This is a little something I've been working on in my free time, It's a bootkit that works on XP SP1+ written using FASM. Right now I have no intentions of making it work on other operating systems as I don't have much free time, but I'm sure someone will find it interesting.

It's a bootkit that works on XP SP1+

finally someone made a bootkit specially for windows xp x86... it is so popular on the market these days, especially after microsoft stoped supporting it... :D

but anyway, feels good to see that you are learning something at least... ;) go and make a video on your pdf-presentation...

Just re-read the PDF, if you're really stuck I'll make a step-by-step video just for you. :P

Very interesting... this kind of malware it's very powerfull, the only problems is this kind of tech it's already dead,because nowadays UEFI (Secure Boot) do not let you to install unsigned boot code :(


My brain is going to explode when i close my eyes i see OPCODE :|

I believe the boot components were changed between XP SP0 and XP SP1, I can easily make the bootkit work on XP SP0, but I don't have a bochs install running that OS (XP takes about 2 hours to install in bochs). If i get more time I'll add XP SP0 and XP 64-bit functionality (maybe some vista and windows 7). As far as I'm aware XP SP0 and windows 2000 also share a bootloader so I can also add support for that easily.

There are ways to bypass UEFI secure boot by exploiting the UEFI firmware, but releasing code to do that would be asking to go to jail.
