On Saturday, there is a strong possibility of Internet activities such as shopping and surfing coming to a halt as a hacking group has threatened to shut down the Net.

“Operation Global Blackout 2012 looks to shut down the Internet for a whole day tomorrow (Saturday) by disabling its core DNS servers, making websites inaccessible,” said Interpol’s Secretary-General, Ronald K. Noble.

Mr. Noble was speaking at the thirteenth D.P. Kohli memorial lecture on “Multijurisdictional Investigation: Operation Unmask” in New Delhi.

According to Mr. Noble, the hacking group, Anonymous, is protesting against several reasons including the crash of Wall Street and irresponsible leaders.
