Shellcode Executor/ Tester

This is a project meant for learning C++ and linux internals: a small tool to load, run and analyze raw shellcode in a controlled environment.

Goals

• Work with linux syscalls:
  • Memory management
  • Process control
• Build a practical tool for reverse engineering and binary exploitation.

Features

• Load and execute raw shellcode in a controlled environment.
• Test shellcode under different protection settings.
• Debug and analyze shellcode bahavior.
• Generate basic shellcode stubs for testing.

Implementation Plan

Phase 1

Basic shellcode loader

• Allocate executable memory and copy shellcode to allocated memory
• create function pointer and execute
• handle crashes

phase 2

Safe execution environment

• Fork based isolantion (execute in child process)
• Signal handling for segmentation faults
• Timeout mechanisms
• sandboxing:
  • seccomp filters
  • linux namespaces
• Memory protection toggling:
  • NX/DEP
  • Stack canary
  • RELRO
  • ASLR
  • PIE

Phase 3

Analysis Features

• Register state before/after execution
• Syscall tracing
• memory mapping display
• step-by-step execution
