competition-lsass-ticket-material

Helps your agent extract secrets from Windows memory. Useful for recovering sensitive information from active sessions.

What it does

This tool helps find and prove how stolen login information (like passwords or tickets) can be used to access other systems. It focuses on extracting and verifying credentials that were stored in a computer's memory.

When to use it

  • ✓When you need to check if stolen credentials can be used to log in elsewhere.
  • ✓When investigating how an attack moved between computers using login information.
  • ✓To understand which parts of login information are actually useful to an attacker.

Example of what to ask your AI

“Check if stolen Kerberos tickets from LSASS memory can be used to access the email server.”

Ready-to-paste message

Use this skill to help me: https://github.com/zhaoxuya520/reverse-skill/blob/main/CTF-Sandbox-Orchestrator/competition-lsass-ticket-material/SKILL.md Read the SKILL.md file at that link and follow its instructions for my task.
How it works

The tool first finds and records all available login information on a system, like active sessions and tickets. Then, it tests where and how this information can be used to prove it's valid and useful.

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-lsass-ticket-material

Or download just the file:

Competition LSASS Ticket Material

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 host artifact lives in LSASS, ticket caches, or adjacent credential material and the hard part is proving what is replayable.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Separate raw credential material from actually usable replay edges.
  2. Record logon session, LUID, ticket cache, package, account, and target service before broad conclusions.
  3. Keep host artifact, extracted secret, replay attempt, and resulting acceptance in one chain.
  4. Distinguish password, hash, ticket, DPAPI secret, SSP residue, and token by where each can actually be used.
  5. Reproduce the smallest host-artifact-to-accepted-privilege path that proves the decisive edge.

Workflow

1. Map LSASS And Adjacent Credential State

  • Record logon sessions, LUIDs, ticket caches, package names, SSPs, DPAPI context, and any service-account material tied to the active path.
  • Note whether the decisive value is a TGT, service ticket, delegated ticket, DPAPI secret, plaintext, hash, or package-specific secret.
  • Keep host source, account context, and cache location tied together.

2. Prove Replay Or Acceptance

  • Show where the extracted material is accepted: SMB, WinRM, service ticket use, DPAPI unwrap, Schannel, or another host or service edge.
  • Record SPN, target host, logon session, ticket flags, encryption type, and resulting privilege or token change.
  • Distinguish material that is present from material that is actually replayable in this path.

3. Reduce To The Decisive Credential Chain

  • Compress the result to the smallest sequence: host artifact -> extracted material -> accepted replay or unwrap -> resulting capability.
  • State clearly whether the decisive edge lives in LSASS memory, ticket cache reuse, DPAPI context, or accepting service behavior.
  • If the task broadens into full host-to-host pivoting, hand back to the tighter Windows pivot skill.

Read This Reference

  • Load references/lsass-ticket-material.md for the session checklist, replay checklist, and evidence packaging.
  • If the task is specifically about DPAPI masterkeys, protected blobs, browser or vault stores, or proving which recovered DPAPI secret is accepted, prefer $competition-dpapi-credential-chain.

What To Preserve

  • LUIDs, session IDs, ticket types, SPNs, encryption types, package names, and cache or memory source
  • The exact accepting host or service and the resulting privilege or logon effect
  • One minimal host-artifact-to-replay sequence that proves the edge
FAQ

What is LSASS?

LSASS (Local Security Authority Subsystem Service) is an important process in Windows that handles security, including managing passwords and login tickets.

What are 'tickets'?

In Windows networks, tickets are like temporary passes that allow a user or service to access other resources without needing to type their password every time.

What does 'replayable' mean?

It means the stolen login information can be 'reused' to impersonate a legitimate user and access another system or service.
