As "state of the art" viruses developed, a new breed came to the scene: worms. This charming name is used to describe a type of virus that not only infects the host machine, but ... replicates itself over the network. In practice that means that a well-written worm can create real mayhem around the world in a matter of days. It is estimated that damage from some famous worms reaches billions of dollars.

Whereas viruses must be physically transported from one host to another, a worm propagates itself, usually over a network. A worm may or may not have a destructive payload. The payload is independent of the worm itself which is designed to replicate and spread as quickly as possible, taking advantage of a widespread vulnerability.Worms areoften usedto carry a payload like a back door. The worm exploits a vulnerability to install the back door giving its author remote access to the target machine. The worm component then looks for additional vulnerable systems to take advantage of. Worms can bury a network by generating huge volumes of traffic.

The most famous of the security incidents in the last decade was the Internet Worm incident which began from a Unix system. But Unix systems were considered virus-immune -- not so. Several Linux viruses have been discovered. The Staog virus first appeared in 1996 and was written in assembly language by the VLAD virus writing group, the same group responsible for creating the first Windows 95 virus called Boza.
