As you probably know by know, MasterCard reported a breach in its security on Friday, and credit card issuers still don't know for sure which customer accounts were affected. Over 40 million accounts were exposed in the breach. Data was stolen from about 200,000 accounts. Card issuers are waiting to hear from MasterCard about which accounts have been jeopardized.
"Consumers should wait for notice from the bank," said the U.S. Public Interest Research Group's consumer program director Edmund Mierzwinski. "In the interim, if consumers have the ability to check credit and checking accounts online they should do that and if not, they should open and review their statements very carefully the next couple of months."
No one at CardSystems is commenting on the security breach, but an FBI investigation is in progress. The data that was jeopardized included names, account numbers and verification codes.
