Brians Club .cm was an underground website known for selling stolen credit card information. Operating on the dark web, it facilitated illegal transactions by offering cybercriminals access to large quantities of compromised financial data, often acquired through data breaches or phishing attacks. The platform allowed users to purchase and use these stolen details for fraudulent activities, such as unauthorized purchases and identity theft. BriansClub.cm became a significant player in the dark web's illicit economy until law enforcement agencies successfully seized much of its data, shutting down the operation and disrupting its criminal activities.
