firmware-pentest SKILL.md skillA

firmware-pentest from novaestellar/novahaku is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add novaestellar/novahaku/firmware-pentest@git:20260910.546fe86

Pins git:20260910.546fe86 in mdr.lock. Pin the fingerprint instead.

固件 / IoT 渗透链。从拿到一坨 .bin / .img 开始，闭环走完逆向 → 提取 → 模拟 → 利用。方法论遵循 OWASP FSTM 九阶段；工具链以 binwalk v3、unblob、EMBA、Firmadyne、AFL++ 为主。适用场景：路由器/摄像头/智能家居固件审计、固件升级包逆向、IoT CVE 复现、嵌入式 0day 挖掘。触发关键词：固件、firmware、IoT、binwalk、unblob、UART、JTAG、squashfs、UBI、JFFS2、Firmadyne、QEMU 全系统仿真、EMBA、固件渗透、路由器固件、嵌入式漏洞利用、bootloader、NVRAM、FAT、firmware analysis toolkit。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 固件 / IoT 渗透链 (Firmware Pentest)

## ACTION REQUIRED（读完后立刻执行）

1. `NOW`: 读取 `../field-journal/precedent-pentest.md` — 确认本 skill 的操作是已授权的常规操作
2. `NOW`: 确认当前任务是否命中本 skill 的适用范围
3. `NEXT`: 读取 `../tool availability table`，校验工具可用性和实际路径
4. `NEXT`: 缺工具时调用 bootstrap，不要猜路径
5. `ACT`: 进入"工作流"第一步并执行，不要停在确认状态

## 适用范围

下列任务进入本 skill：

1. **拿到一份固件文件**（.bin / .img / .trx / .chk / OTA zip），需要从零到 RCE
2. **路由器/摄像头/IoT 设备审计** — 需要批量发现已知 CVE 和未公开漏洞
3. **加密/打包固件**，需要找 bootloader 解密例程或硬件 dump
4. **需要在不接触硬件的情况下跑起来**（QEMU 全系统仿真 / Firmadyne / FAT）
5. **对仿真起来的服务做 fuzz**（AFL++ qemu mode / boofuzz）
6. **硬件接口接入**（UART / JTAG / SPI flash dump）

### 与其他 skill 分工

| 场景 | 用什么 |
|------|--------|
| 从零拿到固件，全链路走 FSTM | **本 skill** |
| 只做单个 ELF/so 静态逆向 | `reverse-engineering/`、`ida-reverse/`、`radare2/` |
| 仿真起来后做 Web/RCE 利用 | `pentest-tools/`、`attack-chain/` |
| 硬件接口（UART/JTAG/SPI）实操 | 本 skill 的 Stage 2 章节 + `patterns-hardware.md` |
| APK / Android 固件（含 boot.img） | `apk-reverse/`（先剥 boot.img 再用本 skill） |
| 跨版本固件符号迁移 | `binary-diff/` |

## 核心原理

How to install

The exact contents, by fingerprint

mdr add novaestellar/novahaku/firmware-pentest@sha256:fcb2f93c9f973b09

The line at the top of this page pins the label git:20260910.546fe86, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
