The accusation was published yesterday by Kayhan. Accordingly, the Stuxnet virus targeted Iran's atomic programs, but they only attacked Siemens devices. Therefore, the German company must be responsible for that.
However, Siemens declined to comment on the allegations.
Recent surveys show that the origin of the Stuxnet virus originated in the US and the Jewish nation. Iran accuses Siemens of being responsible for the incident, because its control system often uses monitoring and data acquisition monitoring software (SCADA) and has been attacked by computer worms. This software has cleared the way for the Stuxnet virus.
The official also said that Siemens had to take responsibility and explain how and why it provided the enemy with information about SCADA software code and paved the way for attacks. aimed at Iran's nuclear plant.
Some foreign experts have described Stuxnet as an attack launcher led to target Iran's atomic program. This can pose a great risk if not detected.
In September, Iran also said that the computers at the Bushehr nuclear power plant located in Russia were attacked but not damaged. Bushehr - Iran's first nuclear power plant - was still not ready to operate and had to delay its start-up time but was also attacked by Stuxnet.
NATO ambassador to Russia said in January, the virus attacked the computer system at Bushehr. This could pose a risk of a nuclear disaster like the Chernobyl disaster in Ukraine in 1986.
Some defense analysts say the main goal is to target Iran's uranium enrichment process. This is the process to create fuel for nuclear power plants. Western countries have accused Iran of developing nuclear weapons but Tehran has denied this allegation.
