There are no doubt several other download locations. This binary has a detection rate of 3/56. The various reports indicate that it phones home to a server at:
18.104.22.168 (Impsat, Argentina)
I strongly recommend that you block traffic to that IP. Payload is likely to be the Dridex banking trojan.
A contact sent some more download locations (thank you!)
..and also some additional C2s..
22.214.171.124 (NoTag Community / Hetzner, Germany)
126.96.36.199 (1&1, Germany)
