Proof-of-concept ELF binary injection into a running process.
Make sure you have gcc, make and cmake installed. Then run make.
sudo /<path-to-build>/inject <pid> <path-to-binary>- pid: Process ID of the process to inject into.
- path-to-binary: Binary to inject into the process.
The binary to be injected must relocatable. You can figure this out by running:
readelf -h /bin/vim | grep "Type:"If the type is DYN then it is relocatable. Pretty much all binaries are relocatable now due to ASLR, so this shouldn't be an issue.
The process that is being injected into will no longer execute the code it was originally running. If this is a critical process, your system will suffer the consequences.
