AI-generated overview

Guides authorized hardware and embedded interface security research: UART/JTAG discovery, debug pad triage and firmware extraction support.

What it does
This skill provides an instruction-only workflow for authorized hardware and embedded interface security research. It covers identifying debug interfaces such as UART, JTAG and SWD, triaging debug pads, reading boot logs, assessing secure boot or encrypted flash feasibility, and supporting offline firmware image extraction. It produces a checklist-driven procedure with tool suggestions and a handoff of extracted images to firmware analysis work.
When to use it
Use it when performing authorized physical testing of hardware or embedded devices and needing a structured approach to locating debug interfaces or extracting firmware. It fits lab work where physical access authorization and device ownership are confirmed and non-destructive, read-only probing is preferred.
Requirements
No scripts are shipped; it is instructions only. It references a companion reference document and related skills. Physical hardware access, test equipment such as a multimeter, USB-TTL adapter, logic analyzer, J-Link or CMSIS-DAP, and extraction tools such as binwalk or flashrom are described as part of the workflow.

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

text
□ 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 analyzerUART
J-Link / CMSIS-DAP调试

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?
