SkillWeb & browsing

Guides your agent through solving Linux REPL and VM pwn challenges with full binary protections.

Available today. Use it from your connected AI after setup.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the KCTF Linux VM REPL Pwn skill

About this skill

Solve KCTF Linux ELF64 REPL and VM pwn chains with PIE, canary, NX, and Full RELRO. Use when the challenge is a prompt-driven interpreter or custom VM with a linked libc.

What this skill tells your AI

The instructions your AI receives, as published by manyuegong33/r0crawl_skills in skills/kctf-linux-vm-repl-pwn/SKILL.md and read by ahel’s review.

Workflow

  1. Record ELF type, mitigations, linked libc, and the prompt/command contract.
  2. Recover the dispatch path before attempting an exploit.
  3. Separate parser, interpreter, and state machine logic.
  4. Build a reproducible local run with the shipped libc.
  5. Verify the same input on the raw binary and the rebuilt exploit chain.

Use this pattern

  • ELF64 with PIE, canary, NX, Full RELRO
  • prompt-driven interpreter or VM
  • no direct numeric echo
  • libc-linked challenge binary
