Robert Tappan Morris, also known as rtm, (born November 8, 1965), is an associate professor at Massachusetts Institute of Technology, in the Institute's department of Electrical Engineering and Computer Science.cite web |date=2007 |url = http://www.csail.mit.edu/biographies/PI/bioprint.php?PeopleID=301|title = Robert Morris|format = HTML |publisher = csail| accessdate = 2008-08-23 | last= |quote=] He is best known for creating the Morris Worm in 1988, considered the first computer worm on the Internet.cite web |date=2007 |url = http://groups.csail.mit.edu/mac/classes/6.805/articles/morris-worm.html|title = The Robert Morris Internet Worm|format = HTML |publisher = mit| accessdate = 2008-08-23 | last=Brendan P.

The worm

Morris created the worm while he was a graduate student at Cornell University. The original intent, according to him, was to gauge the size of the Internet. He released the worm from the Massachusetts Institute of Technology (MIT) to conceal the fact that it actually originated from Cornell. The worm was designed to count how many machines were connected to the internet. Unknown to Morris, the worm had a design flaw. The worm was programmed to check each computer it found to determine if the infection was already present. However, Morris believed that some administrators might try to defeat his worm by instructing the computer to report a false positive. To compensate for this possibility, Morris directed the worm to copy itself anyway, fourteen percent of the time, no matter the response to the infection-status interrogation. This level of replication proved excessive and the worm spread rapidly, infecting several thousand computers. It was estimated that the cost of repair for the damage caused by the worm at each system ranged from $200 to more than $53,000. The worm exploited several vulnerabilities to gain entry to targeted systems, including:
* a hole in the debug mode of the Unix "sendmail" program,
* a buffer overrun hole in the "fingerd" network service,
* the transitive trust enabled by people setting up rexec/"rsh" network logins without password requirements.

RTM was viewed as a hero in some circles because he exposed a major security flaw in the UNIX system. He served no jail time, and was only sentenced to community service and probation.

Morris is a longtime friend of Paul Graham. Graham dedicated his book "ANSI Common Lisp" to him, and named the programming language that generates the online stores' web pages RTML in his honor. Graham also lists Morris as one of his personal heroes saying "he's never wrong."
