On March 5, an international law enforcement operation shut down one of the world’s largest cybercrime forums, LeakBase. The operation was led by the Federal Bureau of Investigation (FBI) and Europol, with support from authorities across 14 countries.
Operating since 2021, LeakBase had become a major marketplace for cybercriminal activity. The platform was widely used for trading stolen databases, leaked data, stealer logs, hacking tools, and compromised credit card information. According to law enforcement officials, the forum had more than 142,000 registered members.
Authorities Seize Platform Data
During the operation, authorities not only seized the forum’s infrastructure but also collected extensive evidence. This includes user accounts, forum posts, private messages, credit card details, and IP logs. The seized data will support ongoing criminal investigations and international cooperation efforts.
Law enforcement agencies have also taken control of LeakBase’s two main domains and replaced them with official seizure notices to prevent further criminal activity.
Cybercrime and Cryptocurrency Transactions
As cybercrime marketplaces expand, criminals increasingly rely on cryptocurrency for payments. Stolen data, hacking services, and fraud tools are often traded using digital assets, allowing criminals to operate across borders with greater anonymity.
However, the transparency of blockchain transactions also creates opportunities for investigators and compliance teams to track suspicious fund flows linked to illegal activities.
How KYT Identifies High-Risk Transactions
In the digital asset industry, KYT (Know Your Transaction) systems play a key role in monitoring blockchain transactions and identifying suspicious activity in real time. KYT solutions analyze transaction patterns, wallet behavior, and risk indicators to detect connections with illicit markets or criminal networks.
Solutions such as Trustformer KYT continuously monitor blockchain addresses and transaction flows, flagging funds associated with cybercrime forums, data breach marketplaces, or other high-risk entities. This enables exchanges and financial platforms to identify suspicious funds before they enter their systems.
As global law enforcement continues to crack down on cybercrime infrastructure, on-chain monitoring and KYT risk management are becoming essential components of digital asset security and compliance.
