Heartland Payment Systems has reported it suffered another data breach last month.
In a letter to the California Attorney General, the Princeton, N.J., payments processor disclosed a May 8 incident in its Santa Ana, Calif., office that may have compromised customers' personal information, including social security numbers and bank account information.
Heartland did not indicate the size or scope of the breach.
In 2008, Heartland suffered what is now considered one of the largest ever criminal data breaches, having exposed data of up to 100 million credit and debit cards issued by more than 650 financial services companies. The cost for Heartland was more than $32 million.
According to the letter, in the May 8 breach, password protected company computers were stolen, but Heartland claims it sees no evidence to suggest the data stored on them were or will be used.
The company said it is involving regulatory and law enforcement agencies to help it move forward. It's working with risk mitigation services company Kroll to offer customers identity theft protection for a year at no cost.
