competition-identity-windows

Lets your agent investigate identities and access in Windows networks. It can track permissions, analyze security logs, and understand how attackers move between systems.

What it does

This tool helps investigate how identities (users, accounts) move and gain access within Windows systems, especially in security challenges. It analyzes clues like tickets, credentials, and activities on Windows machines to understand attack chains.

When to use it

  • ✓Investigating how an attacker moved between computers.
  • ✓Analyzing how credentials were used or stolen.
  • ✓Understanding identity flow in corporate networks.

Example of what to ask your AI

“Analyze the lateral movement in the corporate network using the clues found.”

How it works

It works by connecting information from different sources, such as event logs, system files, and network data. By correlating these clues, it reconstructs the sequence of actions.

Installation

Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

In the terminal (Claude Code, Codex, Cursor), in your project folder:

npx skills add zhaoxuya520/reverse-skill --skill competition-identity-windows

Or download just the file:

Competition Identity Windows

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 revolves around identity flow, replayable credentials, Windows host artifacts, enterprise mail, or lateral movement.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Map the identity or pivot chain before diving into every host artifact.
  2. Separate credential possession from accepted privilege.
  3. Correlate identity evidence, host evidence, and mail evidence on one timeline.
  4. Keep tickets, SIDs, event IDs, mailbox rules, and pivot hosts in compact evidence blocks.
  5. Reproduce the privilege edge or mail effect from the smallest viable chain.

Workflow

1. Identity And AD

  • Trace principal origin, sync path, token or ticket minting, claims transformation, group resolution, and accepting service.
  • When Kerberos matters, record ticket type, SPN, delegation mode, PAC or group data, encryption type, and cache location.

2. Windows Host And Pivoting

  • Correlate SAM, SECURITY, SYSTEM, NTDS, DPAPI, LSA secrets, ETW, Sysmon, PowerShell, services, tasks, WMI, WinRM, SMB, and RDP as one pivot graph.
  • Express movement as a concrete chain: foothold -> recovered artifact -> replay path -> pivot host -> resulting capability.

3. Enterprise Messaging

  • Keep phishing lures, consent logs, mailbox rules, and identity-provider events tied together so the mail path and privilege path stay connected.

Read This Reference

  • Load references/identity-windows.md for the ticket, host, and enterprise-messaging checklist.
  • If the task is primarily a host-to-host pivot, Kerberos replay, or Windows privilege chain, prefer $competition-windows-pivot.
  • If the task is specifically about constrained delegation, unconstrained delegation, RBCD, S4U, or ticket-acceptance proof, prefer $competition-kerberos-delegation.
  • If the task is specifically about AD CS, certificate templates, EKUs, enrollment rights, PKINIT, or cert-based privilege, prefer $competition-ad-certificate-abuse.
  • If the task is specifically about OAuth or OIDC claims, callback flow, scopes, consent, or accepted login identity, prefer $competition-oauth-oidc-chain.
  • If the task is specifically about DPAPI masterkeys, vault blobs, browser or vault secrets, backup-key use, or protected-secret-to-access chains, prefer $competition-dpapi-credential-chain.
  • If the task is specifically about LSASS memory, ticket caches, LUID-linked material, DPAPI context, or replayable host credential artifacts, prefer $competition-lsass-ticket-material.
  • If the task is specifically about mailbox rules, forwarding, OAuth consent, delegate access, or transport-level mail abuse, prefer $competition-mailbox-abuse.
  • If the task is specifically about forced authentication, relay targets, or proving which service accepts relayed auth, prefer $competition-relay-coercion-chain.

What To Preserve

  • SIDs, SPNs, ticket fields, event IDs, mailbox rules, and replay points
  • Exact host-to-host pivot order and the service that accepts the credential or ticket
  • Raw artifacts, parsed summaries, and derived timelines as separate outputs
FAQ

What are 'tickets' and 'tokens'?

They are like digital passes that prove the identity of a user or service to access other resources on a network.

What is 'lateral movement'?

It's when an attacker, after gaining initial access to one system, moves to other systems on the same network to achieve their goals.

Do I need to know a lot about Windows to use this?

No, the tool simplifies the analysis, but understanding basic networking and security concepts helps interpret the results.
