Back in the day there was this monstrosity known as "Windows 95." Microsoft was advertising the hell out of it. The PC manufacturers were advertising the hell out of it and their PCs. Internet in dorms was becoming a big thing. There were ads all over TV telling luddite parents that their kids had to have a Windows 95 PC to go off to college or they would FAIL!
Well, predictably, people did this in droves. They then went to their dorms (or did it at home) and hooked their non-firewalled Windows 95 machines up to the Internet with full file and print sharing turned on. It used to be a sport to go surfing through SMB shares on these college networks. You'd find peoples' email, their entire documents folder, and yes, porn they shot of their girlfriends and God knows what else. One time I knew that this dude had a hidden camera in his dorm and his girlfriend wasn't aware of it. So in the interest of being anti-revenge, I went into his email, found her email address, and forged an email from him to her with a link to it. I'm sure that went over well.
There were also so many bugs in the Windows TCP/IP stack, such as it was. Winsock was still even a thing. Then there was Winnuke, where you could send a malformed TCP/IP packet to an IP address and blue screen someone's computer. Anybody who had any clue blocked it in short order, but you always had the script kiddies and trolls and otherwise annoying shits who would pop into IRC or something else and it was necessary to just eliminate them in short order. Most of them never figured it out. ("Uh, every time I say something stupid my computer crashes. What a coincidence!")
This was before Napster and all the rest. In fact, originally it was kind of the original peer-to-peer file sharing. I used to have a huge library of MP3s and stuff from back in the day but that was lost long ago in a HDD crash. Not that I really miss any of it.
