chosen brick

Chosen Brick is Windows-only spyware linked by the FBI, the UK's National Cyber Security Centre, and the Netherlands' AIVD to Iranian state cyber actors. According to the tagged coverage, the campaign does not rely on a Windows vulnerability or mass email; instead, attackers build trust over WhatsApp or Telegram and persuade a specific target to run a convincing fake application or document. Reported targets include dissidents, activists, and journalists in the United States, United Kingdom, and Netherlands. The tag page collects this advisory and related discussion for readers tracking the threat, its social-engineering tactics, and the public warnings issued in September.
