Hardware / Embedded Interface Security

ACTION REQUIRED (Execute Immediately After Reading)

```
NOW
```
: Confirm physical access authorization and device ownership
```
NOW
```
: ESD/Power Supply Safety; Default to Read-Only Probing
```
NEXT
```
: Collaborate with firmware-pentest for image analysis
```
ACT
```
: Enclosure and Debug Interface Identification → Consoles → Extraction

Application Scenarios

UART/JTAG/SWD Debug Port Discovery
Boot Logs, Root Shell, Boot Interruption
Flash Extraction with Device Teardown
Feasibility Assessment of Secure Boot/Encrypted Flash (Non-Destructive Priority)

Workflow

text

□ Disassemble authorized device; Take photos and mark test points
□ Use multimeter to locate GND/VCC/TX/RX; Logic levels 1.8/3.3/5V
□ USB-TTL read-only logging; Record baud rate
□ JTAG: Enumerate IDCODE; Evaluate if locked
□ Extract image → Hand over to firmware-pentest / ghidra

Toolchain

Tool	Purpose
USB-TTL / logic analyzer	UART
J-Link / CMSIS-DAP	Debugging
bus pirate / flipper (Lab)	Multi-protocol
binwalk / flashrom	Extraction

Routing Context

Upstream: MASTER R34
MUST NOT: Unauthorized teardown/damage to others' devices

Task Completion Self-Check

Have interface levels and pin diagrams been recorded?
Has the image been hashed and preserved?
Checklist completed?
