Iran’s nuclear trouble continues

A new computer virus that seemed to be targeting Iranian government facilities has been discovered. Iranian officials announced last week that they had detected a new attempt to infiltrate government computers. Public acknowledgement of this new virus, now called ‘Stars’, comes less than a year after the 2010 revelation that a separate virus, Stuxnet, was responsible for the difficulty the Persian nation has encountered in operating its uranium centrifuges. Iranian officials, along with several prominent western cyber-security experts, have attributed the origin of Stuxnet to the United States and Israel. Neither the US nor Israel has accepted responsibility for the virus. Little information is as yet publicly available about the newer Stars virus although it reportedly takes the form of official-looking data and is ‘hard to eliminate in its original form.’ [GSN]

Iran has acknowledged that its enrichment efforts had been delayed by the earlier Stuxnet virus. The virus violently manipulates the spinning speed of rotors inside centrifuges used to separate isotopes of uranium. While doing so, it reports normal operating conditions to the control mechanism thus avoiding an emergency shutdown. The P1 centrifuges being used by Iran are highly sensitive machines and the sudden increases and decreases in speed that Stuxnet subjected them to would have undoubtedly rendered them inoperable. Some speculate that code contained in Stuxnet could cause the centrifuges to literally explode.

Ralph Langer explains Stuxnet

Experts believe that Stuxnet has set back any Iranian program towards a nuclear weapon – real or imagined – by several years. This no doubt gives Israel some breathing room in its debate about a possible preventive strike, ala its universally condemned 1981 destruction of the Osirak nuclear reactor which was under construction in Iraq. (It’s worth noting that while the Osirak facility was destroyed, many contend that the strike may have actually accelerated Iraq’s nuclear weapons program.) Regardless, with the emergence of this new cyber attack, it’s clear that somebody has decided to devote considerable resources to sabotaging the Iranian nuclear program. The level of sophistication and explicit objectives of these viruses, coupled in consideration with last year’s assassinations of Iranian nuclear scientists, certainly limits that list of potential somebodies.
