Kernel Driver Fuzzing


JMC31337

Recommended Posts

Came across a cool little prog called ioctlbf...

Its used to try and BSOD the system via DeviceIOControl IRQ's which is how user talks to kernel via its sys drivers

 

For a quick example:

C:\ioctlbf_0.4\bin>ioctlbf -d IP -r 120040-120050    _                   _  _       ___   (_)              _  | || |     / __)    _  ___   ____ _| |_| || |__ _| |__   | |/ _ \ / ___|_   _) ||  _ (_   __)   | | |_| ( (___  | |_| || |_) )| |   |_|\___/ \____)  \__)\_)____/ |_|    v0.4[~] Open handle to the device \\.\IP ...

[0] 0x00120044        [1] 0x00120040Choice : 0

which begs my next question: If you have used this prog, does it take a LOOOOONNNNNGGGG time to fill up the DWORD buffers?

with 1024 DWORD buffers in this case some are filled others dont give that Error 259: No more data is available.

 

and if ya wanna play mean with other IRQ's

Another world, another time
In the age of wonder
Another world, another time
This land was green and good
Until the crystal cracked

Once more
They will replenish themselves
Cheat death again
The power of their source

The crystal

Oh my God this is the best

Uh, I want you to trip like me, I want you to have fun

...

sorry OPs, sometimes i get a lil carried away
