This image is used for the task pods, not the agent pod.

This is where we saw the malicious activity

During the task pod runtime

What malicious activity?

The task pod (experiment) started reaching out to an IP associated with malicious activity. The IP was associated with 1000+ domain names. The activity was identified in AWS guard duty with a high severity level.

The domain names were bogus sounding businesses

Would using 22.04 Ubuntu still work in the task execution?

For task execution? It would work, yes, however it would take longer to install, I assume

BoredHedgehog47 What is the pod container itself ?
EDIT:
Are you suggesting the default "ubuntu:18.04" is somehow contaminated ?

Yes

This is an official Ubuntu container (nothing to do with ClearML), this is Very Very odd...
