If the hackers successfully lure a victim into sharing their Backup Recovery Key, they can access the account's message history, private and group messages, and fully take over the victim's account.
