The Japanese Defense Ministry is in the process of developing a computer virus capable of tracking, identifying and disabling sources of cyber-attacks, The Yomiuri Shimbun has learned. The development of the virtual cyberweapon was launched in 2008. Since then, the weapon has been tested in a closed network environment.
Cyberweapons are said to already be in use in countries such as the United States and China. However, in Japan there is no provision on the use of cyberweapons against external parties in existing legislation on foreign attacks. With this in mind, the Defense Ministry and Foreign Ministry have begun legislative consideration regarding the matter, according to sources.
The most distinctive feature of the new virus is its ability to trace cyber-attack sources. It can identify not only the immediate source of attack, but also all "springboard" computers used to transmit the virus. The virus also has the ability to disable the attacking program and collect relevant information.
