kerberos_scan_internal

Explanation

This NDM is designed to detect scanning for Kerberos that is exiting the customer's network. Kerberos is a protocol for authenticating requests between hosts on a network. Outbound Kerberos scanning may be indicative of an infection and an attacker using a compromised machine on the customer network to pivot further outside of the network.

What to Look For

Scans launched from 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. This event could false positive in a situation where Netography has not been configured with the appropriate internal network IP address ranges.
