wasm-reverse-triage

wasm-reverse-triage is a skill for Claude Code, Codex from liuxinye23/CyberStrikeAI. It costs 35 tokens per session (520 once invoked), scanned A, original, Apache-2.0.

A first-pass workflow for CTF challenges involving WebAssembly, JavaScript, or browser-side checks. WebAssembly is a compact format that lets code run in a web browser, often alongside JavaScript.

In plain words
What is it for?
Use it to inspect WASM files, JavaScript bundles, source maps, configuration files, browser storage, routes, constants, and the order of user interactions.
Why use it?
It helps determine whether the important validation happens in the browser or on the server and identifies the resources that control the challenge.

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

wasm-reverse-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 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.

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

WASM 与前端逆向题首轮分流

何时使用

当题目包含 .wasm、前端大包、浏览器端校验、客户端 flag 逻辑、JS 混淆或前端解谜流程时使用。

快速流程

  1. 先确认校验在浏览器端还是后端。
  2. 找出关键资源:JS bundle、WASM、Source Map、配置 JSON、动态加载脚本。
  3. 识别题目是“还原算法”“提取常量/密钥”还是“理解交互顺序”。

重点检查

入口与调用关系

  • WASM 从哪里加载、由谁调用、输入输出如何传递。
  • JS 与 WASM 是否共同参与校验,还是其中一个只是包装层。

常量与提示

  • 先找字符串、错误文案、隐藏路径、调试标志、字典表。
  • 对纯前端题,不要忽略浏览器存储、请求参数、路由片段和资源命名。

状态机与交互

  • 某些题目关键不在算法,而在触发顺序、事件链、路由状态、时间检查。
  • 如果服务端也参与了一部分校验,要及时回到 Web 主线。

建议工具

  • strings
  • http-framework-test
  • ghidra

输出要求

  • 关键资源清单
  • 校验主链
  • 关键常量/函数/模块
  • 下一步深挖方向

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.
