Computer Worm

Unlike viruses that need you to click something, worms spread by themselves across networks. They find vulnerable computers and infect them automatically, then use those to infect more. One worm can spread to millions of computers in hours without anyone clicking anything.

What is Computer Worm?

A self-replicating malware program that spreads across networks without requiring user interaction, exploiting vulnerabilities to infect other systems automatically.

Understanding worm is essential for building a strong security posture. This knowledge helps organizations identify threats early and respond appropriately.
