Hibernation File Attack
The idea behind the hibernation file attack is to inject code into the hibernation file when the system is hibernated. The unsigned code will be written into hibernation file directly before Windows starts - and when Windows processes a system resume, the modified kernel will be loaded. The injection is done via an own modified Master Boot Record. The MBR is executed before winresume.exe and is able to modify the hibernation file (hiberfil.sys) via its own file system drivers (FAT and NTFS). The MBR will be written to disk by a normal application using raw sector access.

The main source code, the Master Boot Record and all its modules, is not available for download now. It will be made available with my "Stoned" project. If you have any interest in it feel free to contact me. The reason for not publishing it is that the Source Code can load ANY MALICIOUS UNSIGNED CODE into kernel, even in Vista, and Windows 7.
If you have any question regarding the Hibernation File Attack, please contact me using the secured contact form.
