Chatting to the Islamic Republic News Service (IRNA), Brigadier General Gholam Reza Jalali effectively said that Siemens sabotaged its own machines.
He said that the German computer maker needed to explain why it provided “the enemies” with the information about the codes of the SCADA software and prepared the ground for a cyber attack against Iran.
Siemens has not made a comment on Jalali’s claims, but he is well placed within the Iran establishment to comment.
Jalali heads Iran’s Passive Defense Organisation which is a military unit responsible for constructing and defending the country’s nuclear enrichment facilities. He was the former commander in Iran’s Revolutionary Guard.
Jalali said that Iran would sue Siemens in the International courts. He said that the attacking countries should be held legally responsible for the cyberattack.
He claimed that Iranian boffins had traced the attack to Israel and the US, and the worm sent reports of infected systems to computers in Texas.
We are not sure if Iranian researchers had uncovered much about the attacks. Jalali probably got his information from the New York Times which said that Siemens cooperated in 2008 with the Idaho National Laboratory (INL) to help experts there identify vulnerabilities in the SCADA hardware and software sold by the German firm.
However Jalali insisted that Stuxnet did not cause major damage or disrupt its nuclear enrichment program because researchers discovered the worm and instituted defences.
Insecurity outfit Symantec disagrees. It said that the first attacks in June 2009 infected Iranian computers just 12 hours after the worm was compiled.
