Food delivery service recently began notifying an undisclosed number of customers that their personal and payment card information may have been exposed as a result of a data breach.

"Our online ordering software provider, BigTree Solutions, recently informed us that they identified unauthorized modifications in their software that could potentially allow new payment credit card information entered between October 14, 2013 and January 13, 2014 to have been obtained by an unauthorized user," co-founders Sherry Nep and Brian Whorley wrote in the notification letter [PDF]. "To the best of our knowledge at this time, if you entered your payment card before or after this date range, the information was not compromised."

According to the notification letter, BigTree Solutions has corrected the "unauthorized modifications," and has put new processes in place to prevent a similar breach occurring in the future. The company is also working with a security firm to investigate the incident and to implement additional security measures.

While no credit protection services are being offered to those affected, the notification letter advises all recipients to consider placing fraud alerts on their credit reports. notes that the same breach at BigTree Solutions also exposed the personal information of up to 900 customers of restaurant delivery service The Bike Waiter.
