HoneyLabs

UDP traffic

Datagrams matching asn:209630 sent to HoneyLabs sensors over UDP in the last 24 hours. 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.

Requests a service answers without a handshake. Scanners send them to find open DNS, NTP, SNMP or SSDP servers, which are also the servers reflection attacks abuse.

Amplification checks

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

ServicePortDatagramsSourcesFactor
SNMPv2161/udp1216.3
CLDAP389/udp8156 to 70
SSDP1900/udp8130.8
WS-Discovery3702/udp8110 to 500
Portmap111/udp417 to 28

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.
