HoneyLabs

UDP traffic

Datagrams matching country:DK 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.

Your plan searches up to 7d, so 30d was shortened. Plans

Amplification checks

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

ServicePortDatagramsSourcesFactor
Memcached11211/udp1110,000 to 51,000

The factor is how many bytes a reachable server can send back for each byte it receives, as published by CISA in alert TA14-017A.
