An international law enforcement operation led by the U.S. Federal Bureau of Investigation and Europol has taken offline LeakBase, a major cybercrime forum used to trade stolen data and malicious tools. At the time of the action the site reportedly had more than 142,000 registered members and over 215,000 messages.
According to the FBI, agents seized forum user accounts, public posts, credit card details, private messages and IP logs as evidence. The coordinated takedown occurred March 3–4 and involved synchronized measures across 14 countries. After the operation, authorities replaced the site with seizure banners, issued prevention notices to members, and collected additional forensic material.
Search warrants and arrests associated with the disruption were executed in the United States, Australia, Belgium, Poland, Portugal, Romania, Spain and the United Kingdom. U.S. Department of Justice officials described the dismantlement as a significant disruption of an international platform criminals used to buy and sell stolen personal, banking and account credentials.
LeakBase’s public listings did not prominently feature cryptocurrency accounts, but law enforcement noted links in the broader ecosystem. Its predecessor, RaidForums, which was shuttered in 2022, previously hosted a large leak that included roughly 272,000 detailed personal records tied to users of crypto hardware wallet firm Ledger.
The takedown comes amid a wider rise in leaked and exposed crypto-related data over the past year. Reported incidents include claims that criminals bribed overseas customer service contractors in May 2025 to access Coinbase systems and steal personal data; the leak of nearly 60,000 Bitcoin addresses tied to LockBit’s ransomware infrastructure after an affiliate panel breach; and a February dispute in which a trader known as TraderSZ said a former Revolut employee threatened to expose him and contact his family unless paid.
