Security Breach Exposes 40M Credit Cards

The Good Reverend writes "MasterCard International announced today that a security breach at CardSystems Solutions, a third party processor of payment card data, potentially exposed more than 40 million cards. Mastercard is aware of the specific card numbers affected, and is giving its member financial institutions the numbers that may have been compromised. Unlike many of the past high profile cases this one involves a hacker rather than lost packages. CNN Money, the New York Times, Reuters, MSNBC, ZDNet, C|Net, and the Washington Post are also covering the story."
