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…
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 Kerberos and AD delegation abuse: delegation lets a service become the user, so scope it Kerberos delegation exists so a front-end service can act as the user against a back-end service, a web app reaching a database as the logged-in user, for instance. That is useful and also a standing impersonation right, and the danger is entirely in its scope. Unconstrained delegation is the worst case: a service with it receives a forwardable ticket for every user who authenticates, caches it, and can replay that ticket against anything, so compromising one such service turns every user who touched it, up to and including a domain admin, into an identity the attacker can wear. Constrained delegation narrows the targets, but if the allowed targets include a higher-privileged service, or protocol transition lets the service request tickets for users who never authenticated to it, the constraint is a ramp. Resource-based constrained delegation moves the setting onto the target object, so an attacker who can write to an object they control can authorize their own delegation into it. And the credential side is just as live: a service account with a service principal name …

How to install
mdr add unboundcompute/security-agent-skills/hunting-kerberos-and-ad-delegation-abuse@sha256:0898c5c8c9e6e4ecThe line at the top of this page pins the label git:20260903.19a7174, 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.
