Cyber-attacks were launched against three major banks and three TV broadcasters in South Korea on March 20, and North Korea is suspected of being the perpetrator. There is also a report that the Chinese military is likely to be involved in many cyber-attacks against the United States.

Japanese government organizations and private companies were also targeted by cyber-attacks. For example, defense contractors such as Mitsubishi Heavy Industries Ltd., IHI Corp. and Kawasaki Heavy Industries Ltd. reported cyber-attacks against them in 2011.

It is imperative that the government and businesses develop a heightened awareness of the danger from cyber-attacks and cyber-espionage and take protective measures as needed.
