hardware-security

hardware-security is a skill for Claude Code, Codex from zhaoxuya520/reverse-skill. It costs 33 tokens per session (459 once invoked), scanned A, original, MIT.

A guide to authorized security research on hardware and embedded devices, including serial consoles, debug pins, secure boot, and firmware extraction. It emphasizes identifying interfaces and collecting data without damaging the device.

In plain words
What is it for?
Use it to identify UART, JTAG, and SWD connections, capture boot logs, assess whether debugging is locked, extract firmware images, and pass them to firmware or binary analysis.
Why use it?
Debug ports and boot interfaces can expose logs, shells, or firmware, but probing them requires correct voltage levels, wiring, permissions, and evidence handling. The guide provides a cautious process for this work.

About the project

Reverse Skill is a routing package for AI coding agents that selects appropriate reverse-engineering, penetration-testing, and security-research methods and tools for a given target. It is used for tasks involving APKs, binaries, frontend JavaScript, packet captures, CTF challenges, and authorized penetration testing. Its catalogue add-ons provide the skills and instructions that guide these workflows.

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

hardware-security 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 3d 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

Hardware / Embedded Interface Security

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 确认物理接触授权与设备归属
  2. NOW: ESD/电源安全;默认只读探测
  3. NEXT: 联合 firmware-pentest 做镜像分析
  4. ACT: 外壳与调试接口识别 → consoles → 提取

适用场景

  • UART / JTAG / SWD 调试口发现
  • 启动日志、root shell、引导打断
  • 配合拆机提取 Flash
  • 安全启动/加密 Flash 的可行性评估(非破坏性优先)

工作流

□ 拆解授权设备;拍照标注测试点
□ 万用表找 GND/VCC/TX/RX;逻辑电平 1.8/3.3/5V
□ USB-TTL 只读日志;记录波特率
□ JTAG:枚举 IDCODE;评估是否锁定
□ 提取镜像 → 交接 firmware-pentest / ghidra

工具链

工具 用途
USB-TTL / logic analyzer UART
J-Link / CMSIS-DAP 调试
bus pirate / flipper(实验室) 多协议
binwalk / flashrom 提取

参考

  • references/debug-interface-triage.md
  • ../firmware-pentest/ ../ot-ics/

路由上下文

上游: MASTER R34
MUST NOT: 未授权拆机/损坏他人设备

任务完成自检

  • 是否记录接口电平与引脚图?
  • 镜像是否哈希保全?
  • Checklist?
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

hardware-security is a skill published in the GitHub repository zhaoxuya520/reverse-skill (34,719 stars, last pushed 3d ago), licensed MIT. It adds 33 tokens to every session and 459 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
