The U.S. and Europol Dismantle One of the World’s Largest Hacker Forums

On March 3 and 4, 2026, law enforcement agents and officers in fourteen countries, including the United States (U.S.), took coordinated actions against LeakBase and its users in an initiative hosted by Europol. The participating countries shut down LeakBase, seized its data and two of the forum’s domains, posted seizure banners on the LeakBase sites, transmitted prevention messages to LeakBase members, and collected additional evidence. Law enforcement executed search warrants, made arrests, and undertook interviews in the U.S., Australia, Belgium, Poland, Portugal, Romania, Spain, and the United Kingdom (UK).
