German Authorities Find Al Qaeda Plans Disguised In Porn 332

According to CNN, which credits Hamburg-based newspaper Die Zeit, German investigators have uncovered a trove of more than 100 Al Qaeda documents recovered from a "digital storage device" (and memory cards) which were found hidden in the underpants of Austrian citizen Maqsood Lodin, who had recently traveled to Pakistan. The documents "included an inside track on some of the terror group's most audacious plots and a road map for future operations." Among these future plots: "[S]eizing cruise ships and carrying out attacks in Europe similar to the gun attacks by Pakistani militants that paralyzed the Indian city of Mumbai in November 2008." The documents were reportedly neither in plain view nor simply encrypted, but instead steganographically embedded in a pornographic video.

      We all know these religious zealots hate pornography! This must mean the reason they are doing this is instead to terrorize US citizens!!! How? From now on the TSA will request all pornography in your laptop or smartphone be carefully analyzed, frame by frame, before you board your flight!!! They may simply force you to trash your smartphones, laptops and tablets just like they do with your coke!

          I presume you're being facetious, but the topic actually came up in an article I was reading recently (in Slate, I think) about the life of women in a Bangladesh brothel and their conflict with the local clergy. The older women advise the younger women (sort of a master/padawan thing) that if they don't wish to engage in oral sex, to tell their customers that they refuse to do that because their mouths are used to recite the verses of the Koran.

        Correct. Most juries make their decisions based on emotional reasoning, rather than on the law. That's why so many people are in prison in this country compared to others, and also why so many innocent people are released from prison every year based on new evidence.

        Bear in mind this wasn't just a random stop-and-search, they already suspected he was an al-Qaeda member.

        The use of steganography is not exactly widespread; And despite the simplicity of the concept, most everyday people in this country couldn't tell you what it is, nor provide any examples of it. This is likely broadly true of the general population worldwide. So your argument here is invalid: The very use of steganographic techniques indicates an above-average level of technical proficiency.

          Dear Opportunist, America has juries with the intent to frustrate the government from always having its way, period: because of juries, the executive (who purports to act in the name of the law), legislative (who makes the laws), and judicial (who rules on the laws) can all be nullified and hindered by ordinary people: even if not particularly practicing "nullification" per se, they can at least hang trials over and over if something is questionable. So long as one analytical and logical reasoner is in the jury, and something about a trial is dubious, the motion against an accused fails: that is, at least, if that person gives a damn about being honest and upright. Far from being insensible and stupid, it's a feature: get over it. Note that it's not just the government, but the accused as well, that can appeal to the emotions of a jury.

        Hiding data in your underpants is very suspicious.

        Keeping a steganography program along with the data is very suspicious.

        Having a big stash of porn if you're a fundementalist is a little bit suspicious.

        All those are independent.

        The fact it was in his underwear is definitely relevant, since the whole point of steganography is to hide. Every time you do something suspicious to make people look harder, you defeat the purpose of the steganography.

        If it was a memory card in his backpack, in his camera, which matched his camera, had consistent dates and had a bunch of touristy videos on it and nothing else, they might wehh lave not looked any further.

        Of course they might have done.

        But if most of the files were chaff and had embedded random data (to make the noise levels match) and one had encryped data, even with a moderately good password, they might well have wasted a ton of time on the wrong files and given up.

        The fact he had it hidden in his pants pretty much guaranteed that they looked until they found something.

        Of course if he'd done all that and had a really good password, they would have been SOL, either way. They would have probably been very suspicious, but unable to prove anything either way.

    Without knowledge of the algorithm and key, with any even remotely good stego and crypto it sould be impossible to prove that anything is hidden, since good crypto looks like perfetly random data.

    Even if the authorities strongly suspect that there is stego'd data, and they know the algorithm, the best they can do is extract a list of random bits corresponding to what they believe to be hidden.

    If the setgo algorithm is sound, then there is no way of proving that the data source isn't just a bit noisy.

    Then, there should be no way of decrypting the data, or even proving it is non-random.

    Unless they used a very weak password, and the authorities new enough about the organisation to have a limited pool of crypto and stego algorithms to try.

    Either that or they inferred the most likely one time pad, based on the presence of a beard and arabic sounding name on the suspect.

    • I can't claim to be an expert on the topic, but there are likely statistical methods to determine the probability that an image is naturally noisy, or made so by artificial means (i.e. proof that steganography is present). Even in extreme cases the crypto would still protect the message itself, until someone pulls out the $5 wrench.

They are probably under the assumption that trying to encrypt something (A) is a waste of time if they are likely to have the resources to break it and (B) will attract attention.

      Analysis of randomness is quite an advanced science. It's not nearly as difficult as you might imagine to spot an anomaly in random data. Few things in life are truly random, and if you are familiar enough with the kind of randomness in something, you will have a very good statistical chance of noticing it.

