Here are the signatures for versions 17-19. Signature for v17 (XML-RPC) Look for POST /xmlrpc.php requests with system.multicall occurring between 1 AM and 4 AM. The IPs will appear in Tor exit node lists (check Daniel Palau’s Tor Exit Node List ). Signature for v18 (JWT) Look for GET /api/auth/jwt with missing Referer headers. Tor exits rarely send Referer . Signature for v19 (AI User-Agent) This is the hardest. v19 uses valid browser UAs but inconsistent TLS fingerprints. Use JA3 fingerprints. A FU10 v19 crawler will have a JA3 hash of e7d705a...
