In cyber attack world, what are the differentiations between worm and virus ?

Question

Just curious about it. 😊😅😅 Can you guys explain it? Thank you 😁

Answer 1

Hello, Cevin Samuel
A virus is a self-propagating program: it spreads from file to file and from computer to computer. In addition, the virus can be programmed to destroy or damage data.

Worms are considered a subclass of viruses, but they have characteristic features. The worm multiplies (reproduces itself) without infecting other files. It is implemented once on a specific computer and seeks to spread further to other computers.

Answer 2

Worms are programs that replicate themselves from system to system without the use of a host file.

A virus is a small program written to alter the way a computer operates, without the permission or knowledge of the user.

Answer 3

My friend firstly good to know that you are interested in cyber security.

A worm and a virus both comes under the domain of malwares firstly.which also include Trojans as third branch.

A virus is a code which is specifically designed to perform some task ,but it is so designed that it always needs some resource to stick with , without any host/ resource it can not exist and work independently thats a very high level description of the term virus .
Now,

Worm is againn a code/program desighned to perform a task but is independent ,it dont needs a host / resource to stick on.

Also both viruses and worms do replicate ( if talking generally ) but virus will be replicated when its resource will , but worms replicate independently.

There is much more is this domain but I just gave you a high level overview.
