competition-windows-pivot

competition-windows-pivot is a skill for Codex from Asaiuta/reverse-workbench-skill. It costs 115 tokens per session (732 once invoked), scanned A, a copy of competition-windows-pivot, MIT.

A specialized guide for capture-the-flag (CTF) exercises involving movement between Windows machines using Kerberos tickets, remote services, and recovered credentials. It is meant to run after a broader sandbox setup has been established.

In plain words
What is it for?
Use it to trace and reproduce Windows pivots through WinRM, SMB, or RDP, including ticket replay, delegation paths, and host-to-host access.
Why use it?
It helps separate saved credential material from permissions that can actually be used, while keeping the evidence for each machine, ticket, and privilege change connected.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

competition-windows-pivot scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Competition Windows Pivot

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 challenge path is dominated by host-to-host movement, replayable ticket material, or Windows privilege edges.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Compress the pivot into a concrete chain: foothold -> recovered artifact -> replay path -> pivot host -> resulting capability.
  2. Separate stored credential material from usable privilege.
  3. Keep host evidence, ticket evidence, and privilege effect on one timeline.
  4. Record the exact accepting service or host for every replayed artifact.
  5. Reproduce the smallest pivot that still proves the privilege edge.

Workflow

1. Recover The Replay Material

  • Inspect SAM, SECURITY, SYSTEM, NTDS, DPAPI, LSA secrets, browser stores, PowerShell history, ETW, Sysmon, and event logs in the active path.
  • Distinguish password, hash, ticket, cookie, vault blob, or gMSA material by where it can actually be used.

2. Trace The Pivot Chain

  • Map the protocol actually used: WinRM, SMB, RDP, WMI, admin shares, remote registry, or service control.
  • When Kerberos matters, record SPN, delegation, PAC or group data, encryption type, and the accepting service.
  • When AD edges matter, inspect ACLs, GPO links, SIDHistory, delegation, certificate templates, and replication rights.

3. Report The Edge

  • Keep the pivot path concrete and replayable.
  • State what artifact crossed which boundary and what capability appeared on the destination host.

Read This Reference

  • Load references/windows-pivot.md for the pivot checklist, Kerberos evidence block, and common replay mistakes.
  • 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.
  • If the task is specifically about LSASS memory, ticket caches, replayable session material, or host-resident credential extraction, prefer $competition-lsass-ticket-material.
  • If the task is specifically about delegation edges, SPN trust, S4U flow, or which service accepts the delegated ticket, prefer $competition-kerberos-delegation.
  • If the hard part is forced authentication, coercion primitives, relay targets, or the service that accepts relayed auth, prefer $competition-relay-coercion-chain.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
