The Japanese government confirmed this Tuesday (1st) that a cyberattack is responsible for the problems registered by a local supplier of Toyota, which forced the automaker to stop production for a day in the country.
Government spokesman Hirokazu Matsuno confirmed the attack on parts supplier Kojima Industries but said the case was still under investigation and did not reveal further details.
It also warned that “the risk of cyberattacks grows due to the current situation, including Ukraine”, and urged companies to “strengthen cybersecurity measures”.
On Monday, the Japanese press reported that the Kojima Industries group suffered a ransomware attack. The company indicated that it had detected a “threat message” on Saturday night, before discovering that a server was “infected with a virus”.
The message had to be published by Toyota because Kojima’s server was still offline.
The company does not know when it will be able to restore the system and resume production.
Toyota said on Monday that, due to the problem, it would have to suspend production at all 28 lines at its 14 Japanese plants on Tuesday.
The company intends to resume operations on Wednesday (2).
