Which statement defines a Worm?

Which statement defines a Worm?

• A. A program that copies itself repeatedly
• B. A Virus
• C. A Cloud Storage
• D. A Firewall

Answer: (A)

At the heart of this concept is self-replication and network spreading. A worm is defined by its ability to copy itself and move from one computer to another without needing a user to run it. It can scan networks, exploit vulnerabilities, and propagate autonomously, often causing widespread infection quickly. This differs from a virus, which typically needs to attach to a legitimate program or file and requires some user action to run the infected code. Cloud storage is just a data storage service in the cloud, not malware. A firewall is a security tool designed to block unauthorized access, not to replicate or spread. Therefore, the statement describing a program that copies itself repeatedly best captures what a worm is.
