TOKYO — Honda Motor Co. said Wednesday it had temporarily suspended production at a domestic factory due to a ransomware cyberattack employing the same type of computer virus that struck companies around the world last month.
The automaker found out last Sunday that the production control system at the plant in the city of Sayama, north of Tokyo, was infected by the malware that encrypts computer files and makes them inaccessible until the user pays a ransom. Output at the factory was halted Monday but restored the following day, the company said.
The Sayama factory produces about 1,000 vehicles a day, it added.
Honda Motor has also confirmed infection by the malware at its factories abroad, but it did not affect overseas production, the automaker said.
In May, the massive cyberattack struck at least 150 countries, with Nissan Motor Co.’s plant in Sunderland, Britain, halting production following the attack.
In Japan, Hitachi Ltd.’s computer systems were disrupted by the ransomware cyberattack, and one computer at East Japan Railway Co.’s local bureau was infected with the virus, but train operations were unaffected.
