• Obtain all symbol information without source code and symbol information.
• Inject arbitrary code into the kernel. (Static patching the kernel image or Runtime dynamic loading).
• Kernel function inline hook and syscall table hook are provided.
• Additional SU for Android.

If you are using Android, APatch would be a better choice.

CONFIG_KALLSYMS=y

Supported Versions

Currently only supports arm64 architecture.

Linux 3.18 - 6.2 (theoretically)
