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

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.

  2. So much for public charging locations by RCourtney · · Score: 5, Insightful

    Like the fact that you can find a USB port in planes, trains, bars, and various other places where you might need to charge up your phone?

    Yup, not any more.

    It really sucks that some people just like to watch the world burn.

    That is basically what a protection diode is - except they do not use zener diodes. They have one diode connected to ground and one to VCC. If the voltage drops below ground, one diode conducts clamping the voltage to ~-0.7v. If the voltage increases beyond VCC, the other diode conducts and clamps the voltage at VCC+0.7v. This is effective when dissipating a small charge that could potentially be at a high voltage - think ESD. But if you have prolonged current the diode will blow and short.

    So you have a short (blown diode) but you still have a significant amount of energy to dissipate. This results in a large current that will cause the diode to physically explode or possibly blow a trace. USB data lines typically use very thin traces and can not conduct much power. If a trace goes then USB is screwed but the rest of the computer will probably function correctly. If the diode explodes your protection is gone and the high voltage will now cause all sorts of damage.

    He isn't draining anything, he's filling it even fuller with Olympic swimming pools worth of sludge. His Treasury Secretary is plucked straight from, drumroll please, Goldman Sachs. After all that time he spent complaining about the (((GLOBALIST ELITE BANKERS))) and whining about Hillary's speech to Goldman.

    I'm going to enjoy watching his supporters slowly figure out they fell for a long con, got suckered bigly, and voted in the world's yuuuuugest huckster.

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

    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.

    Bingo. The Trumpkins have been completely suckered, as you can see from the resumes of those in President-elect Donald Trump’s closest political circle so far:

    Treasury secretary nominee Steven Mnuchin: Goldman Sachs.

    Chief strategist Steve Bannon: Goldman Sachs.

    Transition adviser Anthony Scaramucci: Goldman Sachs.

    Commerce secretary nominee Wilbur Ross: Rothschild & Co.

    Possible budget director Gary Cohn: Goldman Sachs.

    Potential secretary of state Mitt Romney: Bain Capital.

    And Trump is just getting started. Check out that “swamp draining!" Take that, Wall Street!
