Intruders design most worms to replicate and spread across a network, thus consuming available computing resources and, in turn, causing network servers, web servers, and individual computer systems to become overloaded and stop responding. However, some worms also carry a payload to damage the host system. Worms are a subtype of viruses. A worm does not require a host to replicate; however, in some cases, the worm’s host machine is also infected. Initially, black hat professionals treated worms as a mainframe problem. Later, with the introduction of the Internet, they mainly focused on and targeted Windows OS using the same worms by sharing them in via e-mail, IRC, and other network functions.

Some of the latest computer worms are as follows: = Monero = Bondat. Beapy Module 01 Page 68 Certified Cybersecurity Technician Copyright © by EG-Council All Rights Reserved.
