DNS Response Policy Zone (RPZ) — Match

This site has been blocked

The domain you tried to reach was flagged as malicious by the DNSVault threat-detection framework and rewritten at the recursive resolver before your browser ever made the connection.

Attempted domain
Redirected to walled garden at blocked.dnsvault.io

Why was it blocked?

Supervised classifier

A meta-gated ensemble of Char-CNN+BiLSTM, SAE+Stacking, and RF+TF-IDF models identified the domain as DGA, Phishing, or Malware with high confidence.

Unsupervised anomaly score

Seven-dimensional analysis (entropy, structure, encoding, character ratios, co-occurrence, TTL variance, DNS records) produced an anomaly score above the operational threshold.

Hybrid fusion verdict

HybridC pipeline (Char-CNN encoder + Isolation Forest) confirmed the verdict with PR-AUC 0.913 — its decision was pushed to the BIND9 Response Policy Zone and the domain rewritten in real time.
