Pentest CTF Binary

Purpose

Analyze binary files to understand their behavior, identify memory corruption vulnerabilities, and develop exploits (ROP, Heap, Format String).

Core Workflow

  1. Static Analysis: Inspect binary properties, protections (NX, PIE), and code structure using checksec and ghidra.
  2. Dynamic Analysis: Run the binary under a debugger (gdb) to observe behavior and register states.
  3. Vulnerability Identification: Locate crashes, buffer overflows, or format string bugs.
  4. Exploit Development: Construct payloads (shellcode, ROP chains) using pwntools.
  5. Remote Exploitation: Launch the exploit against the target server to retrieve the flag.
