Disable PatchGuard & Driver Signing

Hello,

This patch is for Windows 7 X64 RTM & Windows 7 SP1. It directly modifies ntoskrnl.exe & winload.exe to remove Microsoft's "PatchGuard" and requirement of driver signing.

This is accomplished by patching 6 bytes inside ntoskrnl.exe and four bytes inside of winload.exe ... it is file patch version of my existing bootkit

I originally made this for myself... wanting to again be able to hook inside of ntoskrnl like with X86 Windows.

Hope that someone find this useful,

-Fyyre

p.s. attachment updated for SP1 -- new attachment added on 8 March, 2011

Seems like I got not enough permission to access the file, probably due to my different user group. Just some minor setting in the board panel I guess.

Thanks anyway, I guess I already read about it on your page.

I can't seem to download this attachment either. Is there a certain amount of posts I'm supposed to have before I can download attachments?

Promotion is a manual process and does not get done on a set schedule. However, your post count qualifies you for promotion to "Trial Member", and they have upload and download privileges.

Please give it a try again.

Hi Ahmadmansoor,

A tutorial to disable the PatchGuard and Driver Signing? Or did you have something else in mind?
