hunting-kerberos-and-ad-delegation-abuse skillA

hunting-kerberos-and-ad-delegation-abuse is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt for Active Directory Kerberos delegation configurations that let one identity act as another: a service account with unconstrained delegation that can impersonate any user who authenticates to it and reuse their ticket anywhere, constrained delegation configured so a service can request tickets for higher-privileged targets, resource-based delegation an attacker can set on an object they control to relay into it, a service account with a weak password exposed to Kerberoasting through its se.

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-kerberos-and-ad-delegation-abuse@git:20260903.19a7174
Exact content
mdr add unboundcompute/security-agent-skills/hunting-kerberos-and-ad-delegation-abuse@sha256:0898c5c8c9e6e4ec

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.
