A massive data breach has hit Target (TGT) debit and credit cards that has compromised the data of 40 million customers.
The retailer said that it has identified and resolved the problem and there have been no cases of fraud reported since the data breach was discovered. However, hackers with access to these cards are selling their data as fast as they can since some cards are set to expire soon. Meanwhile, Target is conducting an investigation along with a third-party forensics crew to learn more details about the data breach and the hackers.
“My best guess is [Target] got hit by hackers who got into their network, and were able to push malicious software out to the point of sale systems,” says security blogger Brian Krebs. “We probably won’t know for certain for weeks or months.”
Following this data breach, it’s only a matter of time before people buy credit and debit card data in underground websites. Krebs says that hackers are selling account data for $44 apiece.
