HowToKernel

This Repository aims at giving a basic idea about Kernel Exploitation.

Setup the environment

• Clone the repository to your system git clone https://github.com/R3x/How2Kernel ~/How2Kernel.
• Go to the folder containing the setup cd ~/How2kernel
• run setup.sh to setup the Lab and testing environment
• In case you want to run the modules in your own system ./setup.sh -local
• To build a virtual environment with QEMU ./setup.sh -virt -<architecture>.
• Start Hacking the kernel !!!

• Make sure there are no spaces in the path to the directory that you have cloned. This will cause errors while building.
• Architectures supported currently -arm for Aarch 64 architecture and -x86 for amd64 architecture.
