International Law Enforcement Dismantles Major Cybercrime Forum LeakBase
A coordinated international law enforcement operation, led by the U.S. Department of Justice and Europol, dismantled LeakBase, one of the world's largest online forums for trading stolen data and cybercrime tools. Enforcement actions, including arrests and house searches, began on March 3, 2026, across 14 countries. The forum, active since 2021, had over 142,000 members and facilitated the sale of leaked databases, including credit card numbers, banking information, usernames, and passwords. The operation seized LeakBase's data and domains, replacing them with law enforcement splash pages.
