“BriansClub,” one of the largest underground stores for buying stolen credit card data, has itself been hacked. The data stolen from BriansClub encompasses more than 26 million credit and debit card records taken from hacked online and brick-and-mortar retailers over the past four years, including almost eight million records uploaded to the shop in 2019 alone.
The leaked data shows that in 2015, BriansClub added just 1.7 million card records for sale. But business would pick up in each of the years that followed: In 2016, BriansClub uploaded 2.89 million stolen cards; 2017 saw some 4.9 million cards added; 2018 brought in 9.2 million more.
Between January and August 2019 (when this database snapshot was apparently taken), BriansClub added roughly 7.6 million cards.
Most of what’s on offer at BriansClub are “dumps,” strings of ones and zeros that — when encoded onto anything with a magnetic stripe the size of a credit card — can be used by thieves to purchase electronics, gift cards and other high-priced items at big box stores.
