Thanks, and you said it re: firewalls! FYI, below is how my firewall characterizes the "miscellaneous vulnerability" on my sonicTransporter that it is blocking from attacks. Also, since I removed ARC from all my devices yesterday, I have seen no attacks reported. Fingers crossed; I haven't gone over 24 hours in the past six months without at least one documented attack. Will report back my observations.

I don't actually use ARC, so will remove the app from my phone and see what happens.

@Miska, FWIW, one of the services running on my SonicTransporter is HQPlayer.

Nope; see below

Thanks. I get hundreds of these from different IP addresses. A typical pattern is that an address will try to access the network three or four times over a period of hours, then stop and not come back. But I haven't kept records. Netgear messages to me essentially have resulted in my having a lengthy a log of past hits, if anyone is interested in taking a look. (FYI, I got a few similar hits on another networked device, my dog's television, but I assume all anybody got from that was noting that my dog really likes NCAA volleyball and Olympic gymnastics.)

For a long time now, my Netgear Armor monitoring and protection service has been sending me, sometimes multiple times in a day, notifications of attempted unauthorized connections to my network via one of my audio devices (see a recent example below). To date, I have simply accepted the assurance of Netgear Armor that the attempted connections were blocked, and I also have seen no evidence of malfeasance on my other networked computers. But ... Does anyone have insight into the potential source, nature, purpose, and level of concern associated with these (blocked) intrusions? Should I be concerned?
