Hey All,

Just posting to see if anyone has seen any strange outbound traffic on port 3389 from Microsoft Windows Server over 
the last few hours.

We witnessed an alarming amount of completely independent Microsoft Windows Servers,  each on separate vlan and 
subnets (ie all /30 and /29 allocations) with separate gateways on and completely separate customers, but all 
services were within the same 1.x.x.x/16 allocation all simultaneously send around 2mbit or so data to a specific 
target IP address.


Have you contacted Microsoft yet?
https://support.microsoft.com/oas/default.aspx?gprid=1163&st=1&wfxredirect=1&sd=gn

If you have a support contract (which you probably do) you'll get a
very quick response if you choose the "security" option.

Whatever you do, do let everyone know what the problem turns out to be.
