Russian hackers are impersonating Signal support to access government messages, highlighting ongoing cyber espionage risks.
German federal prosecutors have been investigating suspected cyberattacks on Signal accounts since mid-February 2026. Around 300 political figures and journalists have been targeted through phishing campaigns linked to Russian state hackers. The attacks involve fake Signal support messages that enable hackers to access private chats and data. Germany has not officially attributed the attacks to Russia, but authorities warn of ongoing threats to political and civil service accounts.
