Nothing new, just had laying on HD and RG was interested, havent seen one in fasm tho...
Next step to do would be adding hooking of USEFULL api's Twisted Evil

Have fun...

Description:	everyone who has any doubt on binaries I provided, I suggest compiling .sys, and getting(or using other tool to load driver) KmdManager that comes along masm-ddk by Four-F, wasm.ru has the package I think.	Download

I will research this further. You also have very clear code, not crazy about the hungarian notation though Smile

.

Maybe someone should convert the DDK to fasm.

Thanks.

I think i found a bug in code:

Code:

        mov     dword [eax+DRIVER_OBJECT.MajorFunction+IRP_MJ_CREATE], DispatchCreateClose              ;driverobject+038h
        mov     dword [eax+DRIVER_OBJECT.MajorFunction+IRP_MJ_CLOSE], DispatchCreateClose               ;driverobject+040h
        mov     dword [eax+DRIVER_OBJECT.MajorFunction+IRP_MJ_DEVICE_CONTROL], DispatchCreateClose      ;driverobject+070h

IRP_MJ_CREATE, IRP_MJ_CLOSE, IRP_MJ_DEVICE_CONTROL are just indexes in array of procs tus they should be multiplied by 4 to get addresses.
The correct code should be imo like this

Code:

        mov     dword [eax+DRIVER_OBJECT.MajorFunction+IRP_MJ_CREATE*4], DispatchCreateClose              ;driverobject+038h
        mov     dword [eax+DRIVER_OBJECT.MajorFunction+IRP_MJ_CLOSE*4], DispatchCreateClose               ;driverobject+040h
