Stuxnet, the first cyber warrior, stalls Iran’s nuclear ambitions

Targeted attack fells enrichment facility

Vancouver Sun--The computer virus attack on Iran’s uranium enrichment plant at Natanz is the first documented offensive on the battlefield of cyber-warfare.

But even though what happened at Natanz at the end of 2009 and early last year has been exhaustively dissected by independent analysts such as those at the Institute for Science and International Security (ISIS) in Washington, D.C., there are still many questions.

For example, the precise aims and therefore the level of success of the attack are not known.

What is clear is that the computer virus known as Stuxnet was designed specifically to target the electronic systems controlling the speed of the ranks of thousands of two-metre tall centrifuges Iran uses to spin and thus concentrate the gas uranium hexaflouride.

Iran says it is only enriching uranium to the low levels required to make fuel for civilian nuclear reactors, but most of the rest of the world believes Tehran is trying to acquire the capacity to make highly enriched uranium suitable for manufacturing nuclear weapons.

Stuxnet, which has been described by a computer security expert as "a marksman’s job," was written specifically to increase the wall speed of the Pakistan-designed IR-1 centrifuges obtained illicitly by Iran to nearly 450 metres a second.

Those who know about the Iranian uranium enrichment system -and whoever designed Stuxnet knew in great detail about the centrifuges right down to which companies supplied the speed control systems and how they worked -would realize that at that speed the centrifuges would simply fly apart and shatter.

That seems to be what happened to 984 of the enrichment machines between November 2009 and the end of January 2010. Continued…

Hong Kong to pass laws to seize Iran-linked assets

AFP— Hong Kong said Wednesday it was "striving" to pass legislation to comply with UN sanctions against Iran, after 20 shipping firms in the city were accused of being linked to Tehran’s weapons buildup.

Last week, the US Treasury Department slapped sanctions on 24 shipping companies, including four in Britain’s Isle of Man, accused of being fronts for Iranian businesses involved in Iran’s missile programmes.

The firms are allegedly affiliated with the Islamic Republic of Iran Shipping Lines (IRISL), which has been slapped with international sanctions.

Hong Kong, a semi-autonomous Chinese territory, is awaiting Beijing’s final approval to usher in the changes, but China has said it would support the sanctions passed by the UN Security Council in June last year.

At present, Hong Kong cannot seize assets belonging to the IRISL-linked shipping companies without first obtaining a court order.

"We are preparing the necessary subsidiary legislation to... give effect to new sanctions against Iran," Hong Kong’s government said in a statement Wednesday, adding it was "striving to complete the work as soon as possible."

The government did not immediately provide details about when it had last sought a court-issued warrant to seize assets.

James To, head of Hong Kong’s Legislative Council security panel, said the new laws would be passed in the "very near future".

"The process should be very quick", he told AFP.

"I can see no problem with it all, given that China is a member of the UN Security Council".

The US has stepped up its efforts to isolate Iran-linked commercial entities tied to its military development programmes since the Security Council imposed a fourth set of sanctions against Iran in June 2010.

Observers have said firms dodging sanctions or engaging in other illicit activity often look to Hong Kong for cover given the ease of registering a business in the city, which is also a major shipping hub.

In November, Hong Kong authorities detained a cargo ship linked to IRISL over an alleged loan default with a group of European banks.
