Hackers sink their teeth into Arby’s credit card data

According to a report from cybersecurity expert Brian Krebs, the company discovered the breach in mid-January and that it impacted roughly 1,000 corporate restaurant locations but only one of its franchise restaurants.

Krebs noted that the first mention of the breach came from a Credit Union Service Organization (CUSO) called PSCU, which sent out a non-public alert to the 800 credit union member banks it serves advising that it had received a list of compromised card numbers from Mastercard and Visa.

Though the retailer wasn’t named at the time, PSCU said more than 355,000 credit and debit cards issued by PCSU-associated banks were compromised in the data breach.
