More than 130 restaurants at the Cicis pizza chain were the recent target of hackers. The hackers struck by secretly installing malware into the restaurants point-of-sale systems. Other companies, including Wendy’s and Target, have been attacked in the same way in order to steal payment card data. The company is warning customers to be on alert for fraudulent credit card charges, and has already alerted payment card companies about the breach. The pizza chain has eliminated the malware, it said.”]
