Which of the following characterizes a Worm in cybersecurity?

• A. Requires user action to spread
• B. Replicates itself without user intervention
• C. Encrypts files on the victim's machine
• D. Primarily attacks web servers

Answer: (B)

A worm in cybersecurity is defined by its ability to replicate itself independently without requiring any user action. This self-replicating behavior allows worms to spread across networks and systems swiftly and effectively, exploiting vulnerabilities without relying on users to inadvertently transmit it, such as through email attachments or downloads. This characteristic distinguishes worms from other types of malware, like viruses, which typically require some form of user interaction to propagate. By executing and replicating autonomously, worms can quickly affect a large number of systems, making them particularly dangerous and disruptive. Understanding this fundamental property of worms is essential for cybersecurity professionals, as it informs strategies for prevention, detection, and mitigation of such threats.
