UDP traffic

Datagrams matching asn:216014 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.

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.

Service	Port	Datagrams	Sources	Factor
Portmap	111/udp	30	1	7 to 28
mDNS	5353/udp	26	1	2 to 10
SNMPv2	161/udp	4	1	6.3
SSDP	1900/udp	4	1	30.8
TFTP	69/udp	3	1	60
RIPv1	520/udp	2	1	131.24

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.
