The marketing, access management and ticketing software company Gingerbread Shed recently began notifying an undisclosed number of customers that their names, user names, passwords, addresses, phone numbers, e-mail addresses and credit card information may have been accessed by hackers.

The breach, which was discovered in April of 2014, lasted from late November 2013 to mid-February 2014.

"Upon learning of the incident, we immediately began a forensic investigation to determine the extent of the criminal conduct," the company wrote in the notification letter [PDF]. "Further, we notified law enforcement officials and intend to work closely with them in the investigation. In addition, we have deployed additional security procedures to prevent future attacks."

While no credit protection services are being offered to those affected, all recipients of the notification letter are being advised to review their account statements and credit reports for fraudulent activity, and to consider placing fraud alerts or security freezes on their credit files.
