“Hackers on Thursday replaced the English-language Web site for Arab satellite television network Al-Jazeera with a U.S. flag and the message ‘Let Freedom Ring.’ The hackers, calling themselves the “Freedom Cyber Force Militia,” briefly hijacked Internet traffic destined for Al-Jazeera’s Web site and redirected it to a different Web page on computers operated by Networld Connections Inc., an Internet provider in Salt Lake City. The likely hacking technique, called ‘DNS poisoning,’ fools so-called domain name servers across the Internet and is relatively difficult to defend against. Internet records show the Web directories sending traffic to Al-Jazeera’s site were changed early Thursday, apparently without authorization.”
