Conducting Internal Reconnaissance with BloodHound CE
Overview
BloodHound Community Edition (CE) is a modern, web-based Active Directory reconnaissance platform developed by SpecterOps that uses graph theory to reveal hidden relationships and attack paths within AD environments. Unlike the legacy BloodHound application, BloodHound CE uses a PostgreSQL backend with a dedicated graph database, providing improved performance, a modern web UI, and enhanced API capabilities. Red teams use BloodHound CE to collect AD objects, ACLs, sessions, group memberships, and trust relationships, then visualize attack paths from compromised low-privileged accounts to high-value targets like Domain Admins. The SharpHound collector (v2 for CE) gathers data from Active Directory, while AzureHound collects from Azure AD / Entra ID environments.
Objectives
- Deploy BloodHound CE server using Docker Compose
- Collect AD data using SharpHound v2 or BloodHound.py
- Import collected data into BloodHound CE for graph analysis
- Identify shortest attack paths from owned principals to Domain Admins
- Discover ACL-based attack paths, Kerberoastable accounts, and delegation abuse
- Execute custom Cypher queries for advanced attack path analysis
- Generate attack path reports for engagement documentation

Implementation Steps
Phase 1: BloodHound CE Deployment
- Deploy BloodHound CE using Docker Compose:
```bash
curl -L https://ghst.ly/getbhce -o docker-compose.yml
docker compose pull
docker compose up -d
```
- Access the web interface at https://localhost:8080
- Log in with the default admin credentials (displayed in Docker logs):
```bash
docker compose logs | grep "Initial Password"
```
- Change the default admin password immediately
Phase 2: Data Collection with SharpHound v2
- Transfer SharpHound v2 to the compromised Windows host:
```powershell
# Execute full collection
.\SharpHound.exe -c All --outputdirectory C:\Temp
# DCOnly collection (LDAP only, stealthier)
.\SharpHound.exe -c DCOnly
# Session collection for logged-on user mapping
.\SharpHound.exe -c Session --loop --loopduration 02:00:00
# Collect from specific domain
.\SharpHound.exe -c All -d child.domain.local
```
- Alternative: Use BloodHound.py from Linux:
```bash
bloodhound-python -u user -p 'Password123' -d domain.local -ns 10.10.10.1 -c All
```
- Exfiltrate the generated ZIP file to the analysis workstation
Phase 3: Data Import and Initial Analysis
- Upload collected data via the BloodHound CE web interface (File Ingest)
- Mark compromised accounts as "Owned" in the interface
- Run built-in analysis queries:
- Shortest Path to Domain Admin
- Kerberoastable Users with Path to DA
- AS-REP Roastable Users
- Users with DCSync Rights
- Computers with Unconstrained Delegation
Phase 4: Custom Cypher Queries
- Execute custom Cypher queries in the BloodHound CE search bar:
```cypher
// Find shortest path from owned principals to Domain Admins
MATCH p=shortestPath((n {owned:true})-[*1..]->(m:Group {name:"DOMAIN ADMINS@DOMAIN.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@DOMAIN.LOCAL"}))
RETURN p
// Find computers with sessions of DA members
MATCH (c:Computer)-[:HasSession]->(u:User)-[:MemberOf*1..]->(g:Group {name:"DOMAIN ADMINS@DOMAIN.LOCAL"})
RETURN c.name, u.name
// Find ACL-based attack paths (GenericAll, WriteDACL, GenericWrite)
MATCH p=(u:User)-[:GenericAll|GenericWrite|WriteDacl|WriteOwner|ForceChangePassword*1..]->(t)
WHERE u.owned = true
RETURN p
// Find users who can DCSync
MATCH (u)-[:MemberOf0..]->()-[:DCSync|GetChanges|GetChangesAll1..]->(d:Domain)
RETURN u.name, d.name
// Find computers with LAPS but readable by non-admins
MATCH (c:Computer {haslaps:true})
MATCH p=(u:User)-[:ReadLAPSPassword]->(c)
RETURN p
```
Phase 5: Attack Path Prioritization
- Score identified attack paths by:
- Number of hops (shorter = higher priority)
- Stealth requirements (avoid noisy techniques)
- Tool availability for each hop
- Likelihood of detection at each step
- Create an execution plan for the highest-priority paths
- Identify required tools for each step in the chain
- Plan OPSEC considerations for each technique

Compliance Framework Mapping
This skill supports compliance evidence collection across multiple frameworks:
- SOC 2: CC4.1 (Monitoring & Evaluation), CC7.1 (Monitoring)
- ISO 27001: A.14.2 (Secure Development), A.18.2 (Information Security Reviews)
- NIST 800-53: CA-8 (Penetration Testing), RA-5 (Vulnerability Scanning)
- NIST CSF: ID.RA (Risk Assessment), PR.IP (Information Protection)
Claw GRC Tip: When this skill is executed by a registered agent, compliance evidence is automatically captured and mapped to the relevant controls in your active frameworks.
Deploying This Skill with Claw GRC
Agent Execution
Register this skill with your Claw GRC agent for automated execution:
# Install via CLI
npx claw-grc skills add conducting-internal-reconnaissance-with-bloodhound-ce
# Or load dynamically via MCP
grc.load_skill("conducting-internal-reconnaissance-with-bloodhound-ce")
Audit Trail Integration
When executed through Claw GRC, every step of this skill generates tamper-evident audit records:
- SHA-256 chain hashing ensures no step can be modified after execution
- Evidence artifacts (configs, scan results, logs) are automatically attached to relevant controls
- Trust score impact โ successful execution increases your agent's trust score
Continuous Compliance
Schedule this skill for recurring execution to maintain continuous compliance posture. Claw GRC monitors for drift and alerts when re-execution is needed.
