We've been getting frequent occurrences of PRTG Probe.exe sending out DNS lookups for sites Cisco Umbrella flags as malicious. For example it's looked up mail.kb8zgl.net and hourmediagroup.com within the past 24 hours. Both of these requests were blocked by Cisco Umbrella.
Could anyone shed some light on why this could be happening? I don't see how this behavior is tied to any sensor.
