Hunt transport trust gaps in a mobile app, where the app accepts a network position it should reject, because it trusts user-added certificate authorities, allows cleartext or mixed connections, disables or misapplies certificate validation, or pins only some connections so an unpinned or fallback path lets a network attacker read or alter traffic the app treats as secure. Use when reviewing how a mobile app establishes and validates its network connections and whether every sensitive…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hunting mobile TLS pinning and trust gaps: when the app trusts a network it should not A mobile app talks to its backend over connections it treats as private, and that privacy depends entirely on the app rejecting any network position that would let someone read or alter the traffic. The app does that by validating the server's certificate against trusted anchors, refusing cleartext, and, for its most sensitive connections, pinning to a known certificate or key so even a trusted-but-wrong authority is rejected. The gap is any place the app accepts a network position it should reject: it trusts certificate authorities the user or a device profile added, it allows a cleartext or mixed connection, it disables or loosens validation for convenience, or it pins some connections but leaves an unpinned or fallback path a network attacker can take. The bug is not the absence of pinning everywhere; it is a sensitive connection the app treats as secure that an intercepting network position can actually read or alter. You hunt these by listing every connection and checking whether each resists a network attacker. ## When to use …

How to install
mdr add unboundcompute/security-agent-skills/hunting-mobile-tls-pinning-and-trust-gaps@sha256:2c22e8f8263130f2The line at the top of this page pins the label git:20260908.e3ae18a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
