After sending out a warning last month, Jason's Deli now confirms criminals gained access to its point-of-sales terminals inside restaurants, putting approximately 2 million customer's credit card information at risk.

The restaurant company was notified in December that a large quantity of payment card information had appeared for sale on the "dark web."

Jason's Deli says they immediately went into action, including a threat response team, forensic experts and law enforcement.

Investigators now say the criminals deployed RAM-scraping malware on the point-of-sale terminals at various corporate-owned Jason's Deli restaurants starting June 8, 2017.

Jason's Deli says the security breach has been contained, and has been disabled in all of the locations where it was discovered.

As many as two million credit card numbers may have been impacted.

Jason's Deli released a list of potentially affected stores, 71 of which are located in Texas.
