ToS Violation - Malicious Activity

Hello I am looking for some help, we have been given an error from linode with not alot of info. Can someone please help me workout what this is? from all I can tell it's just a port scan so nothing to worry about.

This is on a cpanel Server

port-scan <our ip=""></our>

From the looks of it, your Linode was scanning the ports of another compute instance on which was unauthorized, or was unexpected.

While there are legitimate reasons for port scanning, and other types of traffic and use cases can cause false flags, frequently port scanning is done for the purpose of malicious activity (gaining unauthorized access to a compute instance).

Tickets that Linode opens up on accounts like this usually are accompanied by instructions on next steps, but a pretty exhaustive list of next steps can be found in older Community Site posts such as this one:

Hopefully that helps!
