Updated | Bloodbornepkg

# 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.

Note: Timed on a 2020 MacBook Pro (2.3 GHz i7) connecting to a remote DC over VPN. If you have automation scripts that rely on the old bloodhound.py output format, you have two paths forward. Quick Fix: Convert JSONL back to legacy JSON If you cannot update your parser immediately, use jq to reconstruct the legacy format:

| Metric | v0.7.2 (Legacy) | v1.0.0 (Updated) | Improvement | | ----------------------- | --------------- | ---------------- | ----------- | | Time to enum (LDAP) | 14m 22s | 8m 01s | | | Memory peak (RSS) | 1.2 GB | 340 MB | 72% less | | JSON to JSONL conversion| N/A (monolithic)| 2.1 GB/sec write | Streaming | | Session collection | 38% timeout | 2% timeout | 95% reliability | 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.

"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. Legacy default was NTLM, but now it is unset for security

# Concatenate all JSONL lines into a single array cat *.jsonl | jq -s '.' > legacy_computers.json Use the BloodHound v4.3+ collector CLI:

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. Quick Fix: Convert JSONL back to legacy JSON

After updating, always test with --help to review new flags like --disable-jsonl (reverts to old format) and --session-timeout (adjusts the new async session collector).
