On Christmas Day in 1994 Kevin Mitnick (and I believe a colleague?) launched a novel attack against Tsutomu Shimomura's computers that involved packet spoofing.

Among them were:
Here are some
One of the most interesting results from the research was that I found one-time-password devices (which were becoming popular because of password sniffers) for login over Telnet were easy to bypass by injecting data into an already authenticated connection. I could also display content (like a "go away" message) to be displayed on the user's screen. Ah, fun times.
