Reverse Engineering Simple Windows Driver

In this video I will demonstrate how you can reverse engineer a simple "Hello, World" driver on Windows 10.
Dependencies:
- Cutter: winget install Rizin.Cutter
- Windows Debugger (windbg): winget install Microsoft.WinDbg
Docs:
- DbgPrint: learn.microsoft.com/en-us/win...
- COM Port Kernel Debugging: learn.microsoft.com/en-us/win...

I didn't vote for this video, but I'm glad it won! As someone who develops hardware that needs to interact with Windows drivers, the kernel debugger seems very useful for figuring out what the driver's "quirks" (bugs) are to workaround them.

Just tested Cutter with simple win32 program although I don't understand much of the disassembly it generated. Thank you for the amazing video. Keep it up 👍👍

Interesting video!

Sir, The uttmost respect to your work you have made malware reverse engg onboarding very easy with this video this is how MicroSoft must make their docs not some tedious legthy cryptic docs. In the next Video please try to run windows on raspberry pi so that we can learn the same way to reverse windows arm64 drivers

[@homework8969]

It would be cool if you could do this with some off the shelf drivers, although Im pretty sure that youtube wouldn’t like that.

Bro, how to read the contents of a dll file, and change it in a windows machine? And thank you for your prominent efforts to improve your channel to give us valueable knowledge about low level stuff

[@nirlichtman]

You can use cutter for that :)

Can you create a video for installing the visual studio build tools on Ubuntu 22.04 pls?

[@alargeboat]

hey Nir, as a possible video idea, could you maybe make a video on making a simple TUI app using ncurses/curses in C?

[@nirlichtman]

I have a video on making snake with curses, but its a good idea, ill consider also making a vid dedicated to making a simple tui visual editor or something like that using curses

[@alargeboat]

Please help me, how to simulate keyboard with kernel mode driver. Thank you.

[@nirlichtman]

You want to send keystrokes? Why not do that from user mode using for example SendInput? learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-sendinput
