So let us assume that my computer was under attack caused by my careless click.
But what about PC room (피씨방) act? There were several people who had connections with them (seat number 32 and 41, and another one I can't remember), so at first they started with posting nasty things on Reddit. Like cat, turtle, etc. So I ignored it and called the police with the help of the worker there. Since I kept an vigilant eyes on those people, I guess they couldn't report it back to the hackers that I called the police. So hackers kept doing it, and moreover, they did some remote control thing, even though I didn't click anything, and I didn't open any email there. It was crazy, the monitor was shaking violently and things were typed by itself. How was this possible?
