Global Takedown of "LeakBase": The World's Largest Stolen Data Market Dismantled in 2026

In a landmark achievement for international law enforcement, a coordinated 14-country effort codenamed "Operation Leak" successfully dismantled LeakBase on March 4, 2026. Once the world’s most prominent hub for buying and selling stolen credentials, financial data, and hacking tools, the forum's shutdown marks a significant blow to the global cybercrime ecosystem.

Case Details & Operation Highlights (March 2026):

• The Scale: LeakBase boasted over 142,000 registered users, 32,000 posts, and more than 215,000 private messages before its seizure.

• The Crackdown: Between March 3 and 4, law enforcement executed approximately 100 enforcement actions worldwide, including arrests, house searches, and "knock-and-talk" interventions.

• Lead Agencies: Coordinated by Europol and led by the U.S. FBI, the operation involved authorities from Australia, Belgium, Germany, Poland, Romania, Spain, and the UK, among others.

• Technical Seizure: Authorities seized the forum's database and its primary domains (including leakbase.la and leakbase.ws), replacing them with an official law enforcement splash page.

A Goldmine of Evidence

Unlike previous takedowns, Operation Leak focused on capturing the forum’s entire backend. The FBI confirmed the seizure of:

• User Accounts & IP Logs: Directly deanonymizing tens of thousands of members.

• Private Messages & Transaction Logs: Exposing the inner workings of data trades and financial fraud.

• Credit Details: Secured for evidentiary purposes in future prosecutions.

Strategic Impact

LeakBase had risen to power following the 2022 and 2023 shutdowns of its predecessors, RaidForums and BreachForums. One notable internal rule of the forum was the prohibition of selling Russian data, a tactic likely meant to avoid local scrutiny.

Official Statement (Assistant Attorney General Tysen Duva):

"The takedown of this cyber forum disrupts a major international platform that cybercriminals use to profit from the theft of sensitive personal, banking, and account credentials."

What Comes Next?

The operation has now entered a "prevention phase." Law enforcement is actively sending deterrence messages to forum members and using the seized data to track down high-value targets. For the average citizen, this takedown is a reminder of the vital importance of Multi-Factor Authentication (MFA) and rotating passwords, as the data circulating on such forums remains a threat even after the platform is gone.
