One of the largest black market websites, BriansClub, which specializes in the sale of credit card data acquired by hackers, has been compromised. The data breach was initially revealed by security expert Brian Krebs, who claims that the hackers obtained information from more than 26 million credit cards.
According to experts, about 30% of the cards sold on the black market are made up of the entire number of stolen cards that were stolen from BriansClub.
One of the biggest online marketplaces for purchasing credit card data has actually been hacked. reads the article that Brian Krebs authored. More than 26 million credit and debit card records from online and brick-and-mortar stores over the course of four years, including nearly 8 million records added to the store in 2019 alone, are included in the data stolen from BriansClub.
According to Krebs, a source gave him access to a file last month that contained the whole BriansClub database. The archive had information on both historically and currently for sale cards.
Nearly eight million records uploaded in 2019 alone are among the data taken from brick-and-mortar stores during the previous four years that are included in the collection.
Historical data from the archive demonstrates the site’s explosive expansion; in 2015, it added merely 1.7 million card records for sale; in 2016, it added 2.89 million stolen cards; in 2017, it added 4.9 million cards; and in 2018, it added 9.2 million cards. About 7.6 million new cards were added to BriansClub between January and August of this year.
As a reseller or affiliate who receives a commission from each sale, BriansClub works as a broker of credit card information obtained by other online criminals.
Since 2015, BriansClub has generated sales of $126 million for the website and its distributors by selling almost 9.1 million stolen credit cards.
“It’s difficult to determine how many of the roughly 26 million cards being sold at BriansClub are still valid, but the closest estimate is that there are unsold cards have expiration dates in the future — indicates more than 14 million of them could still be valid.” states Krebs.
The administrator of BriansClub acknowledged that the data centre that houses his website had been compromised earlier this year, according to a follow-up post written by Krebs. Although several sources indicated they are still on sale at BriansClub, the administrator claimed that stolen data had been taken out of the inventories of the stores. BriansClub was compromised by “a very established ne’er-do-well who uses the handle “MrGreen” and operates a competing card shop by the same name,” said Krebs, the moderator of the Russian cybercrime forum Verified.
