msmq_tcp_scan_internal_internal

Explanation

This NDM is designed to detect scanning for Microsoft Message Queuing on TCP port 1801 inside a customer's network. Microsoft Message Queuing is a messaging protocol that allows applications running on different servers to communicate.

What to Look For

Unauthorized scanning activity launched inside your network may be an indication that your network is compromised. Investigate hosts that are the source of this sort of activity in order to make sure that it is authorized and expected, and the hosts have not been compromised. Authorized scanners should be labeled in Netography Fusion so that scanning events do not trigger for them.
