So I ran shields up last night and ran the port scan feature for Bit Defender Box 2 (https://www.grc.com/x/ne.dll?bh0bkyd2)
What I found curious is it failed on multiple ports. The most aggregious of which is Port 135, which is commonly used by DCOM servers on windows machines. I had NO Windows machines running. Everything else on the network when I ran the test was (embedded) Linux based. (Android devices, network printers, Rokus, Access Points)
I'm running from my cable modem->BitDefender Box 2 -> internal network
So why is the Bit Defender box 2 responding to this on the outside world? This is kind of a dangerous port to have hanging out there as it can remotely activate services on Windows Machines.
