Ubisoft’s recently announced that a new DRM scheme for PC games that many claimed would be uncrackable. It appears that this DRM has been busted in 24 hours.
The DRM mechanism in question, rolled out initially in Silent Hunter 5 and Assassin’s Creed 2, took a new approach in that it relied on having a constant internet connection in order that the game files could be checked continuously for modifications or tampering. If modified files were detected or the internet connection dropped (or for that matter if Ubisoft’s servers went down), the game would shut down.
