International hackers' collective Anonymous are poised for a massive cyber attack on North Korea to mark the 60th anniversary of the outbreak of the Korean War. The "hacktivists" threatened in April to attack 46 North Korean websites including the official KCNA news agency at 12 noon on Tuesday.
Anonymous in similar previous attacks temporarily paralyzed websites and retrieved data from them.
In a recent video clip on YouTube, they claimed to have extracted missile blueprints from the intranet of the North Korean military and other information.
Last Friday, KCNA denounced the hackers as a "ragtag band" under the control of U.S. and South Korean intelligence agencies. It claimed the intranet which Anonymous claim to have infiltrated "does not even exist."
