Design and infection The virus was made to be sent in an email with an attachment that carried the virus. When the attachment was opened, the virus would download itself to the computer. The virus can only affect Windows based computers. The virus came with a package that would spam the SCO Group website. SCO had caused arguments within the Linux community for getting copyrights in some open source software. However, only 25% of the infected computers would launch the attack. After the virus has been downloaded, it leaves the computer open to other malware by leaving a "backdoor" open.
History
The virus was found to be a threat on January 26, 2004. The virus quickly spread and proved a threat to the SCO group. To try and get the public to catch the maker of the virus, the SCO group offered $250,000 U.S. dollars as a reward for catching the creator. Another type of the virus, Mydoom.B was found on January 28. Because it was made to attack the Microsoft web site, Microsoft offered a $250,000 U.S. dollar reward if the maker of the virus was caught. This was the third time Microsoft offered a reward for catching a virus creator. On February 1, 2004, the virus downed the SCO group site with many denial-of-service attacks. On February 3 the virus attacked the Microsoft site and little damage was caused.
26 January 2004: The Mydoom virus is first identified around 8am EST (1300 UTC), just before the beginning of the workday in North America. The earliest messages originate from Russia. For a period of a few hours mid-day, the worm's rapid spread slows overall internet performance by approximately ten percent and average web page load times by approximately fifty percent. Computer security companies report that Mydoom is responsible for
