>One of my favorite low key social engineering hacks is that I used to have a keylogger installed on every machine I own. Whenever a friend needs to hop on my machine to show me something, they'd log into an account they own and I would have their password.
This isn't a "low key social engineering hack", it's betraying someone's trust.
>I would sit next to them and subtly jerk the mouse pointer right before they were about to click on something and it drove them mad for a good 20 minutes before I couldn't hold onto the giggles anymore.
This isn't actually funny, it's just being obnoxious and mean.
If you're next to them why not just jerk their arm when they are trying to click? It achieves the same "goal" of "entertaining" yourself and pissing the other person off. Jerk their laptop when you walk by. Throw stuff at them. Smack them in the head. Trip them when they get up to pee. "Hilarious."
>among a group of friends where everyone was trying to hack everyone else and pretty much anything was considered fair game.
This sounds like the bully saying "we were all having fun together."
You don't know the difference between having fun with someone and having fun at their expense - and that's just disturbing.
As someone who lived during the Windows 98 era, I wouldn't want others reading my IMs and emails (I had some very sexual and personal communication over those channels) or viewing my browsing habits.
