Early Worms such as the Melissa Worm, Sobig, and MyDoom were all distributed by email attachments, and they were all executed by the recipient of that email attachment. worms were placed in email attachments, and when the user reads them, they begin to spread themselves across the system

After infecting many computers using file-sharing software, the MyDoom worm demonstrated its capacity to spread quickly, which is extremely dangerous. Computer worms also have the capacity to destroy and change files, which is a potentially fatal characteristic.

When worms infiltrate a computer system, they have the ability to change and destroy data, as well as put other malicious software on the system. Every computer worm has a distinct goal; some are designed to duplicate themselves, while others are designed to consume system resources.

Aside from that, they may also be used to establish a backdoor on a computer, steal data, and give hackers the power to manage the machine’s operating system and configuration settings

Is there a difference between worms and viruses?

Computer worms and viruses are not the same things, yet they both have the same goal: to cause damage to a person’s computer system. Viruses are computer programs that are meant to cause damage to a victim’s computer by corrupting or deleting the data stored on the system.

Worms, on the other hand, are created with the intent of reproducing and spreading. The primary goal of these individuals is to alter data and the computer system. On the other hand, widespread worm reproduction can cause a significant amount of damage to a whole network of systems.

When it comes to execution, viruses require the involvement of humans. Actions such as downloading an infected file after being tricked by a malicious email are examples of cybercrime. Following a virus download and the usage of suspicious software, viruses can infiltrate a computer system.

Worms, on the other hand, do not require human intervention. After getting access to your computer system, malware will begin duplicating itself and spreading to as many devices in the vicinity of your computer as possible.
