Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.\n\n## Overview\n\nBloodHound 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.\n\n\n## When to Use\n\n- When conducting security assessments that involve conducting internal reconnaissance with bloodhound ce\n- When following incident response procedures for related security events\n- When performing scheduled security testing or auditing activities\n- When validating security controls through hands-on testing\n\n## Prerequisites\n\n- Familiarity with red teaming concepts and tools\n- Access to a test or lab environment for safe execution\n- Python 3.8+ with required dependencies installed\n- Appropriate authorization for any testing activities\n\n## Objectives\n\n- Deploy BloodHound CE server using Docker Compose\n- Collect AD data using SharpHound v2 or BloodHound.py\n- Import collected data into BloodHound CE for graph analysis\n- Identify shortest attack paths from owned principals to Domain Admins\n- Discover ACL-based attack paths, Kerberoastable accounts, and delegation abuse\n- Execute custom Cypher queries for advanced attack path analysis\n- Generate attack path reports for engagement documentation\n\n## MITRE ATT&CK Mapping\n\n- **T1087.002** - Account Discovery: Domain Account\n- **T1069.002** - Permission Groups Discovery: Domain Groups\n- **T1482** - Domain Trust Discovery\n- **T1615** - Group Policy Discovery\n- **T1018** - Remote System Discovery\n- **T1033** - System Owner/User Discovery\n- **T1016** - System Network Configuration Discovery\n\n## Workflow\n\n### Phase 1: BloodHound CE Deployment\n1. Deploy BloodHound CE using Docker Compose:\n   ```bash\n   curl -L https://ghst.ly/getbhce -o docker-compose.yml\n   docker compose pull\n   docker compose up -d\n   ```\n2. Access the web interface at https://localhost:8080\n3. Log in with the default admin credentials (displayed in Docker logs):\n   ```bash\n   docker compose logs | grep \"Initial Password\"\n   ```\n4. Change the default admin password immediately\n\n### Phase 2: Data Collection with SharpHound v2\n1. Transfer SharpHound v2 to the compromised Windows host:\n   ```powershell\n   # Execute full collection\n   .\\SharpHound.exe -c All --outputdirectory C:\\Temp\n\n   # DCOnly collection (LDAP only, stealthier)\n   .\\SharpHound.exe -c DCOnly\n\n   # Session collection for logged-on user mapping\n   .\\SharpHound.exe -c Session --loop --loopduration 02:00:00\n\n   # Collect from specific domain\n   .\\SharpHound.exe -c All -d child.domain.local\n   ```\n2. Alternative: Use BloodHound.py from Linux:\n   ```bash\n   bloodhound-python -u user -p 'Password123' -d domain.local -ns 10.10.10.1 -c All\n   ```\n3. Exfiltrate the generated ZIP file to the analysis workstation\n\n### Phase 3: Data Import and Initial Analysis\n1. Upload collected data via the BloodHound CE web interface (File Ingest)\n2. Mark compromised accounts as \"Owned\" in the interface\n3. Run built-in analysis queries:\n   - Shortest Path to Domain Admin\n   - Kerberoastable Users with Path to DA\n   - AS-REP Roastable Users\n   - Users with DCSync Rights\n   - Computers with Unconstrained Delegation\n\n### Phase 4: Custom Cypher Queries\n1. Execute custom Cypher queries in the BloodHound CE search bar:\n   ```cypher\n   // Find shortest path from owned principals to Domain Admins\n   MATCH p=shortestPath((n {owned:true})-[*1..]->(m:Group {name:\"DOMAIN ADMINS@DOMAIN.LOCAL\"}))\n   RETURN p\n\n   // Find Kerberoastable users with path to DA\n   MATCH (u:User {hasspn:true})\n   MATCH p=shortestPath((u)-[*1..]->(g:Group {name:\"DOMAIN ADMINS@DOMAIN.LOCAL\"}))\n   RETURN p\n\n   // Find computers with sessions of DA members\n   MATCH (c:Computer)-[:HasSession]->(u:User)-[:MemberOf*1..]