ATP Alert with 127.0.0.1 as source an destination to server.aeinow.com

Daniels_UTM

At a customer side i recieved the following alert:

messageid="18010" log_type="ATP" log_component="DNS" log_subtype="Drop" user="" protocol="UDP" src_port="47832" dst_port="53" src_ip="127.0.0.1" dst_ip="127.0.0.1" url="server.aeinow.com" threat="C2/Virut-A" event_id="2FEE641E-F51B-44E5-A46F-938ED5AA4352" type="Standard" host_login_user="" host_process_user="" endpoint_id="" execution_path=""

 

How can we identify the source of this packet?

    As it is 127.0.0.1, there could be some reason behind it. 

    One of the internal services asking for this Domain. In most cases, this is a Email Cluster or the customer created this domain in his setup as a FQDN Service. 

    Could you quickly look at the MTA to this time frame, if there is something? 
    Or does the customer has a FQDN Host created for this server?
