Hacking Nuclear Command and Control 256

The Walking Dude writes "The International Commission on Nuclear Non-proliferation and Disarmament (ICNND) has released an unclassified report exploring the possibility of cyber terrorists launching nuclear weapons. Ominous exploits include unreliable early warning sensors, unsecure nuclear weapons storage, transportation blunders, breaches in the chain of command, and the use of Windows on nuclear submarines. A traditional large-scale terrorist attack, such as the 2008 Mumbai attacks, could be combined with computer network operations in an attempt to start a nuclear war. Amidst the confusion of the traditional attack, communications could be disrupted, false declarations of war could be issued on both sides, and early warning sensors could be spoofed. Adding to this is the short time frame in which a retaliatory nuclear response must be decided upon, in some cases as little as 15 minutes. The amount of firepower that could be unleashed in these 15 minutes would be equivalent to approximately 100,000 Hiroshima bombs."

          That is absolutely correct. That is how accidents happen. But if you or I or McVeigh planned to force "a critical density of 'coulds'," it would never work. Hollywood allows for failures on cue and long chains of helpful improbabilities, but outside the movies perfect storms don't follow a plan.

        When assessing your adversaries, you always assess capability, not probability or even intention. "Can't possibly" is acceptable, but improvable. "Might" raises serious concern. "Could" is reason for all-out batshit-crazy paranoia.

        And I like that things are that way. At least, y'know, when dealing with unauthorized nuclear launches.

        My next-door neighbour, a middle-ranking officer on the UK's Vanguard fleet of nuclear submarines, asked me to fix his laptop ready for the recent 3-month wargame off Florida. Naturally, the "fix" was as simple as identify trojan, format, re-install MS-Windows, install Avast, advise him not to run keygens he'd randomly downloaded off a torrent, and slip an Ubuntu live CD into the laptop bag in the hope it'd pique his interest.

        As I returned it to him, I said "I turned WiFi and Bluetooth off by default. I assume you'd get in trouble if your stealth-sub got spotted by something as simple as your opponent searching for available networks."

            Wi-Fi is 2.4 GHz... The Navy used to use ELF radio to communicate (communicate = notify to surface so we can send you something at >.001bps) with submerged subs - according to Wikipedia the frequency the military used was around 60-80Hz (at the high end of ELF). It has to be that low freq to get that deep, and you need to drag a huge antenna wire behind you. I think Wi-Fi is probably safe, since by the time you were close enough to find the signal, you could just plug a cable into the sub's external ethernet jack.

    From personal experience I can say that 'Windows on a submarine' really isn't an issue. The Navy uses at LEAST three independent networks on their ships. Two that I was told about and one that I wasn't supposed to notice on my own. These aren't connected together, and only one of them connects to the outside world. Even if they were running a completely un-patched version of Windows 3.11 on that inner-most network, they're still as secure as they need to be.

    In the case of the Navy's most important systems, they're not secured via copper but instead by steel-jacketed lead.

    • Ah but you forget, the systems are connected by the most insecure component of all - people. If the people are fooled into pushing the shiney red button by misinformation delivered by the other systems, what does it matter?
  • by Fantom42 ( 174630 ) on Thursday July 23, 2009 @07:44AM (#28794031)

    The use of Windows on nuclear submarines is not a big deal without providing a lot more context. Is Windows being installed to perform a critical function? Is there an independent backup implemented in hardware? There remain a lot of questions to be answered before I care that Windows is installed on submarines, especially given the alarmist tone of the paper as a whole.

    The article (mis?)cited even talks about how the systems being used don't "usually" get autonomous control of the weapons systems. (http://www.theregister.co.uk/2008/12/16/windows_for_submarines_rollout/) That's pretty vague, but not really surprisingfor a reporter.

    So, is Windows on submarines a concern? Sure it is. Quite frankly, (get out your -1 mod points) for a high risk system, one in which failure can cause loss of life on a massive scale, using Linux, or any computer system is a concern.** Luckily, if engineers are doing their jobs correctly, they know how to design these systems to prevent a software failure from causing one of these events. This almost invariably means using custom software or (better) simple hardware to implement/interlock critical functions and use regular COTS software for the rest. And yes, false indications are an example of a critical function. If the software were to indicate a missile launch, for example, I would expect a way to verify that using hardware in the procedure before moving on to the next step.

    ** This is because any of these systems are too big to have the kinds of quality steps needed for such a system (think TRACEABLE code coverage, testing, requirements traceability, application of coding standards and other software engineering principles, all must be traceable). Maybe if Linus Torvalds and everyone who works on the Linux kernel was hired by the DOD and held to a software quality standard, like DO-178B (http://en.wikipedia.org/wiki/DO-178B)*** there would be a small chance of being able to use this software for a function that is required to prevent loss of life.

