Did The Stuxnet Worm Kill Indiaâ€™s INSAT-4B Satellite? posted by JEFFREY CARR On July 7, 2010, a power glitch in the solar panels of Indiaâ€™s INSAT-4B satellite resulted in 12 of its 24 transponders shutting down. As a result, an estimated 70% of Indiaâ€™s Direct-To-Home (DTH) companiesâ€™ customers were without service. Indiaâ€™s DTH operators include Sun TV and state-run Doordarshan and data services of Tata VSNL. INSAT-4B was put into orbit in March, 2007 by the Indian Space Research Organization (ISRO), which conducts research and develops space technology for the government of India. It is also the agency which controls and monitors Indiaâ€™s satellites and space vehicles while they are operational. Once it became apparent that INSAT-4B was effectively dead, SunDirect ordered its servicemen to redirect customer satellite dishes to point to ASIASAT-5, a Chinese satellite owned and operated by Asia Satellite Telecommunications Co., Ltd (AsiaSat). AsiaSatâ€™s two primary shareholders are General Electric and China International Trust and Investment Co. (CITIC), a state-owned company. China and India are competing with each other to see who will be the first to land another astronaut on the Moon. China has announced a date of 2025 while India is claiming 2020. What does this have to do with the Stuxnet worm thatâ€™s infected thousands of systems, mostly in India and Iran? Indiaâ€™s Space Research Organization is a Siemens customer. According to the resumes of two former engineers who worked at the ISROâ€™s Liquid Propulsion Systems Centre, the Siemens software in use is Siemens S7-400 PLC and SIMATIC WinCC, both of which will activate the Stuxnet worm. I uncovered this information as part of my background research for a paper that Iâ€™m presenting at the Black Hat Abu Dhabi conference in November. My objective for that presentation will be to provide an analytic model for determining attribution in cases like Stuxnet. My objective for this post is simply to show that there are more and better theories to explain Stuxnetâ€™s motivation than just Israel and Iran, as others have posited. My personal research wonâ€™t be available until after Black Hat Abu Dhabi, however I hope others will pick up this thread, give it a good yank, and see what unravels before then.
