Advanced Threat Protection research

I am having trouble determining what is happening here.  I see the source is google dns, the destination is my internal dns server. the threat is clickmatters.biz.  How do I track this down to find out what is going on.  I checked web logs to see if anyone went to this site, nothing found.  It all happened around 2:25am while the office was closed. Thanks for any direction.

    Is caching the DNS traffic

    200.5 is my DNS

    200.20 is the endpoint

    That dst_ip is your infected PC, so either your DNS is infected, or an endpoint has made that query to your DNS

  • Thank you! I'm pretty certain an endpoint made a DNS query.  All the logs show port 53 and the "source" is google DNS and a couple others.  I was able to reproduce it and it showed my username and ip address as source.  The problem is, I am in the middle of a domain migration and have 2 trusted domains. The firewall is only syncing with one.  This will be a challenge.
