Fast food chain Wendy's announced in February that is was looking into a possible security breach. The franchise followed up in May confirming it found malware on its point-of-sale systems that was being used to nab credit card info. Stolen details were said to include including credit or debit card number, expiration date, cardholder verification value, and service code from less than 300 locations. Last month, the company provided and update that the investigation revealed the breach could be much worse due to a second cyberattack. Wendy's gave another update on the situation this week, disclosing that over 1,000 locations had systems where the malware was installed.
