Twitter was hacked last night, directing users who tried to log on to a site sporting a green flag and the proclamation, “This site has been hacked by Iranian Cyber Army,” according to CNN. The website was reportedly down for nearly an hour. The company responded to the flap on its official Twitter feed, saying at about 2:30 a.m. ET on Friday, “Twitter’s DNS records were temporarily compromised but have now been fixed. We will update with more information soon.”
