$npx -y skills add zhaoxuya520/reverse-skill --skill competition-windows-pivotInternal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for Kerberos, WinRM, SMB, RDP, Windows credential material, replayable tickets, delegation edges, and host-to-host pivot chains. Use when the user asks to replay Kerberos material, trace a WinRM, SMB, or

| 3 | 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. |

| 5 | Use this skill when the challenge path is dominated by host-to-host movement, replayable ticket material, or Windows privilege edges. |

| 9 | ## Quick Start |
| 10 | |
| 11 | 1. Compress the pivot into a concrete chain: foothold -> recovered artifact -> replay path -> pivot host -> resulting capability. |
| 12 | 2. Separate stored credential material from usable privilege. |
| 13 | 3. Keep host evidence, ticket evidence, and privilege effect on one timeline. |
| 14 | 4. Record the exact accepting service or host for every replayed artifact. |
| 15 | 5. Reproduce the smallest pivot that still proves the privilege edge. |
| 16 | |
| 17 | ## Workflow |
| 18 | |
| 19 | ### 1. Recover The Replay Material |
| 20 | |
| 21 | - Inspect SAM, SECURITY, SYSTEM, NTDS, DPAPI, LSA secrets, browser stores, PowerShell history, ETW, Sysmon, and event logs in the active path. |
| 22 | - Distinguish password, hash, ticket, cookie, vault blob, or gMSA material by where it can actually be used. |
| 23 | |
| 24 | ### 2. Trace The Pivot Chain |
| 25 | |
| 26 | - Map the protocol actually used: WinRM, SMB, RDP, WMI, admin shares, remote registry, or service control. |
| 27 | - When Kerberos matters, record SPN, delegation, PAC or group data, encryption type, and the accepting service. |
| 28 | - When AD edges matter, inspect ACLs, GPO links, SIDHistory, delegation, certificate templates, and replication rights. |
| 29 | |
| 30 | ### 3. Report The Edge |
| 31 | |
| 32 | - Keep the pivot path concrete and replayable. |
| 33 | - State what artifact crossed which boundary and what capability appeared on the destination host. |
| 34 | |
| 35 | ## Read This Reference |
| 36 | |
| 37 | - Load `references/windows-pivot.md` for the pivot checklist, Kerberos evidence block, and common replay mistakes. |
| 38 | - If the task is specifically about DPAPI masterkeys, browser or vault stores, protected blobs, or proving where a recovered DPAPI secret is accepted, prefer `$competition-dpapi-credential-chain`. |
| 39 | - If the task is specifically about LSASS memory, ticket caches, replayable session material, or host-resident credential extraction, prefer `$competition-lsass-ticket-material`. |
| 40 | - If the task is specifically about delegation edges, SPN trust, S4U flow, or which service accepts the delegated ticket, prefer `$competition-kerberos-delegation`. |
| 41 | - If the hard part is forced authentication, coercion primitives, relay targets, or the service that accepts relayed auth, prefer `$competition-relay-coercion-chain`. |
| 42 | |
| 43 | ## What To Preserve |
| 44 | |
| 45 | - Host names, logon IDs, SIDs, SPNs, ticket fields, service names, and event IDs |
| 46 | - Exact replay point and resulting logon session, token, or group change |
| 47 | - Raw host artifacts and derived timeline separately |
