95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Systematic hunt for hardcoded credentials, API keys, certificates, and default passwords in extracted IoT firmware. Covers /etc/shadow and passwd parsing, busybox httpd configs, telnet/dropbear stanzas, MQTT/cloud API key extraction, and cross-referencing against known default-credential databases.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'hardcoded-creds' ] || [ -L ~/.agents/skills/'hardcoded-creds' ]; then echo 'A skill folder named hardcoded-creds already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/BitterSecurity/Decepticon' "$d" && git -C "$d" checkout --quiet 'bdb1016c93ed687f61ac57481da298c25a47c8f5' -- 'packages/decepticon/decepticon/skills/standard/iot/hardcoded-creds' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/decepticon/decepticon/skills/standard/iot/hardcoded-creds' ~/.agents/skills/'hardcoded-creds' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'hardcoded-creds' ~/.claude/skills/'hardcoded-creds' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
