Speaking to TOI from Bangalore on Monday, Isro officials, requesting anonymity, said that the worm only strikes a satellite’s programme logic controller (PLC). “We can confirm that Insat-4 B doesn’t have a PLC. So the chances of the Stuxnet worm attacking it appear remote. In PLC’s place, Insat-4 B had its own indigenously-designed software which controlled the logic of the spacecraft,’’ said a source. PLC’s main function is to control the entire “logic of the spacecraft’’. Other space experts described PLC as a digital computer used for automation of electro-mechanical processes. Sources, however, said Isro is awaiting Jeffrey Carr’s presentation at Abu Dhabi next to know the full details of the Stuxnet internet worm. Carr in a blog published in Forbes recently suggested that the resumes of two former engineers at Isro’s Liquid Propulsion Systems Centre (LPSC) at Mahendra Giri in Tamil Nadu said that the Siemens S7-400 PLC was used in Insat-4 B, which can activate the Stuxnet worm.
