CNN reports on an announcement by Visa and Mastercard (which does not appear on either of their respective websites) revealing that a hacker accessed the records of up to 2.2 million accounts via a contractor (Data Processors International) that processes their credit card transactions. According to CNN “the affected accounts make up about one-third of 1 percent of the 560 million MasterCard and Visa cards in the United States.” According to a Washington Post article, the exposed database contained 8 million records of customer data, including accounts from American Express as well.
