Summary

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, r

10
11	1. Separate protected blob, masterkey, decrypting context, and final accepting service.
12	2. Record SID, user or machine context, masterkey path, vault or browser store, and target replay point before broad conclusions.
13	3. Keep DPAPI source artifact, unwrap step, plaintext secret, and acceptance edge in one chain.
14	4. Distinguish local user DPAPI, machine DPAPI, domain backup key use, and application-specific wrapping.
15	5. Reproduce the smallest DPAPI-to-accepted-access path that proves the decisive edge.

17	## Workflow
18
19	### 1. Map Protected Secret And DPAPI Context
20
21	- Record blob source, masterkey location, SID, protector scope, profile path, credential store, and any application wrapper such as browser encryption or vault metadata.
22	- Note whether the decisive value lives in Credential Manager, Vault, browser cookies, browser passwords, Wi-Fi profiles, RDP files, or custom app storage.
23	- Keep protected artifact, masterkey candidate, and account or machine context tied together.
24
25	### 2. Prove Unwrap And Acceptance
26
27	- Show how the secret is decrypted: user logon material, machine context, domain backup key, or another recovered protector.
28	- Record plaintext type, target host or service, replay method, and resulting session, token, or data access.
29	- Distinguish successful blob decryption from actual accepted access.
30
31	### 3. Reduce To The Decisive DPAPI Chain
32
33	- Compress the result to the smallest sequence: protected artifact -> masterkey or unwrap context -> plaintext secret -> accepted replay or access -> resulting capability.
34	- State clearly whether the decisive edge lives in masterkey recovery, DPAPI scope confusion, application wrapper handling, or the service that accepts the recovered secret.
35	- If the task broadens into generic LSASS ticket material or full Windows pivoting, hand back to the tighter host or pivot skill.
36
37	## Read This Reference
38
39	- Load `references/dpapi-credential-chain.md` for the blob checklist, masterkey checklist, and evidence packaging.
40
41	## What To Preserve
42
43	- Blob paths, masterkey paths, SIDs, protector scope, store names, and application wrapper details
44	- The exact accepting service or dataset unlocked by the recovered plaintext
45	- One minimal protected-artifact-to-accepted-access sequence that proves the edge
