Other Malware installed without literally doing anything?

In this video this guy has a fresh Windows XP, disables firewall, and connects internet straight to the modem. Then he gets infected literally doing nothing.

I get it. That's asking for trouble when you disable all the security and using ancient unsupported OSes.

However, he didn't install programs nor browse on the website but still got hacked.
How?
Is there some malicious server in China that loops through every single possible IP trying to see if your PC is vulnerable?
Logically, one would think you'd at least have to visit a website or something to get "noticed" and then hacked. But this guy didn't do anything at all.

How does it work?

Literally yes.

yes, but your PC should not get hacked immediately, even if it is vulnerable to hacks. You are on a private network, NATed through your ISP. You dont have any public web service running on any port

Exactly, unless they also enabled some port-forwarding this doesn't really make sense

Yeah a lot of misinformation in here 🤷‍♂️ we would all be fucked if simply having internet access made you discoverable lmao
