Adidas has published a customer warning that its U.S. customers could be at risk from a security incident it discovered on June 26, 2018. In the warning, Adidas says that it will reach out to certain customers who purchased goods through its website with more details about the incident. It has been reported that the incident could have affected millions of Adidas customers.

Adidas says it is in the process of undergoing a thorough forensic review, but that the initial analysis indicates that the customer information compromised includes customers’ usernames, encrypted passwords and contact information. Even though it appears that usernames and encrypted passwords were involved, Adidas stated that it is not aware that any credit card or fitness information was compromised.

Nonetheless, those who have purchased items through the Adidas website may wish to consider changing their password for the Adidas platform.
