硬體安全

用於授權的硬體與嵌入式介面安全研究,包括 UART/JTAG 偵測、除錯焊盤分類、安全開機概述與離線韌體提取支援。

硬體安全 是什麼?

此技能專注於硬體與嵌入式介面的安全研究,主要應用於授權的設備測試。它涵蓋了 UART、JTAG、SWD 等除錯介面的發現與分析,並支援透過引導日誌獲取 root shell、中斷開機流程,以及配合拆機進行 Flash 韌體提取。技能強調非破壞性優先原則,並在第一步要求確認物理接觸授權與設備歸屬,確保所有操作合法安全。支援的工具鏈包括 USB-TTL 邏輯分析儀、J-Link 除錯器、bus pirate 等,並可與 firmware-pentest 技能協作進行深度韌體分析。此技能同時提供安全開機與加密 Flash 的可行性評估,並要求結束時對鏡像進行雜湊保全與記錄介面電平。

說明文件

硬體 / 嵌入式介面安全

操作要求(讀完後立刻執行)

  1. 立刻: 確認物理接觸授權與設備歸屬
  2. 立刻: ESD/電源安全;預設唯讀探測
  3. 下一步: 聯合 firmware-pentest 做鏡像分析
  4. 執行: 外殼與除錯介面識別 → 控制台 → 提取

適用場景

  • UART / JTAG / SWD 除錯口發現
  • 啟動日誌、root shell、引導打斷
  • 配合拆機提取 Flash
  • 安全啟動/加密 Flash 的可行性評估(非破壞性優先)

工作流程

□ 拆解授權設備;拍照標註測試點
□ 萬用表找 GND/VCC/TX/RX;邏輯電平 1.8/3.3/5V
□ USB-TTL 唯讀日誌;記錄鮑率
□ JTAG:枚舉 IDCODE;評估是否鎖定
□ 提取鏡像 → 交接 firmware-pentest / ghidra

工具鏈

工具用途
USB-TTL / 邏輯分析儀UART
J-Link / CMSIS-DAP除錯
bus pirate / flipper(實驗室)多協定
binwalk / flashrom提取

不得: 未授權拆機/損壞他人設備

任務完成自檢

  • 是否記錄介面電平與引腳圖?
  • 鏡像是否雜湊保全?
  • 檢查清單?
