Businesses around the world scrambled on Saturday to prepare for a renewed cyber attack, convinced that a lull in a computer offensive that has stopped vehicle factories, hospitals, schools and other organizations in around 100 countries was only temporary.
"Production was affected overnight but luckily there was no full production scheduled for this weekend, only some "stamping" operations," he said.
"Nearly all plants should be able to resume their activity tomorrow", the spokesman said on Sunday.
The attack had forced the company to stop production at sites in France, shortly after it announced that output had been halted for the same reason at a site in Slovenia. Lost production will be made up, but the initial financial impact has not been revealed, per the spokesman.
Renault is the first French company to confirm it has been affected by Friday's wave of cyberattacks, which apparently exploited a flaw exposed in documents leaked from the US National Security Agency. In turn, Renault and Nissan's system operations were questioned.
"If we give any information on our systems we would be sending a message to potential hackers", a PSA spokesman said.
But experts say the concentration of infections in emerging markets, with relatively low numbers in Europe and the United States, reflects the way they mainly affected older Windows computer systems.
British Home Secretary Amber Rudd said Saturday that 45 public health organizations were hit, but she stressed that no patient data had been stolen. The probe covers "Renault and other possible victims", the source said. All plants are back online, save for the Douai, France facility, which builds Renaults exclusively.
