NYT: NSA Put 100,000 Radio Pathway "Backdoors" In PCs 324

retroworks writes "The New York Times has an interesting story on how NSA put transmitters into the USB input devices of PCs, allowing computers unplugged from the Internet to still be monitored, via radio, from up to 8 miles away. The article mainly reports NSA's use of the technology to monitor Chinese military, and minor headline reads 'No Domestic Use Seen.' The source of the data was evidently the leak from Edward J. Snowden."

How many people - even organizations like the Chinese military - are going to disassemble their USB cables and ports? If you're going to go to that far, you might as well build the device yourself out of off the shelf parts.

      I agree - however, there is the question of "who did they use them on?" and also that they were basically DESIGNED not to be detected.

      Most people who they targeted probably were arrested or they never even thought they were a target. In that case they can recover their hardware.

      The number of devices compromised is likely to be very small as a percentage of the devices out there. Almost certainly neither you or I have one of these devices in our kit. If we did have, how often have you popped open every keyboard/mouse/usb stick you own to make sure there's not something else in there that wasn't supposed to be?

      And if they are in collusion with even a single manufacturer to produce a compromised device, then you may never know about the devices hidden functions until you do a chip-analysis of everything inside the device (probably involving decapping and analysing the whole thing which can take years and decades of expertise).

      As such, it's unlikely you will ever see one, even with everyone on the Internet looking. That's also what I would expect if they were doing their job properly (or else these things would be discovered quickly and be useless to them).

      Much more importantly - if this is true, and we even if we start to use only trusted hardware, this is just more reason to have more "open" machines.

      Who knows what's inside a chip on your particular computer, even if it looks very similar to a mass-market item, if they could have got their hands on it and/or been the ones supplying it to you?

        That's kind of my thinking - that they would have to replace a discrete part within the laptop - possibly a motherboard, more likely a daughterboard or mini PCI device like a wifi card. If you replace the motherboard you'd have to deal with BIOS serial numbers etc which would be a PITA. The only way I can see this working is if it were done at a component level. Presumably the device would need to be connected to a data bus, e.g. USB/SATA? Or memory?
      • If they were really careful, it was packaged with an acid capsule, corrodes beyond analysis when opened, and can be remotely triggered to open the capsule with a hot-wire - obscuring the nefarious bits while preserving the expected functions. Might look like water damage or poor cleaning at the factory if it were ever opened.

        " mainly because a simple frequency scanner would allow one to detect the presence of transmissions by the device"

        Burst transmission. Buffer data for days, then send it all in a burst of under a minute. Nothing to detect unless the counterintelligence people are monitoring continually or get very lucky. It's old tech, dating back to the pre-IC days. Bugs back then did it by recording onto a magnetic tape. When the tape reached the end it turned on the transmitter and re-wound at high speed. The listeners then just had to play it back slowed-down and backwards to recover the original audio.

        I'm still skeptical, mainly because a simple frequency scanner would allow one to detect the presence of transmissions by the device, and because concealing an antenna, even in the form of a USB cable, would be difficult. If the cable is cut-off, then it would be massively obvious with a simple look underneath, and it would be difficult to manufacture a functioning USB cable that contained a radio and antenna. There was talk of manufacturer collaboration, especially against organizations that develop security (tampering with new-manufacture to replace components on the motherboards essentially) but that seems like it would be extraordinarily difficult to achieve without employees of the manufacturers questioning why they're going through so much effort to do this. We'll just have to see what comes of it. I'm genuinely curious if we'll ever see any actual evidence or not.

      Well, if a computer is poorly shielded that might not be all that hard. Handheld 5W ham radios can go much more than that distance on 2m, and lower frequencies can go much further. When the weather allows it, a 5W 2m transmission can go dozens or even a hundred miles, and in especially unusual weather conditions a friend of mine in California managed to talk with someone in Hawaii, once.

