Computer Science Professor Mocks The NSA's Buggy Code (softpedia.com) 179

Posted by EditorDavid from the back-to-school dept.
After performing hours of analysis, a computer science professor says he's "not impressed" by the quality of the recently-leaked code that's supposedly from an NSA hacking tool. An anonymous Slashdot reader writes: The professor, who teaches Software Vulnerability Analysis and Advanced Computer Security at the University of Illinois, Chicago, gripes about the cryptography operations employed in the code of an exploit called BANANAGLEE, used against Fortinet firewalls. Some of his criticism include the words "ridiculous", "very bad", "crazy" and "boring memory leaks".

"I would expect relatively bug-free code. And I would expect minimal cryptographic competence. None of those were true of the code I examined which was quite surprising," the professor told Softpedia in an email.
If these were cyberweapons, "I'm pretty underwhelmed by their quality," professor Checkoway writes on his blog, adding that he found "sloppy and buggy code," no authentication of the encrypted communication channel, 128-bit keys generated using 64 bits of entropy, and cypher initialization vectors that leaked bits of the hash of the plain text...

      Agreed. Considering this in the context of "cyberweapon", many weapons have been poorly designed and/or rushed into service, so this may be par for the course. I haven't looked at the code myself, but I would imagine that having a small footprint, both in terms of size and resources, is key to running undetected. Cutting corners, minimal encryption... those could be considered advantages here.

        I think that's a somewhat strong statement. You want your code to work when you deploy it. It's supposed to work. If it works, then it's a working weapon. If it has bugs that impede its function, then it isn't. If the tool can be used against the initiator, because the back channel isn't protected, then it's not just a weapon — it's a hazard.

        Sure, if you're using the "blast down the front door and storm through shooting" approach. On the other hand if you want to be a bit more subtle then your code needs to be tight and unobtrusive. The best attack is one that the defender never even knows about until it's far too late.

      Apparently, the bad code has been known to some secret services for some time. And that means that other secret services had the time to exploit the bad code and use it as an attack vector back against the NSA. I would be very wary to know that my opponent knows how shoddy my own code is. If for instance you can hijack encrypted communications, you can feed the communication any desinformation you want, and the original attacker believes it to be the real thing.

There was a narrow window where they'd at least consider one, back when people started talking about design patterns. These days it's next to impossible to get one approved, even if there's pretty good justification for it.

With that said, my general policy is that you generally shouldn't design classes that are limited to use as a singleton. You should always provide the ability to allocate additional instances unless it is impossible to safely have more than one instance for some reason (and you must justify why this is the case).

      That's possible, true.

      But it is hard to see that someone would "fix" that problem using the approach given in the code sample. Basically their "fix" only produced 64 bits of entropy for a 128 bit key, which is a 101-level cryptography mistake. It also took more time and was much more complex than a straightforward implementation, which kind of kills the argument about the authors having to work quickly. This is one of those screwups that required thought and effort. I'm left with two possibilities:

      (1) The NSA is hiring complete amateurs to write their exploit tools, and they aren't giving any adult supervision (or code reviews) to the products of those amateurs.

      (2) The NSA/Equation Group didn't write this code at all.

  • What if the shadow brokers didn't hack and steal NSA code, but simply had some part in writing the code to begin with and perhaps what they're selling is unrefined prototypes?

    Frankly I have no reason to believe that the shadow brokers and the equation group are even separate entities. If equation group are as good as they are supposed to be, then it makes more sense that for some reason equation group are playing a game with the public. (I highly doubt they'd try and play a game with the NSA.)

    Expert: I mean, look at it - it's a bunch of nails and duct tape around a low explosive core which doesn't have nearly the proper confinement for even 50% of the maximum shock wave capable, much less the ability to transition to detonation. And this wiring - that's just disgraceful - the solder didn't even flow properly here, and this is entirely unsheilded - anything could set this off accidentally, even a cell phone. If you were in my training program, you're fail miserably.

      I know. The professor admits he's not a cryptographer and then criticizes the way NSA forms a random number, which is a critical piece of crypto. Maybe they know something about crypto that he doesn't.

      You'd be right they'd fail the course and be booted out! And for good reason. I can assure you that you have special operations soldiers in the US who can and do use IEDs (for black flag, or deniable operations if nothing else) and you can be likewise sure that they will look like cobbled together crap (in case they're detected before they go off) but will not actually be crap. They'll go boom every time, because there's nothing worse than having a meticulously, planned and executed operation, months in the

    I'd like to see the professor brute forcing 64 bits to show exactly how weak that is.

  • ...at reverse engineering and cracking tend to be extremely 'pragmatic' in their approach to creating software.

    People are constantly confusing programming with software engineering. Look at Google for example, look at the design decisions behind golang. Google has lots of very smart people no doubt, but golang was designed around their pervasive weakness - they do not tend to be good software engineers (experience will usually lead them there though.)

  • "The purpose of the keygen tool is to generate a 16-byte random number for use by the other tools. This simple task can be accomplished by reading 16 bytes from /dev/urandom."

    No, not really - not if you want to maximize entropy. The procedure he describes afterwards seems awfully convoluted, but might be a good way of generating strong pseudorandom numbers in systems with a poor /dev/urandom implementation.
