Editing Melissa (computer virus) (section)

== Description ==
The virus was released on March 26, 1999, by David L. Smith.<ref>{{cite web|title = Justice mysteriously delayed for 'Melissa' author |last=Poulson|website=[[The Register]] |url=https://www.theregister.co.uk/2001/08/01/justice_mysteriously_delayed_for_melissa/}}</ref>
Smith used a hijacked [[AOL]] account to post the virus onto an Internet newsgroup called "alt.sex."<ref>{{Cite web |title=Melissa Virus |url=https://www.fbi.gov/history/famous-cases/melissa-virus |access-date=2022-04-01 |website=Federal Bureau of Investigation |language=en-us}}</ref> It soon ended up on similar sex groups and pornographic sites before spreading to corporate networks. However, the virus itself was credited to ''Kwyjibo'', a [[macro virus]] writer for ''VicodinS'' and ''ALT-F11'', by comparing [[Microsoft Word]] documents with the same [[globally unique identifier]]. This method was also used to trace the virus back to Smith.

The "list.doc" file contains a [[VBScript|Visual Basic script]] that copies the infected file into a template file used by Word for custom settings and default [[Macros in Microsoft Word|macros]]. If the recipient opens the attachment, the infected file will be read to computer storage. The virus then creates an Outlook object, reads the first 50 names in each Outlook Global Address Book, and sends a copy of itself to the addresses read.<ref>{{Cite web |title=What is the Melissa Virus? |url=https://www.techtarget.com/searchsecurity/definition/Melissa-virus |access-date=2022-04-06 |website=SearchSecurity |language=en}}</ref> Melissa works on Microsoft Word 97, Microsoft Word 2000 and Microsoft Outlook 97 or 98 email clients. Microsoft Outlook is not needed to receive the virus in email, but it is unable to spread via other emails without it.

A second payload occurred when the current minute matches the day when it is being launched, where the quote "Twenty-two points, plus triple-word-score, plus 50 points for using all my letters. Game's over. I'm outta here." is inserted into open Microsoft Word documents. This and the Kwyjibo alias are references to an episode of ''[[The Simpsons]]'', "[[Bart the Genius]]".<ref name="bbc-guilty">{{cite web |title = Melissa virus creator pleads guilty |publisher = BBC |date = 1999-12-09 |url = http://news.bbc.co.uk/2/hi/science/nature/557605.stm}}</ref>
