Law Enforcement Seizes LeakBase Forum, 142,000 Users

Europol, the FBI and international partners seized LeakBase — an open-web forum with ~142,000 users trading stolen credentials, stealer logs and financial data — and preserved accounts, posts, private messages and IP logs during 'Operation Leak' across 14 countries targeting 37 top users. Action: assume credential exposure—reset and monitor accounts, enforce MFA, hunt for suspicious logins and review transaction logs.
