Anonymous hackers claim to have crashed Justice Department website

Anonymous, the group of activist hackers, claimed to have crashed the Justice Department website in retaliation for prosecutors shutting down the popular file-sharing site Megaupload.com. "The government takes down Megaupload? 15 minutes later Anonymous takes down government & record label sites," the group wrote on its Twitter account. Anonymous also claimed to have crashed the websites of Universal Music, the Motion Picture Association of America (MPAA) and the Recording Industry Association of America (RIAA), which are some of the most vocal proponents of tougher copyright enforcement laws.
