Description: Written by: Dan Black Google Threat Intelligence Group (GTIG) has observed increasing efforts from several Russia state-aligned threat actors to compromise Signal Messenger accounts used by individuals of interest to Russia's intelligence services. While this emerging operational interest has likely been sparked by wartime demands to gain access to sensitive government and military communications in the context of Russia's re-invasion of Ukraine, we anticipate the tactics and methods used to target Signal will grow in prevalence in the near-term and proliferate to additional threat actors and regions outside the Ukrainian theater of war.

In anticipation of a wider adoption of similar tradecraft by other threat actors, we are issuing a public warning regarding the tactics and methods used to date to help build public awareness and help communities better safeguard themselves from similar threats. We are g...
