Network Solutions is investigating a breach on its servers that may have led to the theft of credit card data of 573,928 people who made purchases on Web sites hosted by the company.

Networks Solutions notified 4,343 of its nearly 10,000 e-commerce merchant customers on Friday about the breach. It affects 573,928 cardholders whose name, address, and credit card number were exposed between March 12 and June 8, said Susan Wade, a spokeswoman for Network Solutions.

Mysterious code was discovered in early June on servers hosting e-commerce customer sites during routine maintenance, she said. The company called in a third-party forensics team to help with the investigation, and the team was able to crack some of the code on July 13, determining that it could be related to credit card data, she added.

Credit card transactions were intentionally diverted by an unknown source from certain Network Solutions servers to servers outside, Network Solutions wrote in an e-mail to merchant customers.

“So we notified law enforcement and began the process of notifying our customers,” Wade said. “At this point, we don’t have a reason to believe that (the data) has been used, but we are working with the credit card companies,” nonetheless.

Network Solutions also is paying to have credit-monitoring specialist TransUnion help the merchants notify their customers according to data breach notification laws in effect in certain states. Affected consumers will get 12 months of free credit-monitoring services.

It’s unknown how the malicious code got onto the system and where it came from, Wade said. (Read more at: cnet)
