A powerful computer code attacking industrial facilities around the world, but mainly in Iran, probably was created by experts working for a country or a well-funded private group, according to an analysis by a leading computer security company.
The malicious code, called Stuxnet, was designed to go after several “high-value targets,” said Liam O Murchu, manager of security response operations at Symantec Corp. But both O Murchu and U.S. government experts say there’s no proof it was developed to target nuclear plants in Iran, despite recent speculation from some researchers.
The malware has infected as many as 45,000 computer systems around the world. Siemens AG, the company that designed the system targeted by the worm, said it has infected 15 of the industrial control plants it was apparently intended to infiltrate. It’s not clear what sites were infected, but they could include water filtration, oil delivery, electrical and nuclear plants. None of those infections has adversely affected the industrial systems, according to Siemens.
US officials said last month that the Stuxnet was the first malicious computer code specifically created to take over systems that control the inner workings of industrial plants. A number of governments with sophisticated computer skills would have the ability to create such a code. They include China, Russia, Israel, Britain, Germany and the United States. But O Murchu said no clues have been found within the code to point to a country of origin.
