• Israel, with U.S. help, tested Stuxnet at Dimona before attacking Iran

    The New York Times quoted intelligence and military experts to say that U.S. and Israeli intelligence services collaborated to develop a destructive computer worm to sabotage Iran’s efforts to make a nuclear bomb; the Stuxnet computer worm shut down a fifth of Iran’s nuclear centrifuges in November and helped delay its ability to make its first nuclear weapons; before using Stuxnet to attack Iran’s nuclear program, Israel has tested the effectiveness of the malware at the heavily guarded Dimona complex in the Negev desert which houses Israel’s undeclared — and the Middle East’s sole — nuclear weapons program

  • Iran: Mossad targeting scientists

    Iran says it has arrested members of a an Israeli spy network responsible for targeting Iranian nuclear scientists; Israel has a history of killing nuclear scientists of neighboring states embarking on nuclear weapons programs — this was the case with Egyptian scientists and their European helpers in the early 1960s, and with Iraqi scientists in the 1980s; the assassination of a dozen or so leading Iranian nuclear scientists has also been linked to the Mossad

  • Geologists develop way to monitor covert nuclear tests in the Middle East

    Not only is it difficult to identify exactly where an explosion takes place, but it is especially challenging to differentiate the seismic waves generated by nuclear explosions from those generated by earthquakes, volcanic activity, and mine collapses; geologists develop improved seismic model for monitoring nuclear explosions in Middle East

  • Experts: Iran's threat to kill U.S. generals is serious

    Iran’s anger at the massive blow the Stuxnet malware has inflicted on its nuclear weapons program boils over; the commander of Iran’s Revolutionary Guard, Gen. Mohammad Reza Naghdi, threatened that American generals will be targeted and killed in revenge for last week’s attacks on two of Iran’s leading nuclear scientists; Iran and Middle East experts say that Iran often makes outlandish threats, but that this one has to be taken as a serious and credible threat because it came directly from Naghdi; the most likely place for an attack to occur would be Iraq, and any attack would most likely be carried out by surrogates working for the Iranian Revolutionary Guard; Bahrain, Qatar, and other Gulf states would also allow the Iranian general to carry out the threat

  • Stuxnet virus set back Iran's nuclear weapons program by two years: Langner

    Ralph Langner, top German computer security expert and the leading authority on Stuxnet, says Stuxnet was as effective in disrupting Iran’s nuclear weapons program as a direct military strike — but without any fatalities; the malware has set back the Iranian program by two years; expert says the Israeli military was the likely creator of the virus

  • Aussie intelligence chiefs fear nuclear war between Israel and Iran

    WikiLeaks documents show that Australian intelligence agencies fear that Israel might launch military strikes against Iran and that Tehran’s pursuit of nuclear capabilities could draw the United States and Australia into a potential nuclear war in the Middle East; Australia’s top intelligence agency also says that Iran’s nuclear program is intended to deter attack and that it is a mistake to regard Iran as a “‘rogue state”

  • Experts: Stuxnet worm wreaks havoc at Iran's nuclear sites

    Iran’s nuclear program is still in chaos as a result of the Stuxnet attack; the American and European experts say their security Web sites, which deal with the computer worm known as Stuxnet, continue to be swamped with traffic from Tehran and other places in the Islamic Republic, an indication that the worm continues to infect the computers at Iran’s two nuclear sites; Stuxnet was designed to take over the control systems and evade detection, and it apparently was very successful; last week President Mahmoud Ahmadinejad, after months of denials, admitted that the worm had penetrated Iran’s nuclear sites, but he said it was detected and controlled; the second part of that claim, experts say, does not ring true

  • Wikileaks: North Korea "helps Burma with nuclear sites"

