Was This the First Denial of Service Attack?

An anonymous reader writes "Way back in 1974, Dave Dennis, then aged 13, decided to try out the -ext- TUTOR command on the PLATO system at the University of Illinois, and see if he could cause all the terminals of other users to go offline. It worked. And he never got caught. Of course, the powers that be eventually caught on and fixed the -ext- command so terminals by default didn't automatically receive -ext-'s sent from other locations."

    The first recorded denial of service was performed by a 13 year old, who was basically using a "script kiddie" technique? Well, color me surprised.

      He made it himself. He wouldn't trust anyone else to get the spelling right.

    Yeah, but this was 1974, when overly-trusting users used commands to do USEFUL things, rather than cause mischief (or shove adverts in front of you)!

    If you remember 1974, you weren't there, maaan!

    So I'm guessing you weren't around in 1974. It might also surprise you to learn that once upon a time there were no virus scanners or firewalls. I bet I just blew your mind with that one...
