Iran alleges Siemens should be held responsible for Stuxnet attack

Siemens is being accused by Gholamreza Jalali, head of Iran's civilian defense, for helping the United States and Israel to launch a cyber attack on its nuclear facilities according to Kayhan daily report.

Jalali made a statement that German engineering company who provided Iran its control systems used to operate complicated factory machinery known as Supervisory Control and Data Acquisition (SCADA) was partially responsible for that the Stuxnet was successful.

"The investigations show the source of the Stuxnet virus originated in America and the Zionist regime," Jalali was quoted as saying.

Jalali said Iran should hold Siemens responsible for the fact that its control systems used to operate complicated factory machinery -- known as Supervisory Control and Data Acquisition (SCADA) -- had been hit by the worm.

"Our executive officials should legally follow up the case of Siemens SCADA software which prepared the ground for the Stuxnet virus," he said.

"The Siemens company must be held accountable and explain how and why it provided the enemies with the information about the codes of SCADA software and paved the way for a cyber attack against us," he said.
