Wendy’s Co. has found malware in the systems at some of its restaurants.
The Dublin-based chain in late January said it was investigating “unusual activity” related to credit cards used at some of its restaurants.
Tuesday it provided a brief update on the issue.
“Out of the locations investigated to date, some have been found by the cybersecurity experts to have malware on their systems,” the company said in a statement. “The investigation is ongoing and the company is continuing to work closely with cybersecurity experts and law enforcement officials.”
Wendy’s (NASDAQ:WEN) said its contacts in the payment industry notified the company of fraudulent charges that were occurring at other businesses after payment cards were legitimately used at some Wendy’s restaurants.
The company still has not said how many restaurants have been affected.
“As always, in line with prudent personal financial management, we encourage our customers to be diligent in watching for unauthorized charges on their payment cards,” Wendy’s said in its January statement. “Generally, individuals that report unauthorized charges in a timely manner, to the bank that issued their card, are not responsible for those charges.”
