bloodhound.py -d lab.local -u user -p pass --kerberoast --asrep This dumps crackable hashes directly into the output/ directory as roastable.txt alongside the JSONL files. The -s (session collection) flag was notoriously unstable in prior versions, often causing LDAP timeouts. The update replaces the synchronous LDAP paging with an asynchronous generator, reducing the chances of SIZELIMIT_EXCEEDED errors on domains with thousands of active sessions. D. BloodHound Enterprise (BHE) Compatibility The output schema now includes optional fields required by BloodHound Enterprise (e.g., OwnedObjects and HighValue flags). While backward compatible with the open-source Community Edition, this update prepares the collector for enterprise-tier attack path analysis. 3. Installation and Upgrade Guide If you are running an older version, you are likely missing critical bug fixes regarding TLS certificate validation and Python 3.11+ compatibility. Fresh Installation # Create a virtual environment (recommended) python3 -m venv bloodhound-env source bloodhound-env/bin/activate Install from PyPI pip install bloodhound Updating Existing Installation # Check current version bloodhound.py --version Upgrade pip install --upgrade bloodhound Verify update pip show bloodhound
# Instead of drag-and-drop, use: bloodhound-cli ingest /path/to/*.jsonl # New way to read bloodhound output import json with open('20231025_computers.jsonl', 'r') as f: for line in f: computer_obj = json.loads(line) if computer_obj['Properties'].get('AdminCount') == 1: print(f"High value: computer_obj['Properties']['name']") 7. Common Pitfalls and Solutions Problem: "The tool says 'No authentication method specified' even with -u and -p." Solution: The update requires explicit authentication flags. Use --auth-method (e.g., --auth-method NTLM or --auth-method Kerberos ). Legacy default was NTLM, but now it is unset for security. bloodbornepkg updated
If you are mid-engagement with a legacy BloodHound GUI (version 4.2 or older), . If you are using BloodHound CE 4.3+ or BHE, update immediately for the performance gains. bloodhound
bloodhound.py -d CORP.LOCAL -u Administrator -p 'P@ssw0rd' --disable-jsonl -ns 10.10.10.1 The bloodbornepkg update is the most significant evolution of the Python BloodHound collector since its inception. By embracing JSONL, asynchronous LDAP, and native roasting, it bridges the gap between rapid Python prototyping and production-scale C# tooling. By embracing JSONL
"JSONL files won't load into BloodHound CE v4.2 or older." Solution: Update BloodHound to v4.3+ OR use the conversion script above. BloodHound Community Edition v4.2 does not support JSONL. 8. The Road Ahead: What This Update Signals The bloodbornepkg update is not merely a maintenance release; it signals a philosophical shift toward streaming data pipelines and enterprise readiness . SpecterOps has moved BloodHound to a SaaS model (BloodHound Enterprise), but the open-source collector ecosystem is adapting.
"Unexpected keyword argument 'encrypt'" when connecting to DC. Solution: You are hitting an Impacket deprecation. Downgrade Impacket to 0.9.24 OR edit bloodhound.py line 247 to change encrypt to kerberos . (Better: open an issue on GitHub—this is a known regression.)
