“Brian Krebs, the venerable security journalist who first reported the insane Target Holiday Security Breach that exposed up to 40 million credit cards, has located one of the black market sites selling the card information and says they are going for $20 to $100 each. They can be bought using, of course, Bitcoin, as well as other irreversible and semi-anonymous ways of sending money including Litecoin, WebMoney, PerfectMoney, and traditional wire transfers. Krebs went shopping on the black market to help a small New England community bank which has 120,000 cards in the wallets of its customers and wanted to know how many of them are for sale for fraudsters this holiday season.”
