Strange security alert from Xfinity on my Flex6400m

Xfinity updated their security for my Gateway. When reading the information and looking at my account it had this listed. I run my 6400m with the front panel not windows smartsdr. I run strictly digital modes mostly FT8 and PSK31. I took this snapshot. Any thoughts?image

    I also use Xfinity Xfi for my home Internet and about once a week I see a blocked attacked notice similar to that. They show which device was attacked and it can be the PC my 6400 is connected to, the Maestro, my iPhone, iPad or Macbook. They seem pretty random but the Xfinity firewall does block them. The only remedy they show is to restart the device. My 6400 and Maestro are connected to a switch with an Ethernet connection to my router. I do use several of the Xfi wireless extenders in home but don't know if that's a factor. As long is Xfinity can block them I expect it's not a problem.

    I also use another program for my antivirus and firewall. Just thought it was odd that the Flex was the only one trying to be accessed.

    With a more advanced router (like a pfsense), or even just a linux based routing system running firewall system with logging, you will see these kind of attempts often.  Again, this like someone knocking on the outside of your locked and dead-bolted front door.  They know there is a house there and that there is a door, but it doesn't mean that they have access.

    In the same way, there are many bad actors out there on the internet searching for IP addresses that have systems on the other end they can try to exploit.  Knowing this, SmartLink was designed from the ground up with security in mind.  A rogue attempt like this will not be able to gain access to the radio.

    I don't know enough about your network to try to explain why your radio would be the only device that shows up in that list, but I'm sure there is a reasonable explanation.
