A spyware investigator exposed Russian government hackers trying to hijack Signal accounts

AI-summarised brief · reviewed before publication

Security researcher Donncha Ó Cearbhaill, who heads Amnesty International's Security Lab, was targeted by hackers attempting to hijack his Signal account. The hackers impersonated Signal security support, warning of suspicious activity and asking for a verification code. Ó Cearbhaill recognized the attempt as a phishing scam and decided to investigate further. He discovered that the attack was likely part of a wider campaign targeting over 13,500 Signal users, blamed on Russian government spies. The hackers used a system called "ApocalypseZ" to automate the attack, targeting multiple people at once.

💡 Why It Matters

  • · The Russian government's hacking campaign targeting Signal users raises concerns about the vulnerability of secure communication platforms.
  • · The fact that hackers were able to compromise high-profile politicians and journalists suggests a sophisticated and widespread effort to disrupt secure communication channels.
