Wall Street Journal: French police have arrested a man known as "Hacker Croll" who allegedly hacked into Twitter accounts belonging to famous people, including President Obama and Britney Spears. He did not post anything to the accounts or attempt to profit financially, but he did take screen shots of the pages he accessed and posted them online.
How did he do it? Apparently, he just guessed the answers to the "secret" questions that Twitter asks users who forget their passwords. "The man in question had no training in computers," said French state prosecutor Jean-Yves Coquillat. "He was just very cunning."
