US Department of Justice and Europol seize LeakBase hacker forum with 142,000 members, recovering stolen data from major breaches and making multiple arrests across 14 countries.
The U.S. Department of Justice and Europol have dismantled LeakBase, a major cybercrime forum operating across 14 countries, in a coordinated operation that resulted in the seizure of the website and multiple arrests.

According to official statements, authorities seized "users' accounts, posts, credit details, private messages, and IP logs" from 142,000 members who had posted approximately 215,000 messages on the platform. The forum, which operated in English to attract a global audience, served as a marketplace for cybercrime tools and stolen account credentials.
The seizure banner now displayed on the former LeakBase website indicates the operation took place between March 3 and 4 at Europol's headquarters in The Hague. The takedown represents one of the largest hacker forum disruptions in recent years, targeting a platform that authorities say facilitated numerous high-profile cyberattacks.
Scale of the Operation
The investigation revealed that LeakBase contained data from multiple major breaches, including "hundreds of millions of account credentials." Seized information encompassed credit and debit card numbers, banking account and routing information, along with "sensitive business and personally identifiable information."
Beyond the digital takedown, the operation included physical enforcement actions. Europol reports that authorities conducted 100 policing actions targeting 37 of the most active users on the platform. These actions included arrests, house searches, and "knock-and-talk" interventions across participating jurisdictions.
International Cooperation
The operation spanned multiple continents, with participating countries including the United States, eight Europol member states, Australia, Canada, Malaysia, the United Kingdom, and Kosovo. This level of international coordination demonstrates the growing sophistication of cybercrime enforcement efforts.
Cybercrime's Growing Threat
The LeakBase takedown comes amid escalating concerns about cybercrime's economic impact. Current estimates project cybercrime will cost the global economy $10.5 trillion annually by 2025. To put this in perspective, if cybercrime were a country, it would rank as the world's third-largest economy by GDP, trailing only the United States and China.
The Challenge Ahead
Law enforcement officials acknowledge that operations like this represent an ongoing challenge. As authorities successfully dismantle major platforms, cybercriminals often migrate to new forums or develop more sophisticated methods. The increasing adoption of AI-powered attack automation is expected to make future enforcement efforts even more complex.
The LeakBase case highlights both the progress being made in international cybercrime enforcement and the persistent challenges that remain. While authorities can disrupt major operations, the underlying economic incentives driving cybercrime continue to evolve, requiring constant adaptation of investigative and enforcement strategies.
