イスラエル:対イラン攻撃をする必要性は3年先延ばしされた

(1つ目)Stuxnet wormは、イランのウラン濃縮装置1000機を破壊した。

(2つ目)これにより、イランの核開発計画は3年遅れた(=対イラン軍事攻撃をする必要性が2011~13年まで先延ばしされたので、米国による外交努力に期待するというイスラエル退役軍人の発言)。

(ユダヤ人がエラそうなことを言っているが、山火事1つを自力で消せないイスラエルが対イラン戦を始めるわけにはいかなくなったというのが本音だろう。)

Symantec社がStuxnetに関する分析を発表しているが、そのうちこちらの記事によると、Stuxnetはマレーシアとデンマークのサーバーに感染し、そこを起点にして、指示されたIPアドレスを攻撃したそうだ。マレーシアとデンマークのサーバーはほどなく閉鎖されたが、別のサーバーに転移し、自らもバージョンアップを繰り返して、最終的にイランに到達した。

攻撃された国は、多い順にイラン、インドネシア、インド、アゼルバイジャン、パキスタン、米国、その他。(古い記事を見ると、最初はインドが一番攻撃されていた。勝手に想像すると、攻撃対象と同じ機器が普及しているのだろう。)

こちらの記事には、パイプラインに突然負荷がかかり、広島型原爆の5分の1の強さの爆発が発生した、とある。

そっか、イスラエルはこういう悪いことをするのか。家電製品をネットワークでつなげる構想が日本でも進行中だが、なるべく単独で使うのが安全だ。壊されても損害賠償を請求する相手を見つけることができない。



Stuxnet may have destroyed 1,000 centrifuges at Natanz

Malicious computer virus accelerated, wrecked motors and may have decommissioned uranium enrichment centrifuges, think tank concludes.

The Stuxnet virus that has infected Iran's nuclear installations may have been behind the decommissioning of 1,000 centrifuges at the Natanz uranium enrichment facility earlier this year, according to a new analysis of the malicious software.

Prepared by the Washington-based Institute for Science and International Security, the paper raised the possibility that the reported breakage of 1,000 centrifuges was caused by the virus.

According to the paper, the timing of the removal of 1,000 centrifuges was consistent with a statement made last month by Ali Akbar Salehi, then-head of Iran's Atomic Energy Organization and recently appointed as the country's foreign minister, who confirmed in an interview: "One year and several months ago, Westerners sent a virus to [our] country's nuclear sites."

There are currently approximately 10,000 IR-1 centrifuges installed inside the Natanz uranium enrichment plant, according to the report.

Last week, The Jerusalem Post interviewed Ralph Langer, a top German computer consultant who was one of the first experts to analyze Stuxnet's code. It was possible the worm had set back Iran's nuclear program by two years, Langer said.

Widespread speculation has named the IDF's Military Intelligence Unit 8200, known for its advanced signal intelligence capabilities, as the possible creator of the software, or perhaps the United States. Langer said last week that in his opinion at least two countries were behind Stuxnet.

Last month, the International Atomic Energy Agency, the United Nation's nuclear watchdog, said that Iran had suspended work at its nuclear field-production facilities. While it did not specify a reason, Stuxnet was assessed to be one of the likely culprits.

David Albright, president of the Institute for Science and International Security, told the Post that during a study of the Stuxnet code, he discovered that the virus caused the engines in Iran's IR-1 centrifuges to increase and decrease their speed. The report cited an unnamed government official who claimed that Iran usually ran its motors at 1,007 cycles per second to prevent damage, while Stuxnet seemed to increase the motor speed to 1,064 cycles per second.

"If you start changing the speed, there are vibrations and they become so severe that it can break the motor," Albright said. "If it is true that it is attacking the IR-1, then it is changing the speed to attack the motor."

Albright said that the number of centrifuges damaged – 1,000 – also appeared to indicate that Stuxnet – if it caused the breakage – was meant to be subtle and work slowly by causing small amounts of damage to the systems that would not make the Iranians suspect that something foreign – like malware – had been infiltrated into their computers. "It could be that Stuxnet was meant to be subtle to disrupt and break more and have less enriched uranium produced," he said.



Deputy PM: West has three years to stop Iran nuclear program
Moshe Ya'alon says Iran remains the government's biggest worry, hopes for success of U.S.-led actions against Teheran.

The United States and its allies have up to three years to curb Iran's nuclear program, which has been set back by technical difficulties and sanctions, Deputy Prime Minister Moshe Ya'alon said on Wednesday.

Saying Iran remained the government's biggest worry, Yaalon did not mention possible unilateral military strikes by Israel, saying he hoped U.S.-led action against Tehran would be successful.

"I believe that this effort will grow, and will include areas beyond sanctions, to convince the Iranian regime that, effectively, it must choose between continuing to seek nuclear capability and surviving," Ya'alon told Israel Radio. "I don't know if it will happen in 2011 or in 2012, but we are talking in terms of the next three years."

Ya'alon, a former armed forces chief, noted Iran's uranium enrichment plan had suffered setbacks. Some analysts have seen signs of foreign sabotage in incidents such as the corruption of Iranian computer networks by a virus.

"These difficulties postpone the timeline, of course. Thus we cannot talk about a 'point of no return'. Iran does not currently have the ability to make a nuclear bomb on its own," Ya'alon said. "I hope it won't succeed at all and that the Western world's effort will ultimately deny Iran a nuclear capability."

Ya'alon had previously been hawkish on Iran, saying Israel, believed to have region's only nuclear arsenal, should attack Iran rather than see it get the bomb.

Other officials, including Prime Minister Benjamin Netanyahu, have been tight-lipped about the military option, which would face big tactical and diplomatic hurdles.

Iranian President Mahmoud Ahmadinejad said on Tuesday Iran will retain its right to pursue nuclear technology.

Speaking about next month's planned nuclear talks with world powers in Istanbul, Ahmadinejad said "We are willing to cooperate with [them] in Istanbul, but all of them should acknowledge Iran's right to pursue nuclear technology and know that we will not retreat on inch from these rights."

The six world powers - Britain, China, France, Germany, Russia and the United States - demand that Iran suspend its controversial uranium enrichment, in line with five United Nations Security Council resolutions, four of them with sanctions, designed to make sure the Islamic state is not pursuing a secret military program.

While denying the existence of military nuclear programs, Tehran has referenced its right as a Nuclear Non-Proliferation Treaty signatory and International Atomic Energy Agency member, saying, like any other country, it has the right to have civil nuclear projects, including uranium enrichment.