    *** Having dug through DO-178B, it is not without its issues, either. But its a good starting point at least.

    • Not to mention there are dozens of networks at military installations, each of them seperated by an air-gap (meaning they're not connected to any others). IMO this report is mostly a scaretactic to try to make the US system look more vulnerable than it is. Most likely because there's an agenda to dismantle the whole she-bang.

  • Another vulnerability could be commanding officers learning new computer languages. Once you dig down enough in windows internals, maybe your mind starts thinking that mass blue screens and deaths are ok, and order a launch when distracted.

    Mutually Assured Destruction or Destruction. Asymmetrical use of a captured Nuclear weapon is surely a nightmare scenario, but a disarmament solution requires careful consideration.

    Some who have read my criticisms of the Nuclear Industry may be surprised to find that I actually support the development of a reactor that addresses the issue of 70,000 tons of Pu-239 (and much more U-238) currently stored in reactor sites around America, simply because it's irresponsible for our generation to foist these issue onto later generations.

    One of the core reasons I support the development of such a reactor because it is capable of utilising weapons grade plutonium as fuel creating an impetus for disarmament and, hopefully, slowly defusing the asymmetrical weapons threat.

    Unfortunately, because there is no geologically sound Nuclear waste dump in operation it's totally inappropriate to discuss building a new reactor facility until a proper containment facility is available. Yucca mountain is not a suitable site because it is made of pumice and geologically active evidenced by recent aftershocks of 5.6 within ten miles of a repository that is supposed to be geologically stable for at least 500000 years. The DOE's own 1982 Nuclear Waste policy Act reported that Yucca Mountain's geology is inappropriate to contain nuclear waste, and long term corrosion data on C22 (the material to contain the Pu-239 and mitigate the ingress of water - yet another Yucca problem) is just not available.

    We need something made of granite. The only human made structure with the potential to last 10000 years is Mt Rushmore, so it has to be an engineering project of that scale, because the logistical problems of transferring the 70000 odd tons of Pu239 to the spent fuel containment facility are so involved that you want to get it right the first time and only do it once.

    Even doing that will probably take 30 years to complete, but there is more to it than that.

    I was a big fan of the Integral Fast Reactor [wikipedia.org] as a potential solution and in a way I still am. But the reality is 3rd and 4th generation reactors are a pipe dream because our material science is not advanced enough yet to produce a reactor design that will last the thousands of years it will take to use that fuel. If you are going to build reactors then do it properly and build a Terra-watt scale nuclear reactor facility the belly of a massive granite mountain with an attached waste facility and chomp up all your remaining plutonium or end all commercial nuclear activity altogether.

    Why? Because Nuclear power is energy intensive *after* the energy has been produced simply because said technology (material sciences) are not adequate to produce a Nuclear reactor that has a life span that matches the geological time frames of the fuel. This exposes the facility to all the issues associated with de-commissioning reactor sites every 4 decades or so. A reactor design that lasts at least 1000 years and is a closed loop, i.e. the plutonium goes in and nothing comes out (except electricity and possibly hydrogen) and avoids all the energetic costs associated with mining, enrichment and de-commissioning/demolition of the reactor.

    As long we are producing plutonium and there is no where for it to go we will have a Nuclear Weapons threat and this is the price we pay for opening that pandora's box. I don't hide the fact that I don't like the constant failure of the Nuclear Industry. But I'm also being realistic. I realise that the only way out of this mess is a well thought out and designed project because we have no other choice due to the nature of the materials. It entails redesigning the entire industry, and it's a long term solution. A well designed and secured facility resistant to attacks even from orbit because that's the type of 21st century threats it would have to face.

    But it has to be done properly, and I don't think privat

  • What is the purpose of this? To engender fear or something? Or just a bit of idle fantasy in the summer heat?

    Whatever the reason, a nuclear war doesn't just happen out of the blue; it is highly unlikely that there wouldn't be a long time before where the tensions were constantly rising, and it isn't very believably that that would happen either. The missiles don't start firing because El Presidente regrettably puts his coffee cup in the wrong place and pushes the red button.

    As Top used to say; "Whenever I get something like this, first thing I do is consider the source. And baby, just who the hell are you?"

  • Without going too much into detail - sending launch orders requires much more than simply hacking into the network (which are probably air gapped anyhow).

    The message has to contain certain authorization codes so the recipient knows that it's not only a valid order, but that it is a valid launch order (as opposed to a valid test or training order). Those codes are stored in a double sealed envelope inside a safe with an inner and outer door - and each combo is controlled by a different person.

Technology is dominated by those who manage what they do not understand.
