Code Curiosities

In 1988, a Cornell grad student meant to write a harmless program to map the internet. Instead, he created the first major internet worm that brought down 10% of all connected computers. We'll explore how Robert Tappan Morris accidentally became the internet's first cyber-criminal, why his dad tried to stop him, and how this digital disaster helped create the cybersecurity industry we know today.
