Is there a legitimate reason for a USB-ethernet hardware device to have been connected to my laptop?

There was an unknown network adapter in my device manager. I found out it was for a USB-RJ45 ethernet device, which I have never even seen before. This device was not present when I bought the machine. As far as I have researched, it is not installed by any software or devices I use.

I’m concerned because there is a known vulnerability in Windows that’s exploited using these devices. A malicious person with access to the device could have stolen my credentials and logged in. (Google Usb-ethernet windows vulnerability if you don’t believe me.)

I believe the police or another malicious party exploited that vulnerability, and they used it to install a keylogger and acquire my hardware info. Is the presence of this device suspicious enough, from an information security standpoint, to support my belief? What would you do if you discovered the same on an enterprise machine?

Possible visual problem on HP laptop screen

I own an HP Laptop. It’s system model is something like 15-bs2xx and its model number is 3TT16UA#ABA (I believe these are the things that typically need to be known, I’m not a computer wiz at all). I don’t know if my eyes are just being hypersensitive or not, but I feel like my screen has this weird "stippling" effect, little dots of a slightly different color appear across certain colors like a dark gray, orange, or yellow. When I watch videos, there’s always weird spaces of dotty pixels as well, especially around illumination in a dark room. Is this how the computer screen is supposed to look or is there something wrong with my graphics?

Company asking admin rights of my personal laptop [migrated]

What threats Android pose to anonymity when internet is accessed by a laptop through USB tethering but over Tor?

I use USB tethering on an Android 10 mobile to access internet on my laptop. I use Tor browser (TB) on laptop and keep my OS (a Linux distro) on laptop patched for security vulnerabilities. At times I need to consume certain content from websites which I don’t want any intermediary to know about.

Can my mobile device see what data I am requesting and receiving other than that I am connected to a Tor entry node and passing data to it back and forth?

Here’s what I have in mind:

  1. I enter security.stackexchange.com in TB’s URL bar in laptop
  2. TB establishes a secure connection and sends my request to Tor network.
  3. My telecom provider, the first potentially hostile intermediary I usually think of can see only that I am connected to Tor network. For scope reduction of this question, let us become ignorant and assume that my ISP or any intermediary further down does not have the capability to either see my original request or link it back to me.

So far, reasonably good. But, the first intermediary seems to be the Android 10 device itself. How can I be sure that my Android 10 device cannot know what data I am requesting and receiving other than that I am connected to Tor?

I am concerned because my mobile device is potentially hostile in my eyes. I do not know the capabilities of the baseband OS (which some state sponsored entities may exploit), don’t know the vulnerabilities of my Android 10 device which has vanilla Android fused with proprietary code. My mobile device is also at the mercy of its OEM which may not provide security updates for it in future.