->(g:Group {name:\"DOMAIN ADMINS@DOMAIN.LOCAL\"})\n   RETURN c.name, u.name\n\n   // Find ACL-based attack paths (GenericAll, WriteDACL, GenericWrite)\n   MATCH p=(u:User)-[:GenericAll|GenericWrite|WriteDacl|WriteOwner|ForceChangePassword*1..]->(t)\n   WHERE u.owned = true\n   RETURN p\n\n   // Find users who can DCSync\n   MATCH (u)-[:MemberOf*0..]->()-[:DCSync|GetChanges|GetChangesAll*1..]->(d:Domain)\n   RETURN u.name, d.name\n\n   // Find computers with LAPS but readable by non-admins\n   MATCH (c:Computer {haslaps:true})\n   MATCH p=(u:User)-[:ReadLAPSPassword]->(c)\n   RETURN p\n   ```\n\n### Phase 5: Attack Path Prioritization\n1. Score identified attack paths by:\n   - Number of hops (shorter = higher priority)\n   - Stealth requirements (avoid noisy techniques)\n   - Tool availability for each hop\n   - Likelihood of detection at each step\n2. Create an execution plan for the highest-priority paths\n3. Identify required tools for each step in the chain\n4. Plan OPSEC considerations for each technique\n\n## Tools and Resources\n\n| Tool | Purpose | Platform |\n|------|---------|----------|\n| BloodHound CE | Web-based graph analysis platform | Docker |\n| SharpHound v2 | AD data collection (.NET, for CE) | Windows |\n| BloodHound.py | AD data collection (Python) | Linux |\n| AzureHound | Azure AD / Entra ID data collection | Cross-platform |\n| PlumHound | Automated BloodHound reporting | Python |\n| BloodHound Query Library | Community Cypher query repository | Web |\n\n## Key Attack Path Types\n\n| Path Type | Description | Example |\n|-----------|-------------|---------|\n| ACL Abuse | Exploit misconfigured ACLs | GenericAll on DA group |\n| Kerberoasting | Crack service account passwords | SPN account → DA |\n| AS-REP Roasting | Attack accounts without pre-auth | No-preauth user → password crack |\n| Delegation Abuse | Exploit unconstrained/constrained delegation | Computer → impersonate DA |\n| GPO Abuse | Modify GPOs applied to privileged OUs | GPO write → code execution on DA |\n| Session Hijack | Leverage DA sessions on compromised hosts | Admin session → token theft |\n\n## Validation Criteria\n\n- [ ] BloodHound CE deployed and accessible\n- [ ] SharpHound v2 data collected from all domains in scope\n- [ ] Data successfully imported into BloodHound CE\n- [ ] Owned principals marked in the interface\n- [ ] Shortest paths to Domain Admin identified\n- [ ] ACL-based attack paths documented\n- [ ] Kerberoastable and AS-REP roastable accounts listed\n- [ ] Custom Cypher queries executed for advanced analysis\n- [ ] Attack paths prioritized by feasibility and stealth\n- [ ] Report generated with all identified paths and evidence\n\n## Other files in this skill\n\n- [LICENSE](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/LICENSE)\n- [assets/template.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/assets/template.md)\n- [references/api-reference.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/references/api-reference.md)\n- [references/standards.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/references/standards.md)\n- [references/workflows.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/references/workflows.md)\n- [scripts/agent.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/scripts/agent.py)\n- [scripts/process.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/conducting-internal-reconnaissance-with-bloodhound-ce/scripts/process.py)\n\n## assets/template.md (verbatim)\n\n# BloodHound CE Reconnaissance Report Template\n\n## Engagement Details\n\n| Field | Value |\n|-------|-------|\n| Engagement Name | |\n| Target Domain(s) | |\n| Collection Date | |\n| BloodHound CE Version | |\n| SharpHound Version | |\n\n## Collection Summary\n\n| Metric | Count |\n|--------|-------|\n| Users | |\n| Computers | |\n| Groups | |\n| GPOs | |\n| OUs | |\n| Domains | |\n| Trusts | |\n| Sessions | |\n\n## Attack Paths Identified\n\n| #
