Iranian threat actor Nimbus Manticore (UNC1549) conducted a series of campaigns in early 2026 utilizing AppDomain Hijacking, SEO poisoning, and task hijacking to deploy the new MiniFast backdoor. The group demonstrated rapid toolset evolution, likely aided by AI-assisted development, targeting the aviation and software sectors across the US, Europe, and the Middle East.
Check Point Research identified Silver Dragon, a Chinese-nexus APT group likely affiliated with APT41, targeting organizations in Southeast Asia and Europe. The group utilizes public-facing server exploits and phishing to deploy custom loaders that establish persistence via AppDomain hijacking and service manipulation. These loaders deliver Cobalt Strike and a novel Google Drive-based backdoor called GearDoor.
