Sony’s XCP DRM is a collection of information regarding the DRM that Sony put on some CDs.
Sony really messed up their DRM implementation, letting spyware/adware/virus writers easily make their software un-detectable just by naming the files `$sys$myFile`. They’ve also included loads of GPL/LGPL software without complying to the requirements of releasing their sourcecode.
Some of the software used without permission is Lame, DeDRMS, Id3Lib, and mpglib.
When Sony was preassured to provide an uninstaller for the DRM root-kit, they managed to mess that up as well, leaving lots of stuff behind, including a function call to reboot the machine from an ActiveX control. The ActiveX uninstaller is even marked safe for scripting, meaning anyone can use the functions it exports.
The only plus side to the DRM implementation, is that it let cheaters in World of Warcraft cheat without letting the WoW anti-cheat software catch on.
