The K55 payload injection tool is used for injecting x86_64 shellcode payloads into running processes. The utility was developed using modern C++11 techniques as well as some traditional C linux functions like ptrace(). The shellcode spawned in the target process is 27 bytes and it executes /bin/sh (spawns a bash shell) within the target’s address space. In the future, I will allow users to input there own shellcode via command line arguments.
