Active Directory and Entra ID reconnaissance reveals privilege-escalation chains that lead to full domain/tenant compromise. Use only against environments you own or have explicit written authorization (rules of engagement) to test. Unauthorized use violates the Computer Fraud and Abuse Act and equivalent laws.\n\n## Overview\n\nBloodHound Community Edition (CE) is SpecterOps's graph-based attack-path-management platform. It models security principals (users, computers, groups, OUs, GPOs, Entra ID users/groups/apps/roles) as nodes and the permissions, group memberships, sessions, trusts, and ACLs between them as edges. By framing Active Directory and Entra ID as a directed graph, BloodHound turns the question \"can this low-privileged account reach Domain Admins / Global Administrator?\" into a shortest-path query that finds escalation chains a human reviewer would miss.\n\nBloodHound CE replaced the legacy Neo4j-only BloodHound with a containerized stack: a Go API server, a PostgreSQL relational store, and a Neo4j graph database, all behind a modern web UI and REST API. Data is gathered by two collectors maintained by SpecterOps:\n\n- **SharpHound** (the CE/.NET collector, run on or against a domain-joined Windows host) gathers on-prem AD: objects, group membership, ACLs, sessions, local-admin rights, trusts, GPOs, certificate services (ADCS), and LAPS readability. It emits a ZIP of JSON.\n- **AzureHound** (a cross-platform Go binary) gathers Entra ID and Azure Resource Manager data via the Microsoft Graph and Azure REST APIs: users, groups, app registrations, service principals, directory roles, subscription/role assignments, and key vaults. It emits a single JSON file.\n\nAs of recent CE releases, when both an AD domain and its synced Entra ID tenant are ingested, BloodHound automatically renders **Hybrid Attack Paths** — chains that cross the on-prem/cloud boundary (for example, an on-prem user synced to a cloud account that holds a privileged Entra role). Mapped to MITRE ATT&CK, the core activity is **T1069 – Permission Groups Discovery**, supported by T1087 (Account Discovery), T1482 (Domain Trust Discovery), and T1018 (Remote System Discovery).\n\n## When to Use\n\n- During an authorized internal penetration test or red-team engagement after obtaining any domain foothold or Entra credentials\n- When you need to prioritize escalation routes from owned principals to Tier-0 assets (Domain Admins, Global Administrator)\n- When assessing hybrid identity risk where on-prem AD is synced to Entra ID\n- During purple-team exercises to validate that detections fire on collection and on path-execution steps\n- When producing attack-path evidence and remediation guidance for a defensive client\n\n## Prerequisites\n\n- Authorized scope covering AD/Entra reconnaissance\n- A foothold: any valid domain user (for SharpHound) and/or valid Entra credentials or a token (for AzureHound)\n- Docker + Docker Compose on the analysis workstation\n- The collectors:\n  ```bash\n  # Deploy BloodHound CE (pulls Postgres, Neo4j, and the BloodHound API)\n  curl -L https://ghst.ly/getbhce -o docker-compose.yml\n  docker compose pull\n  docker compose up -d\n  # Reveal the randomly generated initial admin password\n  docker compose logs bloodhound | grep -i \"Initial Password\"\n\n  # AzureHound (download the release binary for your OS from the GitHub releases page)\n  #   https://github.com/SpecterOps/AzureHound/releases\n  chmod +x ./azurehound\n\n  # SharpHound CE collector: download SharpHound.zip from the BloodHound CE\n  # web UI (Administration -> Download Collectors), transfer to a domain-joined host.\n  ```\n\n## Objectives\n\n- Deploy BloodHound CE and authenticate to the web UI and API\n- Collect AD data with SharpHound and Entra data with AzureHound\n- Ingest both datasets and mark compromised principals as Owned\n- Run built-in analysis (Shortest Path to Domain Admins, Kerberoastable accounts, ADCS abuse)\n- Author custom Cypher queries for bespoke and hybrid attack paths\n- Prioritize and document escalation routes for the engagement report\n\n## MITRE ATT&CK Mapping\n\n| ID | Technique | Application in this skill |\n|----|-----------|---------------------------|\n| T1069 | Permission Groups Discovery | Enumerating AD/Entra group memberships and the permissions between principals to build the attack graph |\n| T1087 | Account Discovery | SharpHound/AzureHound enumeration of users, computers, and service principals |\n| T1482 | Domain Trust Discovery | Collecting and analyzing domain/forest trust relationships as graph edges |\n| T1018 | Remote System Discovery | Enumerating domain computers and their relationships (sessions, local admin) |\n\n## Workflow\n\n### Step 1: Deploy BloodHound CE and log in\nBring up the stack, retrieve the generated password, and reset it on first login.