A worm is a type of self-replicating malware that spreads across computers or networks without needing to be attached to a host file (unlike viruses). Worms typically exploit vulnerabilities in software or operating systems to propagate, and they often operate without any user intervention. The primary goal of a worm is to spread as quickly as possible, often causing damage to systems or networks in the process. Learn more: https://en.wikipedia.org/wiki/Worms
