United States v. Morris was an appeal of the conviction of Robert Tappan Morris for creating and releasing the Morris worm, one of the first Internet-based worms. This case resulted in the first conviction under the Computer Fraud and Abuse Act. In the process, the dispute clarified much of the language used in the law, which had been heavily revised in a number of updates passed in the years after its initial drafting. Also clarified was the concept of "unauthorized access," which is central in the United States' computer security laws.^[1] The decision was the first by a U.S. court to refer to "the Internet",^[2] which it described simply as "a national computer network."^[1]
