According to the report based on a top secret document of the U.S. National Security Agency and testimonies made by former government officials of the U.S., it has run the whole gamut of base espionage acts such as gathering information about nuclear development in the DPRK through its cyber attacks for several years.

Snowden, former agent of the CIA, at an interview with German media, disclosed that U.S. agents had illegal access to the computer network of the DPRK a few years ago and have regularly monitored it after setting up the hacking and tracking program CNE they obtained by hacking at the south Korean computer network.

This is clear evidence revealing once again the true colors of the U.S. as a cursed empire of hackers.

Whenever an opportunity presents itself, the U.S. made much fuss over heavy loss it suffered due to cyber attacks by other countries.

For example, the U.S. kicked off a racket for slapping "additional sanctions" against the DPRK after deliberately linking the cyber attack on the Sony Pictures Entertainment to the latter.

The U.S. advanced the theory on cyber warfare in the 1990s. Since then, it has organized lots of cyber warfare units, beefing up and developing them.

It has stepped up preparations for a cyber war, steadily increasing military expenditure for it under the pretext of "protecting national interests."

It set up the cyber command in May, 2010.

In October, 2012 Obama issued a secret presidential order regarding U.S. policy on cyber warfare operations, which was meant to enable the U.S. army to mount a sudden preemptive cyber attack upon any country by mobilizing all means.

Pursuant to the scenario, the U.S. Department of Defense is developing new type cyber weapons capable of jamming and disabling the military systems of other countries even under the conditions that the systems are not connected with the Internet if necessary.

At a secret presidential order, the U.S. agents mounted a cyber attack code-named "Olympic Games" upon a nuclear facility of Iran and seized the design for its interior operation. They secretly input the malignant virus "Stuxnet" to the inner network system of the Iranian nuclear facility, causing delay in its nuclear activities for peaceful purposes.

Such criminal acts of the U.S. are being openly perpetrated against not only those countries opposed to it but also its allies.

The U.S. has further intensified hacking and espionage operations in various parts of the world. This is aimed to gather data necessary for realizing its wild ambition for dominating the world as well as improve and test the methods and means to be used for the future cyber wars.

It is a serious challenge to the international community aspiring after world peace and stability that the U.S. is abusing the latest sci-tech successes for making a weapon for dominating the world.

The U.S. is, indeed, a country of war maniacs running riot to realize their wild ambition for hegemony by infringing upon the sovereignty of other countries and even violating and stamping out human civilization. It is also a chieftain of aggression and intervention and a plot-breeding base.

It is by no means fortuitous that the world public is censuring the U.S. acts of harassing the security of the cyber space.

It would be well advised to stop running riot, well aware that successes made in the latest information technology are by no means its monopoly.
