Online reputation management company recently sent a letter to its customers informing them that a cyber attack had exposed their personal information, though the company says no financial information or Social Security numbers were exposed.

According to a copy of the letter [PDF file] obtained by security blogger Brian Krebs, the information that was accessed included names, e-mail addresses, physical addresses, and in some cases, phone numbers, birthdates, occupational information, and encrypted passwords.

In response to the breach, the company says it has reset all user passwords "to prevent any possible unauthorized account access," and is offering a year of free credit monitoring to any customer who requests it within the next 30 days.

"Following the attack, our engineering and security team immediately conducted an exhaustive investigation, working closely with independent security experts to determine what information may have been accessed," the company stated in the letter. "We are also implementing additional security measures, beyond the high level of security that is already in place, to ensure your continued protection."

The company is asking customers with questions to call (866) 597-8199.
