hunting-mobile-tapjacking-and-overlay-abuse skillA

hunting-mobile-tapjacking-and-overlay-abuse is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt mobile interface redressing, where another app draws over or intercepts a sensitive screen so the user acts on the attacker's terms without knowing it, approving a permission, confirming a transaction, or entering a secret while an overlay hides or fakes what they are really touching, because the sensitive screen does not detect that it is obscured, does not filter touches passed through an overlay, or does not bind the confirmation to what the user actually saw. Use when a mobile app prese.

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.
