Forever 21 announced on Tuesday that customers who shopped in certain stores this year may have had their credit-card information stolen.
Customers who shopped in store from March 2017 through October 2017 may be affected.
A third-party monitor alerted the retailer to the fact that in some instances, an encryption used to hide customer credit-card data was not functioning properly.
The number of people potentially affected was not yet available, but Forever 21 said in a press release that its investigation is ongoing. The company did not immediately return Business Insider's request for comment.
