Japan has fallen victim of a global "ransomware" cyberattack that has created chaos in 150 countries, with hundreds of computers hit at 600 locations.
Nissan Motor Co confirmed today some units had been targeted, but there was no major impact on its business. Hitachi spokeswoman Yuko Tainiuchi said emails were slow or not getting delivered, and files could not be opened.
The company believes the problems are related to the ransomware attack, although no ransom is being demanded. They were installing software to fix the problems.
The Japan Computer Emergency Response Team Coordination Center, a non-profit providing support for computer attacks, said 2,000 computers at 600 locations in Japan were reported affected so far.
A few individuals also reportedly were affected. The attack, known as "WannaCry," paralysed computers that run Britain's hospital network, Germany's national railway and other companies and government agencies worldwide in what may be the largest online extortion scheme ever.
