A thriving online bazaar selling stolen payment card data has been hacked in a heist that leaked the records for more than 26 million cards, KrebsOnSecurity reported on Tuesday. The 26 million figure isn’t significant only to the legitimate consumers and businesses who own the stolen cards or the financial institutions that issued them. Fortunately for the card owners, the database is now in the hands of affected financial institutions, who can invalidate and replace the cards. The number, therefore, is perhaps a bigger deal because it represents a significant fraction of the world’s stolen-card inventory. Krebs said that Gemini Advisory, a company that monitors dozens of underground markets trafficking stolen card data, currently tracks a total of 87 million credit and debit card records. The haul of 26 million cards means that about a third of that supply has been taken out of circulation in a single swipe.
