hardware-security

hardware-security is a skill for Claude Code, Codex from xAmirHamza77/ReverseOps-Skill. It costs 33 tokens per session (415 once invoked), scanned A, original, MIT.

A guide to investigating security interfaces on owned or authorized hardware and embedded devices. It covers UART, JTAG, SWD, boot logs, debug pads, secure boot, and offline firmware extraction.

In plain words
What is it for?
Use it to identify test points, read boot logs, inspect debug locks, assess secure-boot protections, and extract firmware for further analysis.
Why use it?
It helps reveal how a device starts, exposes debugging access, and protects its firmware without beginning with destructive probing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hardware-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Hardware / Embedded Interface Security

ACTION REQUIRED (execute immediately after reading)

  1. NOW: Confirm physical-access authorization and device ownership
  2. NOW: ESD/power safety; default to read-only probing
  3. NEXT: Combine with firmware-pentest for image analysis
  4. ACT: Enclosure and debug-interface identification → consoles → extraction

Applicable Scenarios

  • UART / JTAG / SWD debug-port discovery
  • Boot logs, root shell, interrupting the bootloader
  • Flash extraction in coordination with device teardown
  • Feasibility assessment of secure boot / encrypted Flash (non-destructive methods first)

Workflow

□ Teardown of authorized devices; photograph and label test points
□ Use a multimeter to find GND/VCC/TX/RX; logic levels 1.8/3.3/5V
□ USB-TTL for read-only logs; record the baud rate
□ JTAG: enumerate IDCODE; assess whether it is locked
□ Extract images → hand off 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

References

  • references/debug-interface-triage.md
  • ../firmware-pentest/ ../ot-ics/

Routing Context

Upstream: MASTER R34
MUST NOT: tear down or damage others' devices without authorization

Task Completion Checklist

  • Were interface levels and pinouts documented?
  • Were images hash-preserved?
  • Checklist?

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hardware-security is a skill published in the GitHub repository xAmirHamza77/ReverseOps-Skill (4 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 415 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
