Japan's Good Virus In Growing Cyber Arms Race

The Japanese Defense Ministry is developing a computer virus aimed at seeking and destroying cyber attacks launched against the country, according to local media reports.

The malware-fighting cyberweapon, which is being created by defense contractor Fujitsu for an estimated $2.3 million, has the ability to identify the source of a cyber attack with a high level of accuracy, then replicate itself from computer to computer, cleaning up viruses across the network.

The cyberweapon, which has been in development since 2008, has been tested in a closed network environment and was developed for defense.
