Crytek websites taken offline due to 'suspicious activity'

German developer and Crysis creator Crytek has taken several of its websites offline for security reasons due to "suspicious activity."

The security breach was discovered sometime yesterday, just before Crytek.com, Mycryengine.com, Crydev.net and MyCrysis.com were taken offline. All four sites now bear the following message:

"We recently became aware of suspicious activity relating to some of Crytek's websites and acted quickly to take those websites offline for security reasons. We thank you for your patience, and expect to have these sites fully operational soon."

Other sites, such as Crysis.com, are unaffected. According to Blue's News, users on the impacted sites were sent an email suggesting a password change when the sites regain function.

No other details were given about the suspicious activity, nor an estimated time as to when those sites would be back up. We've contacted Crytek for comment and will update accordingly.
