Carding Mafia 2021

In March 2021 the Carding Mafia underground forum suffered a significant data breach. The incident led to the exposure of sensitive user information including email addresses usernames IP addresses and salted MD5 password hashes. The breach impacted approximately 297000 forum members who were involved in the trade of stolen financial data. The forum which was a hub for cybercriminal activity and credit card fraud experienced another security incident later in December 2021 but the March data remains the primary public leak documented by security researchers.
