Some Adidas Web sites remain offline today as a result of a "sophisticated" cyber attack discovered last week, the German sportswear company said.

                       "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," the company said in a statement on its news stream site. "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 has put in place additional security measures, the statement added, without going into details. The company also did not say what happened

                       As of this afternoon, adidas.com and miCoach.com were still inaccessible. "Due to technical difficulties our website is currently not available," the Adidas site said.

                       "We are working to restore the site as soon as possible. As the site was also scheduled for a number of exciting updates, we will use the current down time to make those changes," the miCoach.com site said. "This way the site will launch again with the latest and greatest developments already in place."

                       The message on the miCoach site said the company was aiming to have the site back up by the end of day on Tuesday.
