What is Worm?

Not all kinds of malware seek to infect devices. A computer worm, for example, attempts to increase traffic to cause disruptions and performance problems, both on the computers it infects and on the network itself. To achieve this, it produces copies of itself and distributes them across the network in order to spread to as many devices as possible.

One of the greatest dangers of a computer worm is its autonomy. Once it has been installed on a computer, it can spread without any external action by the user. Some of them include a payload: code designed by the attacker that opens a backdoor in the computer and allows him to carry out malicious activities: controlling the system, stealing information… The latter are the most dangerous class of computer worms.
