The Experiment That Escaped: The 1988 Morris Worm

The nineteen eighty-eight internet consisted of only sixty thousand machines built on a foundation of mutual trust.

A one-in-seven reinfection rule caused the software to replicate exponentially and crash systems nationwide.

The worm exploited a debugging back door in sendmail and buffer overflow vulnerabilities in the fingerd service.

Administrators were forced to physically pull network cables out of walls to stop the digital infection.

Robert Tappan Morris received the first conviction under the nineteen eighty-six Computer Fraud and Abuse Act.

The incident led to the creation of the first formal digital emergency response organization at Carnegie Mellon.
