Rajendrasinh Makwana: The financial crisis could've been worse
Remember what dire straights the U.S. mortgage market was in back in 2009? Now imagine if all of mortgage giant Fannie Mae's servers had been wiped out. Rajendrasinh Makwana was fired from his job as a sysadmin there, but didn't have his server privileges turned off until the end of the day -- leaving him time to hide a malicious script at the bottom of a legitimate script, set to erase huge amounts of data four months after his firing, leaving only a message that said "Server Graveyard." A sharp-eyed admin stumbled upon it by accident, averting disaster; Makwana was sentenced to 41 months in jail.
