Forever 21 immediately began an investigation of its payment card systems and engaged a leading security and forensics firm to assist.” announced FOREVER 21.“Because of the encryption and tokenization solutions that FOREVER 21 implemented in 2015, it appears that only certain point of sale devices in some FOREVER 21 stores were affected when the encryption on those devices was not in operation. The company’s investigation is focused on card transactions in FOREVER 21 stores from March 2017 – October 2017.”
