A worm is a self-replicating malware that propagates independently across networks, exploiting vulnerabilities to spread without user action. Worms are particularly dangerous because they do not require a host file or human interaction to spread. They consume network bandwidth and system resources, potentially causing systems to crash. Famous examples include the ILOVEYOU and WannaCry worms, which caused global damage. Worms often carry payloads, such as ransomware or spyware, amplifying their impact. Preventive measures include patching software vulnerabilities and using robust firewalls. Why Other Options Are Incorrect: 1. Virus: Requires a host file and user action, such as opening an infected file, to spread. 2. Trojan: Disguised as legitimate software and requires execution by the user. 3. Spyware: Focuses on stealthily collecting user data rather than replication. 4. Ransomware: Encrypts user data and demands payment but does not replicate itself. The autonomous nature of worms makes them a critical concern in network security.
