A computer worm is a type of malware that is inserted into a device covertly and spreads copies of itself from device to device. A worm can clone itself without any human activity and interaction, and it does not need to attach itself to a software program in order to cause damage.

malicious software onto a computer. Sometimes the purpose of a computer worm is only to make copies of itself over and over — drain system resources, such as hard drive space or bandwidth, by overloading a shared network. In addition to inflict damage on computer resources, worms can also steal data, install a backdoor, and allow a hacker to gain control over a computer and its system settings.
In July 2010, after many frequent incidents in Iran two security researchers discovered the first computer worm used as a cyber weapon. Researchers labeled it “Stuxnet”, this worm emerged to be much more complex than the worms researchers were used to counter. This attracted the attention of high-profile security specialists around the world. Their immense research led them to culminate that the worm was being used to attack an Iranian power plant, with the utmost goal of destroying nuclear weapon production. Although the attack ultimately failed, this computer worm is still active on the threat aspect today.
