elf-pwn-triage

elf-pwn-triage is a skill for Claude Code, Codex from liuxinye23/CyberStrikeAI. It costs 39 tokens per session (586 once invoked), scanned A, original, Apache-2.0.

A first-pass guide for analysing ELF programs, the executable format commonly used on Linux, in capture-the-flag exploitation challenges.

In plain words
What is it for?
Use it to inspect stack, heap, format-string, and logic bugs; input lengths and indexes; address leaks; local versus remote differences; and tools such as GDB and pwntools.
Why use it?
It quickly identifies the program’s architecture, defensive protections, controllable inputs, information leaks, and likely type of memory flaw.

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 A, and why

elf-pwn-triage scanned grade A with 0 findings 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 11d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ELF Pwn 题首轮 triage

何时使用

当题目提供 ELF、菜单程序、远程 nc 端口、明显崩溃点或交互式本地/远程程序时使用。

快速流程

  1. 确认架构、位数、动态/静态链接、是否有符号与 libc 依赖。
  2. 识别保护:栈保护、PIE、NX、RELRO、FORTIFY、沙箱或 seccomp 痕迹。
  3. 梳理输入面:菜单、长度字段、格式化输出、文件读写、索引、指针操作。
  4. 先判断更接近栈、堆、格式串还是逻辑型原语。

重点检查

可控面

  • 哪个输入真正决定长度、索引、地址、格式串或生命周期。
  • 程序是否在多个阶段复用同一缓冲区或对象。

信息泄露

  • 是否存在地址、libc、栈、堆、指针、错误信息等泄露源。
  • 很多题先要做的是“拿到稳定泄露”,不是立刻构造最终利用链。

远程约束

  • 远程与本地的 libc、超时、交互方式、菜单节奏是否一致。
  • 如果远程只允许少数轮交互,优先优化最短利用路径。

建议工具

  • strings
  • gdb
  • pwntools
  • ropper
  • one-gadget

输出要求

  • 架构与保护概况
  • 主要输入原语
  • 泄露面与潜在利用方向
  • 本地/远程差异

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.
