Major Data Breach Being Researched Posted by AVCU on 12:07 PM

Brian Krebs, a former Washington Post reporter who now publishes a blog focused on online security issues (Krebson Security), posted in his blog that VISA and MasterCard are alerting credit card issuers about a recent major breach at a U.S.-based processor. Sources are calling the breach “massive,” and say it may involve more than 10 million compromised card numbers.


Reportedly, the breached credit card processor was compromised between 1/21 and 2/25, and full Track 1 and Track 2 data was taken – meaning the information could be used to counterfeit new cards. Two major affected financial institutions say their affected transactions have New York City area parking garages in common. Earlier this week, credit union processor PSCU alerted 482 credit unions of 56,455 compromised cards, with fraudulent activity on 876 accounts of those.
