Worm

A worm is a self-replicating malware program that spreads across computer networks without requiring user intervention. Unlike viruses, worms do not need a host file or program to attach themselves to. Once a worm infects a system, it can replicate itself and spread to other vulnerable systems using network connections. Worms can cause significant damage by consuming network bandwidth, exploiting vulnerabilities, or carrying out malicious actions on the infected systems.
