US convenience store Wawa said on Thursday that it recently discovered malware that skimmed customers' payment card data at just about all of its 850 stores.

The infection began rolling out to the store's payment-processing system on March 4 and wasn't discovered until December 10, an advisory published on the company's website said. It took two more days for the malware to be fully contained. Most locations' point-of-sale systems were affected by April 22, 2019, although the advisory said some locations may not have been affected at all. The malware collected payment card numbers, expiration dates, and cardholder names from payment cards used at "potentially all Wawa in-store payment terminals and fuel dispensers." The advisory didn't say how many customers or cards were affected. The malware didn't access debit card PINs, credit card CVV2 numbers, or driver license data used to verify age-restricted purchases. Information processed by in-store ATMs was also not affected. The company has hired an outside forensics firm to investigate the infection.
Thursday's disclosure came after Visa issued two security alerts—one in November and another this month—warning of payment-card-skimming malware at North American gasoline pumps. Card readers at self-service fuel pumps are particularly vulnerable to skimming because they continue to read payment data from cards' magnetic stripes rather than card chips, which are much less susceptible to skimmers.

In late December 2019, fuel and convenience store chain Wawa Inc. said a nine-month-long breach of its payment card processing systems may have led to the theft of card data from customers who visited any of its 850 locations nationwide. Now, fraud experts say the first batch of card data stolen from Wawa customers is being sold at one of the underground’s most popular crime shops, which claims to have 30 million records to peddle from a new nationwide breach.
