Computer worm

1. First developed by John Shoch and Jon Hupp at Xerox PARC (Palo Alto Research Center) in 1978, a worm is a destructive self-replicating program containing code capable of gaining access to computers or networks. Once in the computer or network, the worm causes harm by deleting, modifying, distributing, or otherwise manipulating data.


A worm may sometimes be called a worm virus.

Who created the first computer worm?

Robert T. Morris later developed the Morris Worm in 1988, which became the first Internet worm.

What's the difference between a worm and a virus?

A worm self-replicates and executes without any initial interaction from a user, whereas a virus requires a user to perform an action (e.g., opening an infected file or installing a program).

Can a worm be destructive?

Yes. Like a virus, a worm can be designed to be destructive and may even be designed to look for a specific target.
