metasploit-cursor-harness: Skill for Cursor

.cursor/skills/hardware-pentest/SKILL.md

hardware-pentest is a skill for Cursor from Suzu-Testing/metasploit-cursor-harness. It costs 46 tokens per session (1,340 once invoked), scanned A, original, MIT.

A guide for testing the security of physical devices, their hardware connections, and their firmware—the software stored on the device. It covers interfaces such as UART, JTAG, and SPI, which are used to communicate with device electronics.

In plain words
What is it for?
Use it for authorized testing of devices by examining documentation, extracting firmware, reading chips or flash storage, and analyzing the extracted files.
Why use it?
It provides a structured way to look for exposed debug access, unsafe firmware, hardcoded passwords, backdoors, and other weaknesses that cannot be found through software testing alone.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is Suzu-Testing/metasploit-cursor-harness's own configuration. It tells Cursor how to work on metasploit-cursor-harness itself, so it is not a mod to install elsewhere.

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-pentest 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 8d 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.

Hardware Pentest

Prerequisites

  • Physical access and hardware testing require explicit ROE authorization.
  • Device ownership or written permission for destructive extraction (chip-off, flash dump).
  • ESD-safe workspace and appropriate programmers (CH341A, Bus Pirate, J-Link).

Workflow

Task Progress:
- [ ] Confirm physical access scope and device inventory
- [ ] Gather OSINT (datasheets, FCC IDs, open-source components)
- [ ] Acquire firmware (download, OTA intercept, UART/JTAG/SPI dump)
- [ ] Extract and analyze filesystem (binwalk, strings)
- [ ] Identify hardcoded creds, backdoors, and attack surface

Phase 1: OSINT and reconnaissance

Information gathering

MSF: No direct module. Use OSINT sources and CLI triage.

CLI fallback:

strings firmware.bin | grep -iE "version|copyright|build"
binwalk firmware.bin
file firmware.bin
# FCC ID lookup, vendor firmware pages, Shodan/Censys for exposed interfaces

Phase 2: Physical access attacks

BIOS/UEFI and live access

MSF: No direct module. Use physical access techniques.

CLI fallback:

# Default BIOS passwords, CMOS battery reset, live USB boot
# SAM editing, single-user mode / init=/bin/sh on Linux

HID implants

MSF: No direct module. Use Rubber Ducky/BadUSB payloads.

CLI fallback:

# Rubber Ducky / BadUSB keystroke injection
# Bash Bunny for network attacks from USB form factor

Phase 3: Debug interface identification

UART

MSF: No direct module. Use serial console tools.

CLI fallback:

baudrate -f /dev/ttyUSB0
screen /dev/ttyUSB0 115200
# USB-TTL adapter, multimeter for GND/TX identification

JTAG

MSF: No direct module. Use OpenOCD.

CLI fallback:

openocd -f interface/jlink.cfg -f target/stm32f1x.cfg
# JTAGulator for pin identification

SPI flash

MSF: No direct module. Use flashrom.

CLI fallback:

flashrom -p ch341a_spi -r firmware_dump.bin
flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -r dump.bin

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-pentest is a skill published in the GitHub repository Suzu-Testing/metasploit-cursor-harness (3 stars, last pushed 14d ago), licensed MIT. It adds 46 tokens to every session and 1,340 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 2026-08-31.
