UDP traffic

Datagrams matching asn:11320 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
SNMPv2	161/udp	9	1	6.3
Portmap	111/udp	4	1	7 to 28
DNS	53/udp	4	1	28 to 54
CLDAP	389/udp	4	1	56 to 70
SSDP	1900/udp	4	1	30.8
Memcached	11211/udp	4	1	10,000 to 51,000
NTP	123/udp	3	1	556.9

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.