      So, while inside a case it might not go 20 miles to cover a whole city, I could see being able to reach 8 miles, depending on how intelligently the system was designed in order to reduce the chances of being discovered. The other downside is that strong radio transmissions can interfere with things including speakers, which might make them obvious if not handled correctly.
      • Lower frequencies require large antennas, and even on 2m, the device is sort of obvious. Ditto for 5W of extra power draw. If your supposedly EM-compatible PC or a similar device is emitting multiple watts in the VHF spectrum and you don't notice that, you fully deserve what you got.

        Honestly, I think the most efficient way of having the machine communicate with the attacker (especially if the attacker is NSA) is through some sort of TCP/IP based side channel. Low bandwidth, perhaps, but much less obvious.

      • If the transmitter is on the ISS, the signal will go much more than that distance, and receiver sensitivity is not the big trick - discrimination from other signals and noise is.

    • I'm surprised there's even a limit. Think about it for a while... the USB device only has to receive. Their transmitter can be as powerful as they want, so that's not a problem. To send data back, either the USB can store what it needs and be picked up later... or, it can infect the computer and use it to transmit. If it has ANY wifi capability, they can use that to transmit, and even if it doesn't I'd imagine there's all sorts of nifty tricks they could do like varying current draw in pulses to send a sign

      The NSA claims that it doesn't steal trade secrets from foreign companies in order to give US businesses a competitive edge. I suspect they are lying, given that it seems like they lie about everything, and that we already have reason to suspect they are lying about this in particular. [bbc.co.uk]

      However, the implication is that it would be wrong or immoral for them to do so (unlike the French or Chinese who have no such qualms). E.g., in the article, we read:

      At that session, Mr. Obama tried to differentiate between conducting surveillance for national security — which the United States argues is legitimate — and conducting it to steal intellectual property.

      It goes on to quote Peter Singer saying that for the Chinese, economic advantage is part of national security.

      Maybe the Chinese are right. And here's the thing - the U.S. already behaves as if securing economic advantages for our domestic industry is a critical interest. In trade negotiations, we ram our IP laws down the throats of every other country while dangling our domestic market in front of them, all the while never actually liberalizing agriculture at home. I don't understand why it's acceptable for us to promote our domestic businesses through trade diplomacy, but somehow it becomes unacceptable to do so through spying.

      In my mind, we are trying to accomplish the same thing as the Chinese, just via a different means (or probably, via both means). Yet we criticize them as if we are somehow morally superior in the way we do it.

      As an European, I don't care if US authorities spy on US citizens, that would be their own internal business. But I find it quite offensive that US spies on Europeans, in order to protect US interests. EU should really stand up and announce that such spying is totally unacceptable, any person caught to be part of such will serve serious jail time, diplomatic immunity or not.

        I'm dubious about the distance but remember that they are TARGETTING their devices.

        As such, they could be on a roof 12km away with a whole array of receivers pointed to within inches of the radio source, and so 12km isn't as insane as it sounds. But it doesn't mean they have a commercially viable tech that others don't.

        Pringles tins on wireless dongles - the range can be immense, and if you are good at antenna design, it can get insane. If you know to within-an-inch where you're supposed to be pointing at and/or can trigger it to do a one-off high-powered transmit to download information (by a similar one-off high-powered transmit from a distance), then it's not all that impossible.

    of 100k devices in the field isn't supported by the article.

    They infected 100k machines with software, most of them remotely.

    It's right there in the first two paragraphs of TFA:

    The National Security Agency has implanted software in nearly 100,000 computers around the world that allows the United States to conduct surveillance on those machines and can also create a digital highway for launching cyberattacks.

    While most of the software is inserted by gaining access to computer networks, the N.S.A. has increasingly made use of a secret technology that enables it to enter and alter data in computers even if they are not connected to the Internet

    • The easy MO is to to just hand out the USB devices at mil trade shows in China or Iran and other places where enemy officials will be. if 1% get inserted into a gov computer or sensitive target, that would be a great return on investment. It's not like this has to be targeted in any way.

