As Aunty reported last week, the personal data of 40 million consumers was compromised when CardSystems Solutions had their computer system hacked. CardSystems provides back-end processing for MasterCard and Visa transactions.

Now a lawsuit has been filed in San Francisco against CardSystems, requesting that they be required to notify all of the consumers whose data was compromised during the breach, to give “special notice” to those consumers whose personal information has been confirmed to have been stolen, and offering credit-monitoring services to all 40 million whose information was compromised.

To date, those involved on the credit side have failed to notify consumers whose information has been put at risk unless the information has been confirmed stolen and their credit account actually abused.

Said Ira Rothken, the California attorney who filed the lawsuit on behalf of both consumers and merchants involved, “Millions of consumers have had their private credit card data compromised and are just going to have to wait and see to what extent the data will be used fraudulently or exploited it in other ways. This is causing consumers enormous apprehension and concern.”
