From a Europol press release:

A major online forum for stolen data has been dismantled following an international operation coordinated by Europol.

The forum, known as LeakBase, had established itself as a central hub in the cybercrime ecosystem, specialising in the trade of leaked databases and so-called “stealer logs” – archives of stolen credentials harvested through infostealer malware. Accessible on the open web and operating in English, the platform combined elements of a forum and discussion board, enabling cybercriminals to buy, sell and exchange compromised data.

Between 3 and 4 March, coordinated actions across multiple jurisdictions severely disrupted the forum’s operations and targeted its most active users.

On 3 March, law enforcement authorities carried out coordinated enforcement actions across multiple jurisdictions, including arrests, house searches and “knock-and-talk” interventions. Around 100 enforcement actions were conducted worldwide, including measures against 37 of the most active users of the platforms.

On 4 March, authorities moved to the technical disruption phase, seizing the forum’s domain and replacing it with a law enforcement splash page.

The operation now enters a prevention phase aimed at deterring further criminal activity and raising awareness of the consequences of engaging in cybercrime.
