Inject shared object to running process in linux

Linux so injector

Requirement

1. only support x86 64bit architecture.

This project aims to inject a Shared object into a process running on Linux.

• Supports multi-thread safe.
• Sacrificed stability for fastest injection.

Test in Ubuntu 18.04 64bit.

Example

$ make
$ ./sample-target
pid: 72935
addr: 0x601058
pid: 72936
addr: 0x60105c

# open another terminal to run the injector
$ ./injector sample-library.so 72935
injector: size of code to inject 207
injector: Path of Shared object to be injected : /home/m/git/linux_so_injector/sample-library.so
injector: RIP Register : 400f32

then you can see the messsage that shared object has printed.

$ ./sample-target
pid: 72935
addr: 0x601058
pid: 72936
addr: 0x60105c
