hardware-security

Support authorized hardware security research by locating debug interfaces, recording pin assignments and voltage levels, and collecting boot logs. Assess interface locks and firmware extraction options, then hand extracted images to firmware analysis tools.

OriginalShow the original description

Use for authorized hardware and embedded interface security research including UART/JTAG discovery, debug pad triage, secure boot overview, and offline firmware extraction support.

See how to install

Good for

  • Locate UART, JTAG, and SWD debug interfaces
  • Collect and document boot logs
  • Assess secure boot and encrypted flash
  • Extract firmware images for further analysis

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 analyzerUART
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?
