This was pre-linux for me but something you can still do in most distros so I think it’s a valid story.
In 1999 I was using Napster on computer running MS-DOS. I was 12 years old and an aspiring open media enthusiast/stupid script kiddie. I was using the file explorer interface in Napster and accidentally gave access to my entire C drive. I also had opened ports to share certain media and to fuck with my friends using daemon tools (back then you could do stupid stuff like control a friend’s desktop with certain versions of daemon tools). Immediately I started receiving packages called things like “sleep.tight.tiny.mite” and I knew I was fucked so I clicked in the Napster interface and clicked “delete” and deleted my entire active drive.
I panicked and installed the only operating system we had which was a random copy of Red Hat. When my dad came home I pretended like it had always had Linux on it. I do think he was more impressed than mad.
