The term “computer worm” was first used in 1975 in the novel “The Shockwave Rider” by John Brunner. In this novel, the protagonist of the story creates a worm that collects data. In the early days of computer science, worms were designed to exploit a system’s vulnerabilities. Instead of seriously damaging the infected computers, they just kept multiplying in the background. Today, however, the purpose of computer worms has changed. Today, attackers often use them to gain full access to their victims’ computers.Ĭomputers connected to a network are susceptible to various forms of malware, including computer worms. A computer worm is malware that reproduces itself and spreads over network connections. The computer worm does not usually infect computer files, but rather infects another computer on the network. This is done by the worm replicating itself. The worm passes this ability on to its replica, which allows it to infect other systems in the same way. The difference between computer worms and viruses can also be found here. Computer worms are stand-alone programs that replicate themselves and run in the background, while viruses require a host file to infect.
