Morris Worm Hits Internet: Cybersecurity Crisis Begins

Robert Tappan Morris, a 23-year-old Cornell University graduate student, released a self-replicating program into the early internet on November 2, 1988. He intended it as a harmless experiment to measure the network's size. A programming error caused the worm to replicate far faster than intended, overwhelming roughly 6,000 computers, about 10% of the internet at the time. Systems at MIT, Berkeley, Stanford, and NASA were knocked offline. Damages were estimated at $100,000 to $10 million. Morris became the first person convicted under the Computer Fraud and Abuse Act, receiving three years' probation, 400 hours of community service, and a $10,050 fine. The incident led to the creation of CERT (Computer Emergency Response Team) at Carnegie Mellon, the first organization dedicated to internet security incident response.
