Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for AD CS, certificate templates, enrollment rights, EKUs, SAN controls, PKINIT, certificate mapping, and cert-based privilege paths. Use when the user asks about ESC-style abuse, certificate templates, enrollment agents, EKUs, SAN or subject controls, smartcard or PKINIT logon, CA policy, or how an issued cert turns into accepted privilege. Use only after `$ctf-sandbox-orchestrator` has already established sandbox…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Competition AD Certificate Abuse Use this skill only as a downstream specialization after `$ctf-sandbox-orchestrator` is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to `$ctf-sandbox-orchestrator` first. Use this skill when the decisive identity edge is certificate-based and the hard part is proving how a template or CA policy turns into accepted privilege. Reply in Simplified Chinese unless the user explicitly requests English. ## Quick Start 1. Identify the CA, template, enrolling principal, and accepting service before diving into every certificate detail. 2. Separate template enrollability from cert-based authentication or privilege acceptance. 3. Record EKUs, subject or SAN controls, issuance requirements, enrollment rights, and mapping behavior in compact blocks. 4. Tie the issued cert to one accepted path: PKINIT, Schannel, LDAPS, WinRM, or another mapped service. 5. Reproduce the smallest certificate issuance-to-acceptance chain that yields the decisive privilege. ## Workflow ### 1. Map CA And Template Trust …

How to install
mdr add novaestellar/novahaku/competition-ad-certificate-abuse@sha256:40e97ef2d25ad48aThe line at the top of this page pins the label git:20260925.9330cc6, 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.
