Katana is a Python CLI tool by John Hammond that automates common low-hanging-fruit checks for CTF challenges, paired with ctf-katana, a curated living document of tools and commands for CTF categories like enumeration, forensics, crypto, web, and binary exploitation. Together they serve as both an automated helper and a reference guide for capture-the-flag players.

Use cases

  • automate common checks on a CTF challenge file
  • find tools for solving SMB enumeration challenges
  • look up commands for steganography or forensics challenges
  • get started with capture the flag competitions
  • quickly triage unknown CTF binaries or files
  • find reverse shell and post-exploitation commands
  • reference commands for HackTheBox or similar platforms

When to choose

  • you play CTFs and want a curated cheat sheet of tools and commands
  • you want to automate routine low-hanging-fruit checks on challenge files
  • you are a beginner looking for guidance across many CTF categories

When to avoid

  • you need a professional penetration testing suite for real engagements
  • you need a maintained tool with active releases and a clear license
  • you want a GUI or polished workflow rather than a script and reference list
