When Card Shops Play Dirty, Consumers Win

Summary: BriansClub, described as one of the largest underground shops for stolen credit and debit cards, was hacked and its database of 26 million cards was shared with banking industry security contacts; the data covered cards added between mid-2015 and August 2019. The administrator of the Verified cybercrime forum said the hack was carried out by a card shop operator using the nickname "MrGreen" who runs a competing shop, and the leaked database showed BriansClub sold roughly 9.1 million stolen credit cards for about $126 million in sales over four years.

What's compelling: Experts cited in the article estimate the cards leaked from BriansClub represent almost 30 percent of the cards on the black market today, and the shop's administrator disputes that the exposed cards were pulled from sale even as sources confirmed some were still being offered.
