Thank you smax. That was nice of you to try and help me. I definitely appreciate it very much! I understand what you mean about the encryption, but the hackers seem to find a way to keep a step ahead. I don't have a wireless keyboard, and I don't plan on getting one either.
I just found this article below. I'm just gonna get a wired one, and not worry about it. Odds are I would be fine, but I don't know how long it would stay that way. There was a lot more concerning stuff than just that paragraph.
<<<none of the mouses it tested encrypted their clicks. Also, while most of the keyboards the company tested do encrypt their data before sending it to the dongle, the dongles didn’t always require that the data be encrypted. Both of these things would make it possible for a hacker to fool the dongle on a victim’s computer into thinking that his remote clicks and keystrokes are legitimate.>>>
And from the same article is this paragraph noting that Logitech released a patch fixing that problem as I mentioned in the previous post:
In a statement, Logitech’s senior director of engineering, Asif Ahsan, said the company came up with a software update to fix the problem. However, the vulnerability Bastille detected “would be complex to replicate” since it requires being physically close to the victim, he said, which makes it “a difficult and unlikely path of attack.”
And in that same article there are other things that indicate that manufacturers are taking the issue seriously.
Not trying to convince you to go wireless. If wired works for you, then stick with it. More pointing out that MouseJack is likely not much an issue anymore as once it was discovered, companies addressed the issue. Is it possible that there are other unknown security issues with wireless mice/keyboards? Sure. But, then there are likely tons of unknown security issues with lots of things out there...that is why they are unknown.
So, personally, I am not going to worry about someone trying to remotely control my mouse. I did pick the mouse necessarily because it is wireless. I picked it because I liked the feel and the number of buttons that I could map to things I wanted the mouse to do. And I could not find an equivalent wired mouse at the time with the same number of buttons (other than MMO mice, but I did not want a "keypad" of buttons on the side of the mouse like what MMO mice have). It would have been fine if the mouse was wired, but I find I like not having the wire.
Of course, if I decided to go with a trackball, then wireless seems pointless to me. Trackballs by their very nature don't need to move, so a wire is less of an issue. A mouse that moves is better in my experience without a wire getting in the way. But, the only reason to worry about a wire with a trackball is basically aesthetic reasons...and I don't care about that (I use a wired keyboard, so I have wires on my desktop anyway).
