Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for DPAPI masterkeys, vault blobs, browser credential stores, protected secrets, domain backup keys, and secret-to-acceptance replay chains. Use when the user asks to inspect DPAPI blobs or masterkeys, recover browser or vault credentials, trace DPAPI context or backup-key use, or explain how protected Windows secrets become accepted access or privilege. Use only after `$ctf-sandbox-orchestrator` has already…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Competition Dpapi Credential Chain Use this skill only as a downstream specialization after `$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 Windows secret is DPAPI-protected and the hard part is proving which context unwraps it and where the plaintext is accepted. Reply in Simplified Chinese unless the user explicitly requests English. ## Quick Start 1. Separate protected blob, masterkey, decrypting context, and final accepting service. 2. Record SID, user or machine context, masterkey path, vault or browser store, and target replay point before broad conclusions. 3. Keep DPAPI source artifact, unwrap step, plaintext secret, and acceptance edge in one chain. 4. Distinguish local user DPAPI, machine DPAPI, domain backup key use, and application-specific wrapping. 5. Reproduce the smallest DPAPI-to-accepted-access path that proves the decisive edge. ## Workflow ### 1. Map Protected Secret And DPAPI Context …

How to install
mdr add novaestellar/novahaku/competition-dpapi-credential-chain@sha256:8131c4a320164fbfThe 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.
