The 'USB Killer' Has Been Mass Produced -- Available Online For About $50 (arstechnica.com) 243

New submitter npslider writes: The "USB Killer," a USB stick that fries almost everything that it is plugged into, has been mass produced -- available online for about $50. Ars Technica first wrote about this diabolical device that looks like a fairly humdrum memory stick a year ago. From the report: "The USB Killer is shockingly simple in its operation. As soon as you plug it in, a DC-to-DC converter starts drawing power from the host system and storing electricity in its bank of capacitors (the square-shaped components). When the capacitors reach a potential of -220V, the device dumps all of that electricity into the USB data lines, most likely frying whatever is on the other end. If the host doesn't just roll over and die, the USB stick does the charge-discharge process again and again until it sizzles. Since the USB Killer has gone on sale, it has been used to fry laptops (including an old ThinkPad and a brand new MacBook Pro), an Xbox One, the new Google Pixel phone, and some cars (infotainment units, rather than whole cars... for now). Notably, some devices fare better than others, and there's a range of possible outcomes -- the USB Killer doesn't just nuke everything completely." You can watch a video of EverythingApplePro using the USB Killer to fry a variety of electronic devices. It looks like the only real defense from the USB Killer is physically capping your ports.

      Public charging ports don't have data lines... just power. The device would charge but have no data lines for the discharge.

        "Public charging ports don't have data lines"

        Your claim (and that of other's, below) is simply wrong.

        Because, any USB charger expected to work with a wide range of devices does in fact have connections to the USB data pins. If they are unconnected, a USB device can draw no more "one unit load" (0.1 A) from the port. If the data lines are actively used, a device can negotiate to 500 mA. Using the USB charging spec, the data pins are shorted together or with a 200 ohm resistor (depends on the version of the spec), and a device it can draw up to 1.5 A. But that's still unlikely to cause problems with other ports.

        What is a concern is that there are lots of proprietary extensions beyond the USB spec. Apple and Qualcomm are two big players in that regard, using the data lines to signal the availability of current and/or voltages more that the USB spec itself allows. Modern "universal" charging ports actively use the USB data lines to identify the device type and then negotiate available power. These types of ports are becoming more common everyday.

        Even if ports are sufficiently isolated so that one of these "killers" couldn't effect other ports, it's possible that they could damage the port they're plugged into, potentially causing it to deliver voltage damaging to other devices. Even though ESD protection is likely provided (just as it is on a computer's USB port), that's meant to handle only low energy situations (high volt/low amps). These killers are designed to accumulate, then deliver a much greater charge than that.

      It would likely do nothing at all. It dumps the charge down the data lines, a charging port shouldn't have any data lines. Now, maybe the data lines ARE connected to something (so the TSA can search every phone that gets plugged in, "for your safety"), in that case maybe blowing the data lines would be a good thing overall.

        You're wrong. A useful USB charging port _must_ have connections to the data lines (see my post, above).

      No problem at all. These do not have data-lines and 220V is not enough to jump any relevant distance. (Don't you love the general stupidity of the vandalist mind-set?)

        I doubt they'd have a hard time stretching it to over something like this. If you have a device who's only purpose is to destroy something and it goes and destroys something, well you are pretty likely to get in trouble for it.

        Remember courts aren't operated by overly literal geeks who think if they can find some explanation, no matter how outlandish or unlikely, it'll be accepted. The law bases a lot around what is reasonable, and around intent. So your attempt at being cute won't work, and you'll be off to jail.

        It also may very well be illegal just to have, or be made illegal if not. There are devices that are outlawed purely because they have no legit use. Many states ban burglary tools, which can include things like the cracked ceramic piece of a spark plug (the aluminum oxide ceramic breaks tempered glass easily). If they catch you and can prove intent, then you are in trouble just for having them with the intent to use them illegally.

        Oh and don't think they have to read your mind or get a confession to prove intent. They usually just have to show that the circumstances surrounding the situation are enough to lead a reasonable person to believe that you were going to commit a crime.

        And a post like this, would count for sure.

      Probably not much would happen. Many of them just put +5V on the power line and leave the data lines floating or tie them together. Sometimes they have various resistor networks to trigger higher charge rates. Depends on the size of the resistors, but my bet is even throwing 100-200V at them isn't going to do much given how little energy a few ceramic caps can hold. You'll exceed the power rating for a bit, and that will quickly drop off as the caps discharge.

      The bigger problem will be USB C chargers and things like Qualcomm Quickcharge, which actually use digital communication on the lines to trigger various non-5V voltages and higher currents. Because they use actual signaling, they're much more prone to damage.

      As the parent said, the sort of antisocial taintsuckers that would do this are why we can't live in a decent society.

      Charge ports don't have data lines.

      The problem with a device like this is it is hard to find a substantial legitimate use for it. Given that, they are likely to be targeted for a lawsuit and they are likely to lose that suit.

      While it is perfectly ok to sell a device that gets used to commit crimes, you generally have to have a legit reason to be selling it and it can't be something that is totally made up that nobody actually believes. So for example while a crowbar can certainly be used to break in to a house to or attack someone, they are also widely used used to get nails out of things and pry stuck objects apart. As an opposed example a number of companies that sell devices to help you cheat on urine tests have gotten in trouble since their devices had no use other than said cheating.

      It is very, very hard to think of a legit use for this and I can't imagine they'll get many legit sales. So it'll probably get them in legal trouble.

      Get one of those "USB powerbank"s.

      They're dirt cheap. If you don't know what they are, they are one or two 16850 LI-ion cells, a mini-USB port, and a USB-A port. The mini-USB port is used to charge the cells in the powerbank, and then you can plug your gadgets into the USB-A port, to charge them later.

      Use the powerbank to suck the power from a public port first, then plug in your devices. The downside is that the whole process takes longer. The upside is that all you're risking is blowing up your powerbank.

    • Can't the same thing be accomplished with a pre-charged capacitor (a battery or something) with an usb port? Send the charge through the data line and blow stuff up. And I'm sure you can get it cheaper than 50 USD.

      So if this is to become a problem, it won't be from this gadget.

    • Nothing much different? I believe a charger is a tiny computer, is there a 4bit or 8bit CPU in there that negotiates current output to the device?

      • Not usually. Later USB specs followed the de-facto industry practice of allowing chargers to just put specific resistors across(?) the data pins to indicate available current. Makes for much less expensive chargers.

  • This device will self destruct in 5 seconds (or however many cycles it takes to get to -220V)

      I'm with you on this one. All someone did was say "Gee, capacitors can hold large charge and dissipate it quickly so it will destroy a circuit whose design spec doesn't call for handling large voltages" and build a small device to do so. BFD. I can build a 120 or 210 power cord with a usb connector, plug it in a to the wall and a usb port; POW sparks fly as well. The "the interface and machines should have been deigned to prevent such an event" is ridiculous since no one expects someone to design a device to deliberate damage the port; and if you did try to do so why stop there? A screwdriver can also physically damage it so doe step spec require it to withstand such an attack? How about if I put my machine in a microwave? Or do we design it in such a way that it performs as intended and the expectation is it will be used in a reasonable manner?

      Some people will no doubt think it's funny to use one on unsuspecting victims and when caught say "It's just a joke" and / or "The machine should have been designed not to let that happen;" and be surprised when they are hauled into court. Oh well, you can fix a fried device but you can't fix stupid.
