UPDATE 10/4 6:47 EDT

I have been going through all the comments. THANKS!!!!!! I did not know about the techniques listed, so they are extremely helpful. Sorry for the slow update. As I mentioned below, I got behind with this yesterday so work cut into my evening.

I ran a port scan. The first syntax, -p, brought no joy. The nmap software itself suggested changing to -Pn. That brought an interesting response:

nmap -Pn 1-9999

Starting Nmap 7.93 ( https://nmap.org ) at 2024-10-04 11:44 BST Failed to resolve "1-9999". Nmap scan report for Host is up (0.070s latency). All 1000 scanned ports on 192.168.0.46 are in ignored states. Not shown: 990 filtered tcp ports (no-response), 10 filtered tcp ports (host-unreach)

Nmap done: 1 IP address (1 host up) scanned in 6.03 seconds

Just to be absolutely sure, I turned off my work computer (the only windows box on my network) and reran the same syntax with the same results.

As I read this, there is definitely something on my network running windows that is not showing up on the DHCP.

I have been using Logitech peripherals for years. Logitech gear always just worked.

Now they demand internet accounts to use the features of the keyboard and mouse that I purchased. WTF?

Not only that, have to use wide-open-to-snooping Chrome to adjust the settings. You cannot adjust/use your mouse and keyboard if you just use Firefox.

This only makes sense if they are planning (or are already) tracking my every move online to sell to advertisers or spooks.

What are the good options?

Also, if anybody sees how these changes could be benign, please let me know.

EDIT:

By popular demand:

The keyboard I bought that started this journey: MX Keys S

The key feature that first demanded cloud access: Swithing between computers, now it is requires it to adjust the receivers. I have both a Bolt and a Unifying receiver.

Mouse (actually a trackball) that now is requesting that I use a Chrome Browser to adjust it: M570

Software:
The Logi SetPoint Settings I open from Windows now requires you to log into your Logitech account to make changes to your Unifying or 2.4 ghz usb receiver. This link takes you to a screen that says Logi Web Connect. It does not work unless you use the latest version of Chrome, Edge, & Opera, but reccomends Chrome for the best experience.

Logitech + used to require this to enable options, but I don’t see it on my Windows computer anymore. It is still on my Mac, but upon opening it to confirm for this message, it seems to be announcing that it is now able to incorporate AI into everything I type. (ugggh)
