Not even close to a security expert, but I'd suggest you should get on
wireshark or use a packet-reading ability in netflow (never used it)
and try to analyze the packets its sending. You may come across what's
going on. How often is the connection happening? The highly-raised
download rate is a bit worrying, along with how it's hitting all these
odd ports. I hope it's nothing too bad.
