The Adidas Group, a premier German sportswear and equipment maker, closed down all its websites last week after what it called a “sophisticated and criminal cyber attack.” The company doesn’t believe that any consumer data was impacted, but the company plans to continue its investigation.

Currently, a statement that replaced the www.adidas.com home page reads, “On November 3, 2011, the Adidas Group found out that it was the target of a sophisticated, criminal cyber-attack. Our preliminary investigation has found no evidence that any consumer data is impacted. But, while we continue our thorough forensic review, we have taken down affected sites, including adidas.com, reebok.com, miCoach.com, adidas-group.com and various local eCommerce shops, in order to protect visitors to our sites.”

The company added that it has put additional security measures into place, but didn’t go into any details about what those measures were. The company also didn’t say anything about what happened.

Adidas.com and miCoach were still inaccessible as of Tuesday November 8.

The miCoach site said, “To miCoach Friends. Unfortunately our site is not available at the moment. A detailed statement explaining the reason is available from the Adidas Group.”

The miCoach site also said, “As the site was also scheduled for a number of exciting updates, we will use the current down time to make those changes.”

The message on the miCoach site also mentioned the company hoped to have the site back up by the end of day on Tuesday.

Despite the problems with other Adidas websites, several are still online, and don’t appear to be affected.

Adidas first became aware of the attack on November 3. At the time, the company its group website, www.adidas-group.com with a notice, but has since restored that site.

The other websites (adidas.com, reebok.com and micoach.com) occasionally displayed various error messages or redirected users to different sites, indicating that changes are still being made on Adidas’ web servers.
