firmware-pentest

firmware-pentest is a skill for Claude Code, Codex from DamonZS/PE-reverse-skill. It costs 215 tokens per session (4,063 once invoked), scanned A, original, no licence file.

A method for auditing embedded-device firmware, the software stored inside routers, cameras, and other connected hardware.

In plain words
What is it for?
It is for unpacking firmware, simulating devices, reproducing IoT vulnerabilities, and researching new embedded-device flaws.
Why use it?
It gives a path from an extracted firmware image through code analysis and emulation to testing a suspected weakness.

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

firmware-pentest scanned grade A with 2 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo emba -l ./logs -f ./firmware.bin -p ./scan-profiles/default-scan.emba

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

3 files 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.

firmware-pentest is a skill published in the GitHub repository DamonZS/PE-reverse-skill (20 stars, last pushed 13d ago), with no licence file. It adds 215 tokens to every session and 4,063 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
