Stuxnet Authors Made Key Errors 228

Trailrunner7 writes "There is a growing sentiment among security researchers that the programmers behind the Stuxnet attack may not have been the super-elite cadre of developers that they've been mythologized to be in the media. In fact, some experts say that Stuxnet could well have been far more effective and difficult to detect had the attackers not made a few elementary mistakes."

    "There are a lot of skills needed to write Stuxnet," he said. "Whoever did this needed to know WinCC programming, Step 7, they needed platform process knowledge, the ability to reverse engineer a number of file formats, kernel rootkit development and exploit development. That's a broad set of skills. Does anyone here think they could do all of that?"

    It's pretty safe to assume at this point that Stuxnet was developed as an Israel/USA military collaboration. Spokespeople from both countries smirk before saying "no comment" when asked about it. That being said, hackers have huge egos. The types of hackers that present at security conferences even more so. It's tremendously easy for them to pick apart the worm several months after it was discovered and say "oh ho ho, it doesn't encrypt it's command and control communications!!" like they're smarter than the people that built it.

      Easy; but not always invalid. Encrypted command and control communications have been standard in the better purely monetary botnets for at least a few years now.

      Everything is easier from the peanut gallery; but the notion that you have to be at least as good at your game as is a public-ally known strain of criminal in order to be considered for "super-spy" status seems like a very fair rule of thumb.

      I agree with the OP and want to mention another issue.

        Common encryption algorithms can be detected heuristically with high accuracy. Moreover, the original implementation/source code of the encryption can usually be identified. Perhaps the developers did not want the adversary to find out which implementation they used and for obvious reasons didn't want to use their own implementation. Also, when you use encryption, keys on the C&C endpoints are linked to the malware in a way that cannot plausibly denied -- not very desirable either.

    For those who don't RTFAs, this one has something interesting, not mentioned in the summary. The analyst thought the worm might have started as something else and been re-purposed for sabotage. There might be two separate coder groups, one who made the original program and one who made it into a weapon. The latter group was apparently less skilled, though still would have needed a considerable breadth of knowledge.

    Makes me wonder if the perpetrator might not be one of Iran's less advanced neighbours, instead of the US or Israel. After all, there are plenty of Middle Eastern nations who are worried about Iranian power and expansion. And there's two obvious suspects that would be blamed when it came to light.

    Of course, it could also be that either American or Israeli coders were rushed, understaffed, over-compartmentalized or otherwise had the quality of their work reduced.

    • It could very well have even been a group inside Iran. The recent elections have shown that there are a large group of people opposed to the current regime, most of them youth. Ahmadinejad's main claim to power is that he is protecting Iran from a US invasion(which yet another reason why W's war to avenge daddy was a huge mistake), if he can be shown to be inept at protecting Iran's military interests then he can conceivably be thrown out.
      • Probably a critical group from inside Iran won't have the knowledge of how to operate the centrifugues, let alone doing it stealthy and through commands in a virus...

    • The analysis is retarded. The worm didn't use sophisticated protection mechanisms because those significantly increase the likelihood the the payload wont ever get executed.

      Obviously in a situation like this trying to add obfuscation is entirely useless, either the payload is executed and the damage done or it's not.

    • I don't understand why it's assumed that ugly/bad code must come from developing countries. I have seen plenty of bad code coming out of US/Europeans. Unless there were comments in the code in a different language, there's no way to know who wrote it. In the end, it did its job.

    • Or how about the US, Israel, Russia, China, the UK and several other countries. If the US knew the Russians were behind it, do you think the CIA is going to announce it to the world, or just do as much damage by keeping their mouth shut. Probably several intelligence agencies knew what what was going on, but sometimes you can do more by knowing when to keep your mouth shut.

        I know your post was intended for humor, but I have a more serious question that maybe someone can answer...

        Did the modifications to the centrifuge control serve to damage the centrifuge, the contents of the centrifuge, or both? If the point was to damage the centrifuge, then the solution is determining why the centrifuges failed, correcting that, and ordering new centrifuges. If the point was to damage the nuclear material so that it isn't good enough to be used in a bomb, then the solution is to, again, determine why the centrifuges failed, and to figure out if it's possible to reprocess the material a second time to get it right, and if not, to start on a new batch of material. If the point was to do both, then not only do the centrifuges need to turn out bad product, but they have to do it subtly enough to not attract attention while the centrifuges slowly damage themselves, leading to a lot of bad product and a lot of bad centrifuges at the same time. Solution, determine the source of the problem, then replace the centrifuges and start processing again.

        I would think that the goal would be to make the Iranians involved *think* that they were getting the grade of Uranium Hexafluoride that they had planned on while instead delivering to them substandard product, so when they built weapons they had Uranium that either would reach critical mass or else wouldn't be nearly as efficient and would cause a much smaller boom. Achieving this would require not damaging the centrifuges yet damaging what they produce. This would allow an adversary of Iran to take this in to account in both diplomatic circles (being willing to push Iran harder despite the threat of a nuclear exchange) and in military ones (actively planning strategy considering nuclear fizzles), and if that's the case, this worm's discovery means that it's only a short-term problem for the Iranians, not a long-term problem that would allow for strategic thinking. The discovery means that Iran is set back, not thwarted as it would have been if the worm had gone on undetected for years and years, and while expensive for Iran (even if they can reprocess existing product that wasn't processed right the first time), it's not damning to the long term goals.

        • by topham ( 32406 )

          The centrifuges in question are hard to acquire, difficult to maintain and impossible to rebuild from the scrap left over after a significant failure.

        • From what I read it basically made the centrifuge shake itself to death, possibly with some kind of oscillation... while it reported normal readings to the command console.

          While it may have been "sneakier" to throw off what the centrifuges were producing, it would have been a fairly temporary setback once discovered. Destroying the centrifuges after having processed radioactive seems like it would leave a big mess and cost a lot to replace.

    It may very well be that the lack of proper cloaking was intentional, for at least two reasons : on the one hand, as long as the aim was reached, there was no need to reveal the full scope of expertise put behind it. Better keep still unknown cloaking techniques in case they may come handy in the future. On the second hand, stuxnet is certainly as much a psychological weapon as it is a technological one. What would be the interest to disrupt Iran's nuclear program if nobody knew what happened ? As such, it's a very good deterrent : any would be rogue third world country willing to go nuclear knows "someone" will take offense and knows that this "someone" has the abilities to bring their program down. But at this point, nobody can pinpoint who this "someone" may be with plausible certainty.

      Yes, Israel WANTS the world to know what happened, and they want the world to know they were involved. This is why Mossad has been gleefully and publicly showing off that Iran's nuclear weapon development has been pushed back years.

      It is odd that a mission that was 100% successful (something even Iran won't deny) is being criticized for not being good enough. Maybe some researchers just wanted their names in the newspaper?

    • And as such, they now know to protect their networks with an appropriate 'air-gap' where critical infrastructure is concerned.

Air gap was already a well known practice, but it is based on the assumption no one will leak anything inside the protected part.
