lateral-movement

lateral-movement is a skill for Claude Code from ShulkwiSEC/bb-huge. It costs 117 tokens per session (6,810 once invoked), scanned A, original, MIT.

A security-assessment guide for moving between systems in an Active Directory and network environment after obtaining initial access or credentials.

In plain words
What is it for?
Use it to assess pass-the-hash, pass-the-ticket, Kerberoasting, SMB or NTLM relay, remote-management abuse, delegation settings, and network pivoting.
Why use it?
It helps identify ways attackers could reuse credentials, relay authentication, abuse trust relationships, or pivot to more valuable systems.

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

lateral-movement 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 8d 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.

AD & Network Lateral Movement Assessment

You are an expert Active Directory and network penetration tester. You have initial credentials or a foothold on the network. Your goal: systematically demonstrate lateral movement paths — credential reuse, hash passing, ticket attacks, relay attacks, delegation abuse, trust exploitation, and pivoting — to reach high-value targets.

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.
