What did the Anna Kournikova virus use to spread itself?

Answer 1

The Anna Kournikova Virus was a worm that spread by email, disguised as an email attachment with the filed name "AnnaKournikova.jpg.vbs." The virus was a Visual Basic script that, once opened, emailed itself to all the contacts within the user's Outlook address book. Anna Kournikova was a payload-free virus, however, and did not erase any files or send information back to the creator. (http://www.techopedia.com)

Answer 2

The Anna Kournikova virus spread itself through email attachments disguised as a picture of the Russian tennis player Anna Kournikova. When opened, the attachment would release the virus onto the recipient's computer, allowing it to infect and spread to other systems.
