Papa Shango is a Linux process injection tool that utilizes the ptrace() system call to inject shellcode into running processes. The tool enables users to write payloads in assembly language and handles NULL bytes without restrictions. The injection process involves combining the Papa Shango binary with shellcode to create an executable payload. Users can then execute this payload against a target process by specifying the process ID (PID) as a command-line argument. The tool operates at the system level by leveraging ptrace(), a debugging interface that allows one process to control and modify another process's execution. This capability makes it suitable for post-exploitation activities and process manipulation scenarios in penetration testing environments.
