HoneyLabs

UDP traffic

Datagrams matching asn:10439 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

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.

Peer-to-peer

3 datagrams from 3 sources

File-sharing clients trying to reach a peer that used one of these addresses before. This is not scanning, so it is left out of every other figure on this page.

Amplification checks

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