Group-IB, a Singapore-based cybersecurity company that specializes in preventing cyberattacks, has detected that a huge database holding more than 1.3 million credit and debit card records of mostly Indian banks’ customers was uploaded to Joker’s Stash on October 28. The underground market value of the database is estimated at more than $130 million.
The database under the name “INDIA-MIX-NEW-01” (full name: “ INDIA-MIX-NEW-01 (fresh skimmeD INDIA base): INDIA MIX TR1+TR2/TR2, HIGH VALID 90-95%, uploaded 2019-10-28 (NON-REFUNDABLE BASE”) has been on sale on one of the most notorious underground card shops, Joker’s Stash, since October 28, 2019. The database contains only credit and debit card dumps Track 2, while its name suggests that it holds both Track 1 and Track 2 records. Track 2 dumps can be used to produce cloned cards for further cashing out.
According to the company’s press release, Group-IB’s Threat Intelligence team has analyzed all the card dumps from the database, more than 98% of which belong to Indian banks, 1% – to Colombian. More than 18% of the dumps in the database are related to a single Indian bank. The full database has more than 1.3 million records in total. It is one of the biggest single databases ever uploaded at once on underground markets and probably one of the most expensive ones. Every single dump in the set is valued at $100 which makes the total value of the database at least $130 million.
“It is true that big payment data leaks have happened before; however, the databases are usually uploaded in several smaller parts at different times,” said Ilya Sachkov, CEO and founder of Group-IB, Singapore-based cybersecurity company. “This is indeed the biggest card database encapsulated in a single file ever uploaded on underground markets at once. What is also interesting about this particular case is that the database that went on sale hadn’t been promoted prior either in the news, on card shop or even on forums on the dark net. The cards from this region are very rare on underground markets, in the past 12 months it is the only big sale of card dumps related to Indian banks. Group-IB’s Threat Intelligence customers have already been notified about the sale of this database. The information was also shared with proper authorities.”