      As for the steno itself, there's a double-edged sword there. The same as encryption, only a fool designs his own. Without a really deep understanding of encryption it's easy to make a subtle mistake in you design that introduces a significant weakness. So on that hand we have to assume they are using something at least somewhat commonly available. But that's where the other edge gets you... it becomes MUCH easier to spot steno'd data when you are checking for a list of specific methods of steno. The analysis tool will scan the data against dozens or hundreds of common tools, and draw a nice graph with the line mostly hanging around the 2% point at the bottom, except for one eyesore of a spike for one of the tests. Then they take off the gloves and get to work.

      Just tossing out a very basic example, lets say they are steno'ing encrypted data into a big tiff by overwriting the LSB on teach byte. Visually you won't notice this because the difference is too small Mathematically the data you're storing is more-or-less flat random. BUT the data you replaced ISN'T. The LSB in an image is far from noise, and will have areas that are related by their relative position in the image. This will stick out like a sore thumb when you run a little analysis on the bits in the image. It'll be too random. And at this point your steno is busted, and it comes down to breaking the encryption. The lesson there is pretty basic - encrypted data will stick out about as well as data in the clear. All you're doing at that point is buying a little time. And intel agencies are both persistent and patient. You're better off investing more time in better steno.

      To throw in an analogy, look at smuggling. If a truck is being searched at the border and the smugglers did a good job distracting from the small hide where the goods are, they get past the checkpoint with zero problem. It doesn't matter if the goods are in a safe in the hole or just tossed in a grocery sac, being in a safe didn't help. On the other hand, if the guards notice the missing volume, you're done. It doesn't matter how well you've concealed the opening, it doesn't matter how sturdy the latch, it doesn't matter if the goods are in a safe. You've been found out, and you're done. They will tear the truck apart until they get into the hole, and bust open the safe. The same principles are at work with steno.

      Both the stego and the crypto could actually be excellent and still be systematically weakened by a PEBKaC or even other layers. A few ideas off the top of my head...

      Maybe the flash drive contained not only the data, but also some executable stego software (kind of like how having TrueCrypt installed, as an add-on rather than something coming in all default installs, is a way of announcing "hidden volumes very likely exist on this system").

      Maybe the stego and crypto application software is excellent, but some other layer (e.g. the OS) left clues. Perhaps he occasionally updated the archive (it sounds like the movie contained multiple files), adding to it, and every time he used the stego software to write out a new file, the OS left copies of the file's previous contents sitting around in free space. (Ooh, or maybe the flash drive's own wear-levelling management: he copied the video to the drive once, then the video was updated and he copied the updated one "over" it onto the same drive -- bingo, this is my first guess as to what actually happened. I bet lots of not-necessarily-stupid people would make this mistake.) Then investigators notice two copies of the "same" video with different binary representations. Stego alert.

      Maybe all the tools were perfect, but the user was an idiot. Perhaps after the guy's capture, they gave him back his flash drive and let him use a computer, and then he cooperatively typed his passphrase into the government's friendly computer, while thinking, "Muahaha, stupid infidels, now I will use this opportunity to delete my^H^H the only copy of the secret plans! I am so clever and they are so dumb!"

      You can have good tools and still deploy them stupidly or use them stupidly. Or just foolishly enough, to tip your hand that you're hiding data. After that, decryption passphrase is recovered with a $10 wrench.

  • I can't remember the name of the film, and it was not exactly modern stenography, but the plot was the Russians were sending secret messages to and from their embedded spies in the States via a series of porno videos.

    Messages were being encoded as bar code segments used to make up the wall paper behind the 'actors'

  • On May 16 last year, a 22-year-old Austrian named Maqsood Lodin was being questioned by police in Berlin. He had recently returned from Pakistan via Budapest, Hungary, and then traveled overland to Germany. His interrogators were surprised to find that hidden in his underpants were a digital storage device and memory cards.

    Yeah, steganography pretty much fails when you shove the thing up in your ass. Law enforcers tend to find that suspicious.

    Osama's wife: Do you always look at it encoded?

    Osama: Well you have to. There's way too much information to decode the movie in realtime. You get used to it. I...I don't even see the blonde, brunette, and red-head. All I see is our nefarious plots. Hey, you uh... want a drink?
  • I've been wondering for a long time whether spam is not also a means for them to disseminate instructions in some way. It doesn't appear to come from an identifiable source, and does not seem directed at any particular recipient, but the people who expect to find something there would be able to find it.

    Crazy fanatic dad : "OH NO!!! you have been corrupted by the filthy western decadance!! "
    Muslim kid : "No dad!! look im using their own flithy videos against them, by hiding cunning terrorist plans inside them!! honest!!"
    Crazy fanactic dad : "Ahh good son. Well done carry on"

    Muslim kid (whispers) : "sucker! heh heh "
  • The "suspect" will never know ... As the "authorities" have undoubtedly discovered already.

    Importing porn to Germany from Pakistan is about the most suspicious thing anyone can do.

  • Now they get to sit around watching Al-Qaeda videos so they can keep a eye out for the naughty bits.
  • Hiding it in port is probably a great recruitment tool!!!

  • I find very surprising that they could find&decrypt the steganography: AFAIK, the first step is to encrypt the document and compress it, making the document "look like" a random number.
    Then you mix the document with the movie..

    So either the terrorists were lazy/stupid or there's something strange here: how did they find the hidden countent?

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
