Implementing Attack Path Validation
Overview
Attack path validation confirms whether theoretical paths from initial access to high-value targets are exploitable. Using BloodHound graph analysis combined with Atomic Red Team execution, purple teams test each link in privilege escalation and lateral movement chains to verify real-world exploitability and detection coverage.
Prerequisites
| Requirement | Install |
|---|---|
| BloodHound CE | docker compose -f docker-compose.yml up -d |
| SharpHound | BloodHound data collector |
| Invoke-AtomicRedTeam | PowerShell module |
| Python 3.10+ | For agent tooling |
| Neo4j | Graph database (included with BloodHound) |
| bloodhound-python | pip install bloodhound |
Key Concepts
Attack Path Structure
attack_path:
name: "Domain Admin via Kerberoasting"
start: "[email protected]"
target: "Domain Admins"
links:
- step: 1
from: "compromised-user"
to: "svc-sql"
technique: T1558.003 # Kerberoasting
description: "Kerberoast SPN-enabled service account"
- step: 2
from: "svc-sql"
to: "SQL-SERVER-01"
technique: T1021.001 # Remote Desktop
description: "RDP to SQL server with cracked creds"
- step: 3
from: "SQL-SERVER-01"
to: "Domain Admins"
technique: T1003.001 # LSASS dump
description: "Extract DA token from LSASS"
BloodHound Cypher Queries
// Find shortest path to Domain Admins
MATCH p=shortestPath((u:User {name:'[email protected]'})-[*1..]->(g:Group {name:'DOMAIN [email protected]'}))
RETURN p
// Find Kerberoastable users with admin paths
MATCH (u:User {hasspn:true})
MATCH p=shortestPath((u)-[*1..]->(g:Group {name:'DOMAIN [email protected]'}))
RETURN u.name, length(p) ORDER BY length(p)
// Find unconstrained delegation computers
MATCH (c:Computer {unconstraineddelegation:true})
RETURN c.name, c.operatingsystem
Workflow
1. Collect AD Data
# Run SharpHound collection
node agent.js collect-ad \
--domain CORP.LOCAL \
--method bloodhound-python \
--output collections/
# Or via SharpHound
# SharpHound.exe -c All --outputdirectory collections/
2. Identify Attack Paths
# Query BloodHound for attack paths
node agent.js find-paths \
--bloodhound-url http://localhost:8080 \
--start "[email protected]" \
--target "DOMAIN [email protected]" \
--output paths/da_paths.json
3. Validate Each Link
# Test each step in the attack path
node agent.js validate-path \
--path paths/da_paths.json \
--output results/path_validation.json
4. Measure Detection Coverage
# Check detections for each path step
node agent.js path-coverage \
--results results/path_validation.json \
--siem-url https://splunk:8089 \
--output reports/path_coverage.json

Verification
| Check | Method |
|---|---|
| AD data collected | BloodHound shows graph data |
| Paths identified | At least one path from start to target |
| Links validated | Each step tested with atomic or manual test |
| Coverage measured | Detection status for each path step |
