It was written by a graduate student at Cornell University, Robert Tappan Morris, and launched on November 2, 1988, from the computer systems of the Massachusetts Institute of Technology.

It resulted in the arrest of Robert Morris which was featured as the first felony conviction in the US under the 1986 Computer Fraud and Abuse Act.

Although according to its creator, the Worm was not written to cause damage, but to gauge the size of the Internet.
