KrebsOnSecurity reports that on average, stolen credit card data available at these underground forums is worth $500 per record, which explains why, even as banks roll out EMV terminals to reduce fraud risk in stores, such forums remain popular and attract many customers.

The Site’s Identity

Briansclub cm Dealer Data Breach serves as a stark reminder that cybercriminals are always searching for opportunities to exploit weaknesses in our digital systems, such as credit card data theft. Criminals may use stolen credit card details for any number of fraudulent activities and can damage victims’ credit scores for years afterward. Luckily, individuals and businesses alike can take steps to defend themselves from attacks like this one: first by employing strong passwords and two-factor authentication whenever interacting online systems; next by monitoring their credit scores regularly and reporting any suspicious activity to credit bureaus immediately.

One of the primary targets of this attack was BriansClub, an established website for purchasing and selling stolen credit card information, according to KrebsOnSecurity. This popular destination for cybercriminals seeking stolen cards or financial data offers various services and consistently supplies stolen card data to cybercriminals looking for quick profits – featuring even an image of security journalist Brian Krebs with its name being derived from his popular blog Krebs on Security!

Gemini Advisory, the New York firm that verified the data for KrebsOnSecurity, found that BriansClub’s most recently uploaded database of stolen card records included 26 million cards. Of these cards, roughly 21.6 million are estimated not to expire until after October 2019, giving criminals plenty of opportunity for cashout.

Gemini estimates that these resellers and buyers purchased approximately 9 million cards over the most recent batch added to BriansClub.

BriansClub stands out from its competition not only by offering an expansive selection of cards but also through its quality control and outstanding customer service, making it an attractive destination for criminals looking for card data they know will work in real life.

The Data Leak’s Impact

KrebsOnSecurity reviewed data shared by a source and discovered that BriansClub had been selling stolen credit card records online since 2015.

This website sells card records to criminals for use in various types of fraud, such as credit card theft in physical retail locations and online.

KrebsOnSecurity’s investigation of the stolen database reveals that its site began with only 1.7 million card records to sell in 2015, but business rapidly escalated each year thereafter – adding 2.89 million records in 2016, 4.9 million cards in 2017 and finally 9.2 million cards by 2018.

Total losses associated with stolen card data sold through this site have been estimated at an estimated $414 million, assuming each card record costs $500 to purchase from criminals.

KrebsOnSecurity believes it’s likely the site will continue operating with less card records for sale.

As well as cash theft, stolen card data can cause lasting harm to victims’ credit histories. Fraudulent transactions on victims’ cards may cause their accounts to close – further jeopardizing their ability to borrow for mortgages or cars in the future.
