hunting-mutual-tls-and-service-identity-gaps skillA

hunting-mutual-tls-and-service-identity-gaps is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt for gaps in how a service establishes and verifies the identity of the peer calling it: a mutual-TLS endpoint that requests a client certificate but does not require or verify it, verification that checks the certificate chains to a trusted authority but never checks which identity it names, a trust anchor broad enough that any certificate it issued is accepted as any service, and an identity derived from a spoofable attribute (a header, a source IP) instead of the verified certificate. Cov.

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-mutual-tls-and-service-identity-gaps@git:20260829.b60f9b2
Exact content
mdr add unboundcompute/security-agent-skills/hunting-mutual-tls-and-service-identity-gaps@sha256:9ecc0bd1b54c6ddf

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.
