The Making of Malware

It's a fitting title for computer viruses to be named after their real-world counterparts. For the most part, viruses on computers have similar intentions and infiltrate by similarly obtuse means. By definition viruses infect programs and partitions, but arenít designed to spread across networks. That privilege belongs to worms.

The primary goal of a worm is to proliferate, and although capable of carrying malicious payloads and behaving very much like viruses, this isnít necessarily the case Ė legend has it that the first worm ever written was by a team at Xeroc PARC in 1978 that was made to find idle processors on a network and dole out tasks, all in the name of aiding efficiency. And the Welchia worm, in 2003, went around downloading the latest security updates from Microsoft on the machines it infected, in the process plugging the same hole it exploited to enter the system.

Today, worms are largely malicious in nature and use a variety of mechanisms to infiltrate computers and spread across networks, especially the Internet. To make matters worse they often act as trojans, spyware, and mass-mailers for spam, making the damage they can do as diverse as the worms themselves. The Making of Malware - Feature - Tech Talk -
