America and Israel had the help of three other countries, including the Netherlands and Germany, in this operation; It is believed that the other country was France.

But according to Yahoo News, the Dutch intelligence agency played a major role in the implementation of this work.
According to the claim of this report, an Iranian engineer is provided by the Dutch intelligence agency known as AIVD with all the important tools for installing Stuxnet and also provides access codes and spoofing devices to America and Israel.

Siemens control systems in Natanz were not connected to the Internet, so the attackers had to find a way to infect them.
The Holland’s guy either directly installed Stuxnet in these systems with the help of flash memory, or infected the system of one of the engineers there, who then unknowingly entered Siemens systems.

On the other hand, Spiegel weekly in an article raised the possibility that this virus was unintentionally transferred to the computers of the Bushehr nuclear power plant by the experts of the Russian Atomstroyexport Company and by means of a flash memory.
However, according to Tabnak news agency, an Iranian spy and a member of the People's Mojahedin Organization had introduced a flash drive carrying the virus into Iran's equipment.

The Stuxnet virus, as an industrial spyware, sent the internal information of Siemens production and research centers systems installed in Iran to a server abroad.

A study on the spread of Stuxnet by Symantec found that the main affected countries in the early days of the virus were Iran, Indonesia, and India, and even the United States and France were not spared.

A few months after the discovery of Stuxnet, an Israeli website said that Iran may have arrested and executed several Natanz workers on the suspicion that they helped infect the devices with Stuxnet.
Two intelligence sources who spoke to Yahoo News said the Stuxnet program had human casualties, but did not say whether Holland’s agent was among them.
