The former CEO and co-founder of YouSendIt, a popular file transfer service, was indicted this week on four counts of mail fraud. Khalid Shaikh, who left the Campbell, Calif.-based company in November 2006, was charged with using the ApacheBench tool to launch four separate denial-of-service attacks, between December 2008 and June 2009, against YouSendIt's servers, disabling the service for customers. Each count of mail fraud carries a maximum five-year prison term, three years of supervised release and a fine of $250,000. -- DK
