  Google's Threat Analysis Group (TAG) observed multiple Russia-aligned threat actors, including APT29 (Cozy Bear) and Sandworm, actively targeting Signal users. These campaigns primarily focused on stealing authentication material from Signal servers, likely to bypass Signal's robust encryption and gain access to user communications. Although Signal's server-side infrastructure was targeted, the attackers needed physical access to the device to complete the compromise, significantly limiting the attack's effectiveness. While Signal's encryption remains unbroken, the targeting underscores the lengths to which nation-state actors will go to compromise secure communications.

  In a comprehensive blog post titled "Multiple Russia-aligned threat actors actively targeting Signal Messenger," Google's Threat Analysis Group (TAG) details a concerted campaign by several Russian state-sponsored Advanced Persistent Threat (APT) groups to compromise the secure messaging platform Signal. These malicious activities, predominantly observed throughout 2022, focused on exploiting vulnerabilities and employing sophisticated tactics to gain access to user data and communications.

  The primary target of these attacks appears to be individuals associated with Ukrainian government entities and media organizations, highlighting the geopolitical context of this digital offensive.
