Bike brand Canyon was hit by a “massive cyber attack” just before the new year, the company has announced. The attack was perpetrated by a group of criminal hackers that specialize in targeting companies.

The hack will result in mild delays in customer contact and delivery in the next few days. Canyon did not release any additional information about the hacking group but did note that authorities have been notified. The intrusion has been stopped, according to Canyon.

“The attack shows massive criminal intent,” said Canyon CEO Roman Arnold. “Due to the encryption of our IT infrastructure, work and business processes were temporarily massively affected.”

Canyon is the industry’s largest direct-to-consumer bike brand and relies on its online systems to take individual customer’s orders, as well as provide support. Though the perpetrators succeeded in gaining access to Canyon’s IT systems, Canyon’s website was not affected, and orders via the web shop were not affected. The company’s Koblenz headquarters was directly affected, as well as most of its international operations. Its US operations were not affected, as it operates using its own IT system.

“We are making every effort to keep the impact on our customers and fans as low as possible and to get back to normal operations as quickly as possible,” Arnold said. “We regret this incident very much and apologize that Canyon is currently not able to offer its usual standard of service.”
