UDP traffic

Datagrams matching asn:46844 sent to HoneyLabs sensors over UDP in the last 7 days. DNS questions and QUIC client fingerprints are decoded on the sensor. Other datagrams are kept as their first bytes and labelled by protocol where it can be recognised.

A UDP source address can be forged, so each address listed here either sent the traffic or was impersonated by whoever did. UDP traffic is kept out of verdicts, feeds, watchlists and alerts.

Amplification checks

Probes for services that answer a small request with a much larger reply, the property reflection attacks rely on.

ServicePortDatagramsSourcesFactor
SNMPv2161/udp876.3
