Fast-food chain Wendy's said Thursday that customers' personal information was compromised in a series of cyber attacks that started last year. Wendy's, which has been investigating "unusual payment-card activity" since early this year, said that cardholder names, credit or debit card numbers and expiration dates are among data targeted in an attack on a point-of-sale system at some franchise-operated restaurants. The attack, discovered in May, had been underway since November. A separate attack, which lasted from October until it was disabled in March, compromised card numbers and other account information, but not names, said Wendy's spokesman Bob Bertini. The security breaches affected approximately 1,025 franchise-operated Wendy's locations in the U.S. Wendy's has more than 5,100 franchised restaurants in the U.S. and 582 company-operated restaurants. The company said there's no evidence that its company-owned restaurants were impacted by the attacks. Read more here
