Cyberattack worm used on Iran called a "Digital Warhead"


The Stuxnet cyber attack on Iran began with the use of a flash drive like the one above. 
The extent of the damage to the Iranian nuke program is unknown. 


Worm Can Deal Double Blow to Iran's Nuclear Program -John Markoff

German software engineer Ralph Langner, who in September was the first to report that the Stuxnet computer worm was apparently designed to sabotage targets in Iran, said that the program contained two separate "digital warheads," designed to disable both Iranian centrifuges used to enrich uranium and steam turbines at the Bushehr nuclear power plant.

He described two different attack modules that are designed to run on different industrial controllers made by Siemens. "It appears that warhead one and warhead two were deployed in combination as an all-out cyberstrike against the Iranian nuclear program," he wrote.

Iran's Nuclear Program Reportedly Struggling - Glenn Kessler

Iran's nuclear program has experienced serious problems, including unexplained fluctuations in the performance of the thousands of centrifuges enriching uranium, leading to a temporary shutdown. Speculation immediately centered on the Stuxnet worm, a computer virus that some researchers say was designed to target Iran's centrifuge machines so that they spin out of control.

Report Suggests Problems with Iran's Nuclear Effort -William J. Broad

International Atomic Energy Agency inspectors reported that when visiting the main Iranian enrichment plant at Natanz on Nov. 16, they found that engineers had stopped feeding uranium into the long rows of centrifuges. Six days later, Iran said it had restarted the process.

Independent experts suggested that the computer worm suspected of being aimed at Iran's nuclear program had caused the machines to break down. David Albright, president of the Institute for Science and International Security, said the new disclosures made incapacitation from the Stuxnet worm "sound more credible."

American officials have not claimed responsibility for the worm, but they do say the Obama administration has stepped up a broad covert program, inherited from the Bush administration, to undermine Iran's nuclear program.
