Document Summary

The first examples of malware were known as viruses. Michelangelo in 1992- little damage; lots of hype. A program that attaches itself to a file, reproduced and spreads from one file to another. Malicious programs that can destroy data files and damage your computer. Self replicating program that enters network through security holes. Unlike a virus, a worm does not need to attach to another program. Can hard a network, at minimum it consumes bandwidth. A program that appears to perform a legitimate function while actually doing something else, such as stealing a password. Presented as useful or harmless to induce the user to install and run. Dos: denial of service perpetrator uses a single internet connection to either exploit a software vulnerability or floor a target with fake requests. Distributed dos: comes from multiple pc"s, harder to trace, botnets. Launched from multiple connected devices that are distributed across the internet.
