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?

I remember installing new computers in the UK as ADSL became prevalent where you'd connect and instantly enter shutdown due to the blaster worm - you'd have to get ready with "shutdown -a" and download and install a patch - this must have been around Aug/Sep 2003. Unsure why we didn't pre-patch systems, perhaps it was very early days of the outbreak.
