Urgent: Need more Information for blacklisted URL

Hello together,

i am working as a security-engineer in my company. We discovered suspicious DNS Queries to the URL: *****.***.madkingos.mooo.com. The Target is not available anymore (DNS Response = NXDOMAIN)

The only "public" URL Reputation-Scanner which clarified the URL as malicous is http://url.fortinet.net/rate/

The fortinet url scanner categorized the URL as malicious / malware.

Can anyone provide more information why the url has been blacklisted. (which malware has been found) this would be very useful to clean up the systems.

Thanks in Advance
