hunting-firmware-secrets-and-debug-interfaces skillA

hunting-firmware-secrets-and-debug-interfaces is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt the attack surface a firmware image ships by mistake: a secret baked into the binary, a debug or diagnostic interface left enabled, a network service exposed by default, or a privileged command or update path reachable with no authentication. Covers a private key, symmetric key, or backdoor credential compiled into the image and used for authentication, a serial or on-chip debug console that drops to a privileged shell without auth, a management or plaintext service bound to every interface.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/hunting-firmware-secrets-and-debug-interfaces@git:20260821.57dfaf1
Exact content
mdr add unboundcompute/security-agent-skills/hunting-firmware-secrets-and-debug-interfaces@sha256:e44e26b2ce923f25

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
