Submission + - Vista Protected Processes DRM broken

W2k writes: "It's a well-known fact that Microsoft's Windows Vista operating system contains DRM features, intended to keep a user from manipulating protected digital content that passes through his system. One core part of the DRM in Vista is Protected Processes. In short, a protected process is given special privileges by the operating system to keep other processes from accessing its memory or injecting their own code into its execution path. For example, running a media player as a protected process would make it theoretically impossible for a hacker to read encryption keys for DRM:ed content from its memory space. Well, not any longer. ReactOS developer and well-known kernel hacker Alex Ionescu has published on his blog a tool that can protect or unprotect any process, no questions asked. Screenshots of the tool in action are provided, but no source code."
