On October 4, 2005, 19-year-old Samy Kamkar wanted to pull a practical joke on his new MySpace page to get a laugh out of his friends. Unbeknownst to him, he accidentally created a computer virus (JS.Spacehero), and in less than 24 hours, over one million users on MySpace would be infected with it. Not too long after, the computer worm shut the website down entirely. Did Samy just take brief control of the world's most popular social media? By using only his mouse and his keyboard?
