Through some odd Google rabbit hole, I ended up at what appeared to be the GitHub website. I reflexively tried logging in to view my repositories. Upon attempting to log in, it said my browser did something "odd", and the login failed.
I checked the browser URL and it had instead, at the top
https://hzb.world/. Fearing this was some sort of phishing expedition, I immediately went and changed my password on GitHub and set up 2FA.
https://hzb.world/ came up with literally nothing. What is going on here?
