After suffering a major breach earlier this year, US Chinese restaurant chain PF Chang has said it is still investigating the incident, but it was the work of a “highly sophisticated gang”.
According to a security update from the chain, the incident is “being investigated by both the U.S. Secret Service and a team of third-party forensic experts” said CEO Rick Federico. Although the company did not reveal how the attack happened, how many restaurants were affected or who was responsible, some evidence shows that the breach began in September, reports Bank Info Security.
The CEO also said that improvements to the point of sale systems were almost complete, and in the near future it will complete the deployment of new hardware and begin the transition back to the standard card processing system.
