Singapore-based cybersecurity company Group-IB has found a data dump of more than 1.3 million credit and debit cards, mostly India records, on a dark web site called Joker’s Stash.
More than 98% of the card records belong to Indian banks, while nearly 1% come from Colombian banks.
Group-IB said over 18% of the dumps in the database are associated to a single Indian bank.
Every single dump in the set is valued at $100, valuing the entire database at over $130m.
The dump holds Track 1 and Track 2 records, which Group-IB said can be used to produce cloned cards for further cashing out.
Group-IB CEO and founder Ilya Sachkov said this is indeed the biggest card database encapsulated in a single file ever uploaded on underground markets at once.

Sachkov said: “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.”
Earlier this year, the Singapore firm uncovered Android Trojan, dubbed Gustuff, capable of targeting global banking apps, cryptocurrency and marketplace applications.
Gustuff is expected to potentially target users of over 100 banking apps, including 27 in the US, 16 in Poland, 10 in Australia, 9 in Germany, and 8 in India and users of 32 cryptocurrency apps.
