Hackers stole customers’s credit and debit card information from nine South Florida Wendy’s restaurants in a security breach that affected more than 1,000 of the chain’s restaurants, the hamburger chain confirmed Thursday.
Beginning in last fall, hackers were able to obtain card numbers, names, expiration dates and codes on the card, at 1,025 of Wendy’s U.S. restaurants — far more than originally thought. Some customers' cards were used to make fraudulent purchases at other stores.
Wendy's Co. urged customers to check their accounts for any fraudulent purchases.
The Dublin, Ohio, company first announced it was investigating a possible hack in January. In May, it said malware was found in fewer than 300 restaurants. About a month later, it said two types of malware were found and the number of restaurants affected was "considerably higher."
There are more than 5,700 Wendy's restaurants in the U.S.
Wendy's released a list of affected restaurants on its website Thursday and said it would offer free one-year credit monitoring to people who paid with a card at any of those locations.
Out of the Florida cities listed, Miami-Dade County had the most restaurants affected. Two restaurants in Monroe County, in Marathon, were also affected.
Here are the South Florida cities impacted:
