The world has grown wearily accustomed to the concept of cyberspace being mankind’s newest battleground. So while the Japanese defence establishment was understandably unsettled by the recent cyber attacks against arms company Mitsubishi Heavy Industries (MHI)—which first occurred in August but were only disclosed this week—the phenomenon will have struck governments and corporations that have experienced similar attacks as nothing particularly new.
The specifics of the attack on MHI and other Japanese entities remain unclear. While the Japanese media has attempted to trace the attack back to China—the usual suspect in these cases—its origin has not been publicly confirmed. Certainly, Beijing denied that it was involved, as it always does, despite admitting earlier this year to the existence of a PLA cyber warfare unit known as the Blue Army.
