He decided to test it by releasing it into the wild - the Internet. The program ran amok: it had a bug which meant it replicated far faster than Morris had expected. Many machines crashed, at sites including universities, military organisations, and medical research facilities. The estimated cost of dealing with the worm ranged from $200 to more than $53,000.
Programmers worked non-stop to get a temporary fix to slow down the worm's spread. A team at Berkeley University found a solution after about 12 hours; another was worked out at Purdue University. Many sites disconnected from the network, hampering the distribution of solutions.
Morris was later named in the New York Times as the author and subsequently convicted of violating the Computer Fraud and Abuse Act (Title 18), and sentenced to three years of probation, 400 hours of community service, a fine of $10,050, and costs of his supervision. His appeal was rejected.Reuse content
