competition-lsass-ticket-material

competition-lsass-ticket-material is a skill for Codex from Asaiuta/reverse-workbench-skill. It costs 123 tokens per session (737 once invoked), scanned A, a copy of competition-lsass-ticket-material, MIT.

A specialized workflow for capture-the-flag exercises involving secrets and authentication data stored by Windows in LSASS, the process that manages logon credentials. It examines logon sessions, Kerberos tickets, DPAPI data, and related credential traces after a broader sandbox setup is active.

In plain words
What is it for?
Use it to inspect LSASS memory, recover Kerberos tickets or logon sessions, examine DPAPI-backed data and authentication packages, and prove whether extracted material can be replayed.
Why use it?
It helps separate raw credential traces from credentials that can actually be reused. It also keeps the evidence chain clear from the Windows artifact to an accepted privilege.

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-lsass-ticket-material 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 9d 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 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.

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.
