Ubuntu proxy settings changed itself to all_proxy=socks://127.0.0.1:8888 while reading about socks on Mikrotik website

You need to improve your reading comprehension or be more honest. I did not blame Mikrotik. Don’t make false accusations. Also, the proxy settings were changed at the system level, not the browser.

Check if your PC is compromised

I don’t know how, but thanks for the tip I guess.

The possibility that the Mikrotik website or their device could be compromised is not something out of science fiction. Insinuating otherwise and trying to shame me for reporting this incident makes you look foolish at best and malicious at worst.

I would agree that I have encountered quite a bit of weird bugs lately but does that make ME weird? Again, some questionable people would say yes.