  • So the only way to do this is get some sort of intercept from the manufacturer->seller/reseller->mail/postman. It looks like everybody is in cahoots with them.
  • Back a couple of decades ago, this was supposed to be possible remotely by monitoring RF output from those noisy, leaky VGA ports. Never saw a demonstration from 8 miles away, just across the street or from a van on the street. No special hardware in the computer, just the right gear to listen to the RF leaking all over the place.

    Sorry for no link, Google is full of connecting HDMI to VGA stuff these days.
    • By monitor I mean see what was on screen. I do not recall any demonstration of being to remotely manipulate input, data, etc.

      Yes. Here's the link.

      In theory, there is still some signal from modern LCD monitors, but it's much harder to pick up than the old CRTs. The same technology could be used to determine what a CPU is doing or any other electronic component, but, again, it's very difficult to get a strong enough signal at a distance to make use of it.

      • The thing I was remembering was the RF coming from the port itself, no matter if anything was plugged in or not. Saw them do the sniffing of laptops with open VGA ports too.
        • The CRT was a lot stronger source than just the VGA port but yes either of them (HDMI for that matter) are vulnerable to vanEck phreaking.

          • Yes, in some of those old reports, if memory serves, the big point was that your laptop is still vulnerable even if it is not connected to a CRT.

      Most people know of this from having read Cryptonomicon.

  • Okay, so you implant a small wireless device in the connector of a USB cable. No problem - it doesn't take a genius to realize that is a trivial engineering task in this day and age. So now you have a cable that still must work as a cable connecting the computer to whatever USB device is on the other end (printer?), because obviously if the device doesn't work as normal the cable will be replaced. So the secret interface in the cable can't be an actual USB network device. Nor can it even be a USB drive. In

      Its the "bus" and way back into the computer hardware. Not all electronics is a one way 'push' of data down to a port, printer. Some of the end user "interfaces" are nice and complex and can really talk back up into the OS, CPU, wireless hardware.

    The bigger question is - what's a good bug detector nowadays! The sub-$100 are worthless, and the over $1k models - who can really tell what's good and what's not?

  • This cat wasn't going to stay in the bag very long.

    For all of the folks screaming on about this revelation being damaging to national security, I would recommend a 10 minute introductory read on RF. There really is no hiding RF transmissions, particularly when you're trying to transmit through buildings and over long distances. Even with FHSS, random burst, or other masking techniques, RF is easily detected with widely available equipment. Any foreign rival with a modicum of competence has already disc
  • To reach a distance of 8 miles one would have to be transmitting a significant amount of power - probably in the range of several watts. From that, a lot of heat would be generated, and it would be unlikely to go unnoticed.

    Assuming that the usb cables were used as antennae, it is also likely that the radiation pattern is for shit, so I find the claim of an 8 mile range to be highly suspect, absent an extremely high gain receiver antenna and a clear line of sight.

    Nevermind the 500mA USB limit on *most* lapto

      The first hop might be low powered, e.g. out of the building, later local small devices might boost, store, use common background wireless methods to send the data on.

  • How do you make a radio signal hidden of covert? Yes, some spread spectrum techniques make it appear to be just noise, but even so if you sweep in the near field you should be able to detect that something is going on. This might work for soft targets, but for any really secure location it should be detectable pretty easily.

    Forty years ago I worked in a secure facility that was subject to random TEMPEST sweeps at frequent intervals. Even though I was never told what they were doing one look at the equi
  • So, this article is saying that the NSA has hardware that must be physically installed or connected to a computer that allows them to interact with said computer 8 miles away? What's the big deal with that? There is a whole host of things I can do if you let me have physical access to your computer.

    Seriously, I don't see an issue here, nor do I see anything ground breaking. Yes, wireless devices are getting smaller and smaller, I've seen extremely small blue tooth adapters, WiFi adapters and even key logg

    NO, in ALL cases this radio must be inserted. Honestly if you are a tech journalist and dont know crap about technology, please quit and go flip burgers. I am so tired of these "journalists" that colleges are pumping out.
