A few people wanted to see a kernel mode hook, here it is.

Just says when NtCreateFile is called and by what process and on what file/object

If NtCreateFile is already hooked, the program will not try to put it's hook in place as this causes a BSOD. McAfee and other AV's usually hook NTCF. It is impossible to hook over it as they will detect a virus and then just rehook.



The Extension 'rar' was deactivated by an board admin, therefore this Attachment is not displayed.

Oh I do like this. I've only ever used the KeServiceDescriptorTable to hook but patching looks pretty fun =].

I've never done the SSDT method lol. The only bad part about this patching is that if the function is already hooked, you will BSOd. Idk how it is in SSDT patching.
