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.
Although details of the breach are still unclear, Forever 21 is focusing in on card transactions that occurred between March and October this year.
Teen and millennial fashion retailer Forever 21 issued a statement Tuesday warning customers of a potential data breach that may have compromised credit card information.
The company has a store in Tulsa's Woodland Hills Mall. The Los Angeles-based company did not provide any details regarding when or how the point-of-sale (PoS) breach took place, or what payment card details may have been compromised. The brand says complete findings are not yet available. "Forever 21 expects to provide an additional notice as it gets further clarity on the specific stores and time frames that may have been involved".

The two countries would also "exchange opinions on matters of mutual concern" during the visit, Geng added. The last time China's special envoy for North Korea visited the country was in February a year ago .
"We regret that this incident occurred and apologize for any inconvenience", Forever 21 said.
Right now Forever 21 is not releasing the locations of the stores being looked at for the possible security breach.
It advises customers to keep a close eye on their credit- and debit-card statements and notify their bank or card issuer if any unauthorized charges pop up on them.
