(Bloomberg) -- Wendy’s Co., which reported a hacker attack earlier this year at its franchisee-owned restaurants, said that the breach was significantly bigger than it initially thought.
The company discovered malicious software aimed at getting customers’ payment-card information from point-of-sale systems, according to a statement on Thursday. After saying on May 11 that the malware was found at fewer than 300 North American restaurants, Wendy’s now expects the number of affected locations to be “considerably higher.”
The fast-food chain said it has disabled the malware, but “reports indicate that payment cards used legitimately at Wendy’s may have been used fraudulently elsewhere.” There’s no sign that company-owned restaurants were affected.
Retailers and restaurant companies, including Target Corp. and Home Depot Inc., have suffered a spate of hacker attacks in recent years. U.S. chains began using European-style chip cards last year in a bid to tamp down fraud.
