hunting-ios-keychain-and-data-protection-gaps skillB

hunting-ios-keychain-and-data-protection-gaps is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt at-rest exposure of secrets on iOS, where a credential, token, or sensitive value is stored with a keychain accessibility class or a data-protection class weaker than it needs, so it is readable when the device is locked, survives into a device backup, or is reachable by another app or after theft, because the item is marked always-accessible, is not restricted to this device, or the file protection lets it be read outside an unlocked session. Use when reviewing how an app stores secrets an.

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-ios-keychain-and-data-protection-gaps@git:20260908.e3ae18a
Exact content
mdr add unboundcompute/security-agent-skills/hunting-ios-keychain-and-data-protection-gaps@sha256:99948695bbbe7b1b

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.
