Reproduction is Strictly Prohibited Computer Worms Computer worms are standalone malicious programs that replicate, execute, and spread across network connections independently without human intervention. 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. Attackers use worm payloads to install backdoors on infected computers, which turns them into zombies and creates a botnet. Attackers use these botnets to initiate cyber-attacks. 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.