\n\n```bash\ndocker compose up -d\ndocker compose logs bloodhound 2>&1 | grep -i \"Initial Password\"\n# Browse to http://localhost:8080  (default user: admin)\n```\n\n### Step 2: Collect on-prem AD data with SharpHound\nOn a domain-joined Windows host (or via `runas`/token of a domain user), run the CE collector. `-c All` gathers every collection method; `--outputdirectory` controls where the ZIP lands.\n\n```powershell\n# Full collection\n.\\SharpHound.exe -c All --outputdirectory C:\\Temp\n\n# Stealthier LDAP-only collection (no host touch for sessions/local-admin)\n.\\SharpHound.exe -c DCOnly --outputdirectory C:\\Temp\n\n# Looped session collection to map logged-on Tier-0 users over time\n.\\SharpHound.exe -c Session --loop --loopduration 02:00:00 --outputdirectory C:\\Temp\n```\n\nFrom Linux, the Python collector (`bloodhound-ce-python`) is an alternative when you only have credentials and network access:\n\n```bash\npip install bloodhound-ce\nbloodhound-ce-python -u 'jdoe' -p 'Passw0rd!' -d corp.local -ns 10.0.0.10 -c All --zip\n```\n\n### Step 3: Collect Entra ID / Azure data with AzureHound\nRun AzureHound `list` with credentials, a JWT, or a refresh token, writing a single JSON file.\n\n```bash\n# Username/password (where allowed by CA/MFA policy)\n./azurehound list -u \"user@corp.com\" -p \"$PASSWORD\" -t \"corp.com\" -o entra.json\n\n# Using a previously acquired JWT (e.g., from roadtx / device-code phishing)\n./azurehound list --jwt \"$JWT\" -o entra.json\n\n# Using a refresh token\n./azurehound list --refresh-token \"$REFRESH_TOKEN\" -t \"<tenant-id>\" -o entra.json\n```\n\n### Step 4: Ingest data into BloodHound CE\nUpload the SharpHound ZIP and the AzureHound JSON through **Administration -> File Ingest**, or POST to the API.\n\n```bash\n# API ingest (after obtaining a JWT from /api/v2/login)\nTOKEN=$(curl -s http://localhost:8080/api/v2/login \\\n  -H 'Content-Type: application/json' \\\n  -d '{\"login_method\":\"secret\",\"username\":\"admin\",\"secret\":\"<password>\"}' \\\n  | python -c \"import sys,json;print(json.load(sys.stdin)['data']['session_token'])\")\n\n# Start a file-upload job, then PUT the collector ZIP/JSON to it\nJOB=$(curl -s -X POST http://localhost:8080/api/v2/file-upload/start \\\n  -H \"Authorization: Bearer $TOKEN\" | python -c \"import sys,json;print(json.load(sys.stdin)['data']['id'])\")\ncurl -s -X PUT \"http://localhost:8080/api/v2/file-upload/$JOB\" \\\n  -H \"Authorization: Bearer $TOKEN\" -H 'Content-Type: application/zip' \\\n  --data-binary @C:/Temp/BloodHound.zip\ncurl -s -X POST \"http://localhost:8080/api/v2/file-upload/$JOB/end\" \\\n  -H \"Authorization: Bearer $TOKEN\"\n```\n\n### Step 5: Mark owned principals\nIn the UI, search for each compromised account/computer, open the node, and toggle **Mark as Owned**. Owned principals seed pathfinding queries (`{owned:true}`).\n\n### Step 6: Run built-in analysis queries\nOpen the **Cypher** tab or use the pre-built queries in the search panel:\n\n- Shortest Path to Domain Admins\n- Kerberoastable accounts with a path to high value\n- AS-REP roastable users\n- Principals with DCSync rights\n- ADCS misconfigurations (ESC1-ESC8 edges in CE)\n- Computers with unconstrained delegation\n\n### Step 7: Author custom Cypher for bespoke paths\nUse Cypher for paths the built-ins do not cover, including hybrid AD-to-Entra chains.\n\n```cypher\n// Shortest path from any owned principal to Domain Admins\nMATCH p=shortestPath((n {owned:true})-[*1..]->(g:Group))\nWHERE g.objectid ENDS WITH \"-512\"\nRETURN p\n\n// Kerberoastable users (SPN set) with a path to Domain Admins\nMATCH (u:User {hasspn:true})\nMATCH p=shortestPath((u)-[*1..]->(g:Group))\nWHERE g.objectid ENDS WITH \"-512\"\nRETURN p\n\n// Principals who can DCSync the domain\nMATCH (n)-[:MemberOf*0..]->()-[:DCSync|GetChanges|GetChangesAll*1..]->(d:Domain)\nRETURN n.name, d.name\n\n// ACL abuse from owned principals (GenericAll/WriteDacl/WriteOwner/ForceChangePassword)\nMATCH p=(n {owned:true})-[:GenericAll|GenericWrite|WriteDacl|WriteOwner|ForceChangePassword*1..]->(t)\nRETURN p\n\n// Hybrid: on-prem user synced to an Entra account holding a privileged directory role\nMATCH p=(u:User)-[:SyncedToEntraUser]->(:AZUser)-[:AZHasRole|AZGlobalAdmin*1..]->(r)\nRETURN p\n```\n\n### Step 8: Prioritize and document\nRank paths by hop count, stealth (avoid noisy edges like HasSession requiring host touch), and tooling availability. Record each path with the principals, edges, required actions, and a remediation note (e.g., remove the abusable ACL, tier the account).\n\n## Tools and Resources\n\n| Tool | Purpose | Source
