FBI and Europol Dismantle Major Trojan-Based Malware Networks by Uninstalling Infected Machines

Trojans are malware disguised as legitimate files or software, relying on users to run them rather than exploiting technical flaws. Early examples like Zeus stole banking credentials and built botnets, while Emotet later evolved into a loader that rented access to other criminals, including ransomware gangs. In January 2021, Europol and Eurojust took control of Emotet's infrastructure and pushed an update that disconnected infected machines. In August 2023, the FBI's Operation Duck Hunt redirected Qakbot-infected computers and removed the malware from more than 700,000 machines, seizing about $8.6 million in cryptocurrency. Security experts advise avoiding enabling macros in unexpected documents, downloading software only from official sources, and running untrusted code in isolated environments.
