The FBI has shut down one of the internet’s most notorious cybercrime hubs, the LeakBase forum, in a major international operation that spanned 14 countries. This forum, which allowed hackers to trade stolen data, exploits, and cybercrime tools, has been permanently taken offline, marking a significant victory for global law enforcement in the fight against digital crime.
Coordinated Global Action Against Cybercrime
On March 3 and 4, the FBI executed a multi-step operation targeting LeakBase, seizing its domains, posting official seizure banners, and notifying forum members of the action. This initiative, part of “Operation Leak”, involved police forces, investigators, and intelligence units across Australia, Belgium, Poland, Portugal, Romania, Spain, the United Kingdom, and the United States.
Authorities executed search warrants, carried out arrests, and conducted interviews targeting both the administrators and active users of the forum. The seized domains now display a notice declaring, “This website has been seized by the Federal Bureau of Investigation (FBI) as part of an international law enforcement operation,” emphasizing that all data, including IP logs, private messages, and account details, will serve as evidence in ongoing investigations.
Technical Disruption and Evidence Preservation
LeakBase’s servers and domain infrastructure have been redirected to the FBI’s seizure nameservers (ns1.fbi.seized.gov and ns2.fbi.seized.gov), ensuring full control over the forum’s content. Europol reported that approximately 100 enforcement actions were carried out worldwide, including targeting 37 of the forum’s most active users. The operation moved into a “technical disruption phase” after these initial actions, effectively preventing further access while signaling a strong deterrent message to the cybercrime community.
LeakBase’s Rise and Function
Founded in 2021 with backing from the ARES threat group, LeakBase emerged after the closure of previous hacker forums like Breached. It quickly gained over 142,000 members by offering free registration, access to sensitive databases, exploit marketplaces, and guides on hacking techniques, cryptography, social engineering, and operational security. The forum also featured an escrow system, making it a trusted platform for illicit transactions.
LeakBase followed in the footsteps of RaidForums (disrupted in 2022) and BreachForums (shut down in 2023), both of which were significant cybercrime marketplaces. The founder of BreachForums was convicted and sentenced in 2025, highlighting the global trend of law enforcement taking increasingly sophisticated action against these digital crime networks.
What Undercode Say:
The shutdown of LeakBase is more than a symbolic victory—it highlights the evolution of global cybercrime enforcement. Coordinated efforts across multiple jurisdictions demonstrate that law enforcement agencies are increasingly capable of disrupting international digital criminal ecosystems. The scale of the operation—100 enforcement actions in multiple countries—also indicates a shift from reactive takedowns to proactive, intelligence-driven interventions.
LeakBase’s infrastructure, which included forums, databases, private messaging, and an escrow system, mirrors legitimate online marketplaces in structure, showing how sophisticated cybercrime operations have become. The forum’s ability to attract 142,000 members in just two years demonstrates both the demand for stolen data and the resilience of criminal networks despite repeated takedowns.
This operation also underscores the critical role of international collaboration. Cybercrime does not respect borders, and platforms like LeakBase thrive on anonymity and decentralized networks. By coordinating arrests, technical seizures, and evidence preservation across 14 countries, authorities send a clear message: cybercriminal hubs can no longer operate with impunity.
The preventive phase of the operation, aimed at raising awareness and deterring future participation, is equally crucial. Forums like LeakBase often migrate to alternative platforms after takedowns, but coordinated legal and technical disruption makes it increasingly risky for cybercriminals to rebuild at scale.
This case also reflects the changing tactics of cybercrime groups. LeakBase’s focus on education and community-building for hackers, alongside monetization, illustrates a hybrid model: forums are not only marketplaces but also incubators for skill-sharing, making law enforcement responses more complex.
Ultimately, the seizure of LeakBase illustrates an ongoing “cat-and-mouse” dynamic between law enforcement and cybercriminals. While the technical tools and illicit services evolve, the coordinated approach of agencies like the FBI and Europol demonstrates that global policing of digital crime is becoming more sophisticated, targeted, and deterrent-oriented.
Fact Checker Results:
✅ LeakBase forum seized by the FBI – confirmed.
✅ Operation involved 14 countries and 100 enforcement actions – verified by Europol.
✅ Forum content preserved for evidentiary purposes – official FBI seizure notice confirmed.
Prediction:
🚨 The takedown of LeakBase will likely trigger the emergence of smaller, more encrypted or invite-only cybercrime forums.
🔐 Law enforcement is expected to increasingly focus on intelligence-led operations, targeting infrastructure and key actors before forums gain significant traction.
💡 Future cybercrime marketplaces may adopt stronger decentralization, encryption, and anti-detection measures, making the next generation of takedowns more technically challenging.
