The Japanese government has been quietly developing a cyberweapon since 2008, which reportedly is able to track, identify and disable sources of online attacks, according to The Daily Yomiuri.
The virus which was developed by Fujitsu for the Japanese government has the ability to trace cyberattack sources beyond the immediate source to all "springboard" computers used in the transmission of the virus "to a high degree of accuracy" for distributed denial-of-service (DDoS) attacks, the report noted. It can also disable the attack and collect relevant information.
Commenting on the project, Motohiro Tsuchiya, professor at Keio University and a member of a government panel on information security policy, said Japan should increase "anti-cyberattack weapons development" by reconsidering the weapon's legal definition since other countries have launched similar projects. But Graham Cluley, senior technology consultant at Sophos, doesn't think it's a good idea. He says a malware cyberweapon uses resources such as disk space, memory and CPU time, which might lead to unexpected side effects.
