auditing-mobile-biometric-and-local-auth-bypass skillA

auditing-mobile-biometric-and-local-auth-bypass is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit local authentication on a mobile app, where a biometric or device-passcode gate protects sensitive access but can be bypassed because the app trusts the result of the prompt rather than a key released by it, gates only the user interface while the protected data or action remains reachable, does not invalidate the key when enrolled biometrics change, or accepts a callback an attacker can forge on a controlled device. Use when a mobile app gates sensitive data or actions behind a biometric .

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/auditing-mobile-biometric-and-local-auth-bypass@git:20260908.e3ae18a
Exact content
mdr add unboundcompute/security-agent-skills/auditing-mobile-biometric-and-local-auth-bypass@sha256:bd5197fba1c98200

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.
