A worm makes multiple copies of itself which then spread across the network or through an internet connection. These copies will infect any inadequately protected computers and servers that connect—via the network or internet—to the originally infected device.
How do most worms spread?
Worms can be transmitted via software vulnerabilities. Or computer worms could arrive as attachments in spam emails or instant messages (IMs). Once opened, these files could provide a link to a malicious website or automatically download the computer worm.
How does a worm work?
Worms get the job done by exploiting hidden vulnerabilities in your computer's operating system (OS). Hackers create worms in such a way that they can burrow into the target OS and do their dirty work without your knowledge.
Where does Worm virus come from?
To get a worm in a computer, the worm is often transmitted through vulnerabilities in software. They could also be sent through email attachments or within instant messages or spam emails.
What harm does a worm cause to the public?
Worms cause damage similar to viruses, exploiting holes in security software and potentially stealing sensitive information, corrupting files and installing a back door for remote access to the system, among other issues.
