Yeah, when I was at boarding school (high school), we had a LAN in the dorms full of everybody's shiny new Windows 95 desktops. So everybody just had SMB shares, and nobody was careful about what they clicked on. I put a trojan exe with the icon made to look like a text file in mine. Someone clicked on it, and then I popped up a dialog box that said "Hello! You've got a trojan. Open notepad and let's talk about it" and he typed into notepad and I watched with the keyboard sniffer and answered back by injecting keypresses. (I couldn't see video of the screen - I think I could take screenshots, though) I learned a lot about networking that year.
