A simple elf injector

• Coded in C, it uses the segmentation padding injection techique, to inject shellcode in an code cave.
• It manipulates the original entry point (OEP), to point to the beginning of the shellcode, and then the shellcode restores the OEP and jump to it.
• It can infect static and dynamic linked Elf files.

Build:

• On your terminal, type: make
• To clean, type: make clean

Run:

• ./injector
• If you want to infectec static ones, use shellcode-static, otherwise use shellcode-dyn.
• After infecting, just run it.

Dynamic linked example:

• Infecting the ls program.
