- Adidas said "limited" information was compromised including customers email and physical addresses, usernames and encrypted passwords.
- Insider sources said a "few millions" of customers were impacted in the breach.
Sportswear giant Adidas said it suffered a data breach that potentially impacted millions of customers who used its US website. The company said it became aware of the breach on Tuesday when it learned that an unauthorized party claimed to have acquired some of its customer data.
The "limited" compromised data include customers' email addresses, physical addresses, usernames and encrypted passwords, as per Adidas' preliminary investigation.
"We are alerting certain consumers who purchased on adidas.com/US about a potential data security incident. At this time this is a few million consumers," the company said. "Adidas has no reason to believe that any credit card or fitness information of those consumers was impacted."
The athletic apparel firm said it is currently investigating the breach with law enforcement and security firms. It is still unclear when and how the breach occurred. Adidas has not specified exactly how many people were affected by the breach.
However, several media outlets cited inside sources who said that a "few millions" of Adidas customers were likely impacted.
Adidas' disclosure comes as the latest in a string of data breaches that came to light this week.
Ticket-selling giant Ticketmaster announced a breach that affected nearly 5% of its global user base, but not its North American customers. The breach occurred after hackers managed to exploit a customer service widget on its payments page that was handled by third-party firm, Inbenta.
Marketing firm Exactis reportedly exposed a massive database containing nearly 340 million records of Americans and businesses on a publicly accessible server. The database contained detailed personal information such as phone numbers, home addresses, and even the number of children they have, their age and gender.
Paris-based hotel booking service Fastbooking also said hackers exploited a vulnerability in a web application hosted on its server to steal customer data. The breach impacted hundreds of hotels from around the world and their guests.
