Iran Fights Malware Attacking Computers

By DAVID E. SANGER

WASHINGTON — The Iranian government agency that runs the country’s nuclear facilities, including those the West suspects are part of a weapons program, has reported that its engineers are trying to protect their facilities from a sophisticated computer worm that has infected industrial plants across Iran.

The agency, the Atomic Energy Organization, did not specify whether the worm had already infected any of its nuclear facilities, including Natanz, the underground enrichment site that for several years has been a main target of American and Israeli covert programs.

But the announcement raised suspicions, and new questions, about the origins and target of the worm, Stuxnet, which computer experts say is a far cry from common computer malware that has affected the Internet for years. A worm is a self-replicating malware computer program. A virus is malware that infects its target by attaching itself to programs or documents.

Stuxnet, which was first publicly identified several months ago, is aimed solely at industrial equipment made by Siemens that controls oil pipelines, electric utilities, nuclear facilities and other large industrial sites. While it is not clear that Iran was the main target — the infection has also been reported in Indonesia, Pakistan, India and elsewhere — a disproportionate number of computers inside Iran appear to have been struck, according to reports by computer security monitors.
