CTF•二进制利用

CTF•二进制利用 is a skill for Claude Code from asdfgh1445/ctf-super-hub. It costs 65 tokens per session (4,727 once invoked), scanned C, original, no licence file.

A guide for solving binary-exploitation challenges in Capture the Flag (CTF) competitions, where players find ways to control a program’s behavior. It covers issues such as buffer overflows, format-string bugs, heap misuse, and sandbox escapes.

In plain words
What is it for?
Use it for CTF tasks involving compiled programs, memory corruption, ROP, ret2libc, shellcode, kernel bugs, or restricted execution environments.
Why use it?
It helps turn difficult low-level exploitation work into a focused solving process instead of requiring you to choose techniques from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

CTF•二进制利用 scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