    U.S. diplomatic cables released by WikiLeaks reveal that Burma may be building missile and nuclear sites in remote locations with support from North Korea; the documents cite witnesses who say North Korean workers are helping Burma construct an underground bunker in a remote jungle; one cable reads: ‘The North Koreans, aided by Burmese workers, are constructing a concrete-reinforced underground facility that is ‘500 ft from the top of the cave to the top of the hill above’”

  • Medical isotopes no longer require weapons-grade uranium

    Highly enriched uranium (HEU) is used in nuclear weapons, but it is also used to make the radioisotopes that are injected in tiny quantities into people to diagnose and treat disease; indeed, making medical isotopes is a time-honored excuse for enriching uranium, if you want to build nuclear weapons but do not want to admit you are doing so (this is the cover Iran is using for its bomb-oriented enrichment program); South Africa’s Pelindaba reactor is now producing medical treatment-oriented molybdenum-99 (Mo-99) made from low-enriched uranium

  • FedEx loses -- then finds -- radioactive rods

    The shipment of radioactive rods sent from Fargo, North Dakota, to Knoxville, Tennessee, posed little threat, but its misplacement underscores the need to track low-hazard materials that could be used in small-scale terrorist attacks, experts say; as al Qaeda has shifted its tactics from 9/11-scale attacks to smaller attacks which aim to create fear and do economic damage, there is growing concern about low-radiation materials which are widely used in research, medical facilities, and industry; such materials may not be suitable for a nuclear bomb, but could be used to create “dirty bombs,” which cause fewer casualties but can release hazardous materials when they explode

  • IAEA: Iran forced to stop enrichment on 16 November

    The UN International Atomic Energy Agency (IAEA) reported Tuesday that Iran’s uranium enrichment program had shut down a week ago; the stoppage of the enrichment program coincides with the release of detailed expert studies of the Stuxnet virus; the conclusion of the cyber experts is that Stuxnet was aimed not at Iran’s Bushehr nuclear reactor, as initially thought, but rather at destroying Iran’s centrifuge farms; the sustained cyber attacks has already reduced the number of operating centrifuges from 4,920 in May 2009 to 3,772 in September 2010; it appears that the covert campaign Israel and the United States has been conducting against Iran’s nuclear weapons program — a campaign which includes the assassination of Iranian scientists and engineers, blowing up of machinery and supplies, attacks on Revolutionary Guard facilities, and seizing of technology shipments to Iran — is beginning to take its toll

  • Spotting illicit nuclear activity from a distance

    French scientists unveil a plan to place antineutrino detectors off the coast of rogue nations suspected of operating clandestine nuclear reactors; their idea is to turn a supertanker into an antineutrino detector by kitting it out with the necessary photon detectors and filling it with 10^34 protons in the form of 138,000 tons of linearalkylbenzene (C13 H30); the plan is to sink the tanker in up to four kilometers of water off the coast of a rogue state, and the supertanker would then watch for the telltale signs of undeclared antineutrino activity

  • North Korea enriches enough uranium for two nuclear bombs a year

    A report by three Western visitors to North Korea says North Korea is now operating an industrial-scale centrifuge farm to enrich uranium, with up to 2,000 centrifuges; the plant could make 30 to 40 kilograms of highly enriched uranium per year, enough for one or two nuclear weapons has

  • Nuclear DUI: DOE IG finds cause for concern

    There are about 600 OST (Office of Secure Transportation) agents — that is, drivers who have permits to haul nuclear weapons, weapons components, and special nuclear material (SNM) around the country; the Department of Energy inspector general investigated reports that some of these drivers are drunk on the job; a new report found 16 incident, of which 2 were of “particular concern”

  • U.S., Kazakhstan complete secret transfer of Soviet-era nuclear materials

    In the largest such operation ever mounted, U.S. and Kazakh officials transferred 11 tons of highly enriched uranium and 3 tons of plutonium some 1,890 miles by rail and road across the Central Asian country; the nuclear material, which could have been used to make more than 770 bombs, was moved from a facility feared vulnerable to terrorist attack to a new high-security facility
