Data of one million credit cards stolen during a Target site violation last month are marketed on the black market according to the black market hit, according to the New York Times.
The security company Easy Solutions noticed an increase in stolen high-value cards at known "shops" that is 10 to 20 times higher than the numbers they knew. "The stolen ones cards it's from almost every bank,” the New York Times reports.
Security researcher Brian Krebs, who first announced Target's hack, reported on Friday that hackers are selling 1 million cards from 20 up to over 100 dollars on the card.
Those who buy the cards, make a copy and use them for purchases from stores. Of course, if they know the owner's PIN, they can easily withdraw cash. Target CEO Gregg Steinhafel said in a message to their customers that "there is no indication that PIN numbers have been compromised."
The company said it would complete the update and the 40 million customers this weekend. These customers made purchases at Target stores from 27 November to December 15.
