First computer usage by John Brunner in his 1975 book The Shockwave Rider.
worm - Computer Definition
A type of malware that replicates itself across a computer network by making copies of itself, which it sends to other computers. A worm embeds itself in memory and may replicate itself so many times that it causes the host to crash. Note that a worm is neither a Trojan horse nor a virus. See also malware, spyware, Trojan horse, and virus.
A worm is a self-replicating, self-contained software program that does not need to be part of another program to propagate. A virus, in contrast, attaches itself to and becomes part of another executable program. Worms as well as viruses typically contain some kind of malicious payload besides the propagation and infection mechanism.
On February 3, 2005, Sophos, Inc., a company providing virus detection and other security tools, warned that a version of the Bobax-H worm, hidden within Saddam Hussein photos showing him deceased, invaded computers and carried message warnings such as “Saddam Hussein: Attempted Escape. Shot Dead.” Other versions of the worm had pictures of an allegedly captured Osama Bin Laden. If activated, the payload had the same effect as the Sasser worm.
Security experts worldwide have been exploring various ways of stopping worms in their tracks. In April 2005, Professor Shigang Chen and Professor Sanjay Ranka at the University of Florida said they designed an Internet worm early-warning system to detect the initial sign of a malware attack. Professors Chen and Ranka said that their suggested early-warning system monitors a “used” address space and relies on RESET packets to find the scan sources. Their research paper focuses on TCP-focused worms and details a means of avoiding so-called “false positives” by viewing reply traffic from targets instead of monitoring the SYN packets to track half-open connections.

(1) A destructive program that replicates itself throughout a single computer or across a network, both wired and wireless. It can do damage by sheer reproduction, consuming internal disk and memory resources within a single computer or by exhausting network bandwidth. It can also deposit a Trojan that turns a computer into a zombie for spam and other malicious purposes. Very often, the terms "worm" and "virus" are used synonymously; however, worm implies an automatic method for reproducing itself in other computers. See virus, logic bomb, smartphone virus, Stuxnet, Worm.ExploreZip virus and Morris worm.
(2) A program that moves through a network and deposits information at each node for diagnostic purposes or causes idle computers to share some of the processing workload. See ethical worm.
(3) (WORM) (Write Once Read Many) An optical disc that can be recorded only once. Updating requires destroying the existing data (all 0s made 1s), and writing new data to an unused part of the disk. There are two kinds of WORM technologies. Ablative large-format (12-14") WORM is the traditional type, which makes a permanent change in the optical material. Continuous composite write (CCW) WORM is a mode in multifunction 5.25" optical (MO) drives that emulates a WORM drive. The data are not permanently changed, but the drive contains firmware that ensures that recorded areas are not rewritten. See optical disc and MDISC.
