One of the biggest black market merchants for stolen credit cards on the Internet, the Briansclub, was itself a victim of a cyber attack this August.
According to security expert Brian Krebs the entire Briansclub database was uncovered. Millions of data could be seized and identified, blocked and re-issued with the help of the responsible financial institutions.
The Briansclub has hacked online and stationary retailers for a total of four years. Year after year, large quantities of stolen cards were uploaded. In 2019 alone, almost eight million credit cards were collected. The security company Flashpoint estimates the value of the cards offered for sale at around 414 million US dollars. The online black market retailer has already sold over nine million stolen credit cards and earned 126 million dollars from them in Bitcoin.
