Brutal Kangaroo: How CIA Hacked Offline Computers Using Infected USB Drives

Brutal Kangaroo: How CIA Hacked Offline Computers Using Infected USB Drives

Short Bytes: Brutal Kangaroo malware is the latest addition to the ongoing WikiLeaks Vault 7 leaks. Published earlier this week, the leaked documents show how the CIA hacked offline and air-gapped computers using USB drives. Brutal Kangaroo is basically a combination of 4 tools which work together. The malware used Windows operating system vulnerabilities to targeted air-gapped computers. […]

Animated Bathroom Sign

Once upon a time, pants were created. After a while, women were allowed to wear them too. This has made a lot of people happy and been widely regarded as a good thing. There is a problem, however – bathroom signage is largely predicated on the idea that there are two rigid genders which all humans must be sorted into, and they’re defined by whether you’re wearing pants or a dress. [Robb Godshaw], among others, disagrees with this, and set about building a gender fluid bathroom sign.

The sign assembled on the motor.
The project seeks to exploit the traditional symbols of “male” and “female” – the human figures wearing pants or a dress – by creating a sign that switches between the two every 15 seconds. This is likely to initially confuse – one might imagine the bathroom is actually changing its gender designation rapidly, forcing users to complete their business in an incredibly short timeframe. However, the message behind the project is to highlight the absurdity of defining gender by pants, colours, or indeed in a binary nature at all. [Robb] also helpfully points out that all humans have to pass waste, regardless of gender.

The sign is built with 3D-printed components, using a crank mechanism to actuate the moving parts. The mechanism is designed to give equal time to the pants and dress configurations. [Robb] shares the important details necessary to replicate the build, such as how to assemble the metal crank pin insert with a paperclip and a lighter. It’s particularly tidy the way the mechanism is integrated into the parts themselves. In true hacker style, the motor is a standard microwave oven turntable motor, which can be harvested easily from a junk appliance and can be plugged straight into mains power to operate, if you know what you’re doing. If you don’t, check out our primer on the topic.

Overall, the project is a great use of hacker techniques, like 3D printing and harvesting parts, to make a statement and start a conversation, while being fun, to boot. We’ve also seen some of [Robb]’s work before, like this giant hamster wheel for people. Video after the break.

Mineração Ethereum (parte 2) – GPUs para mining, dificuldade exponencial e as incertezas do mercado

Mineração Ethereum (parte 2) – GPUs para mining, dificuldade exponencial e as incertezas do mercado Estão saindo algumas notícias de possíveis GPUs para mineração, tanto da NVIDIA quanto da AMD. Se é apenas um boato ou é realidade, ainda eu não sei. Mas eu sei que a dificuldade de mineração esta aumentando exponencialmente e isso não está sendo levado em consideração por muitos mineradores, especialmente os iniciantes. Uma pequena correção na tradução que eu fiz do primeiro artigo, quando eu falo “tempo do bloqueio”, na verdade a frase block time refere-se ao “tempo dos blocos de mineração”.

Dirty Now Does Cables

PCB makers Dirty made a name for themselves in the prototype PCB biz, with a convenient web form and numerous options for PCB color, thickness, layers, silk screening, and so on. Now they’ve branched out into custom cabling with Dirty Cables.

You can design it yourself by dragging wires and connectors out of a sidebar and arranging them on a workspace, deciding which wire goes to what pin of the connector. Your choices for wires include various gauges and ribbon configurations. You choose a color (they have eleven) select connectors and drag those out too–choose from 17 cable-to-cable and cable-to-board connector families. We made a quick cable with four 32ga wires and two 16ga wires, with two different connectors on each side, with pricing updated realtime. If you want a sample pack of connectors, Dirty sells them for $10.

The downside to the service: there’s a minimum order of 100, though paying Shenzhen prices might make it worth your while. Just imagining crimping all of those connectors makes Hackaday’s hands hurt.

To get a sense of the diversity of connectors out there, read Elliot’s piece on the connector zoo that we published last year.

Fired Employee Hacks and Shuts Down Smart Water Readers in Five US Cities

A Pennsylvania judge has sentenced Adam Flanagan, 42, of Bala Cynwyd, PA to one year and one day in prison for hacking and damaging the IT networks of several water utility providers across the US East Coast. The sentence was passed down last week for crimes committed in the spring of 2014. […]

I love the GPD XD and the GPD Win that I reviewed earlier (you can find those reviews linked above). This one offers similar performance to the GPD Win (with its X7 Cherry Trail processor) and exceptional build quality. The entire device is clad in aluminum. Surprisingly I didn’t hate the tiny keyboard on it. Usually these small keyboards don’t work well for me but I found myself typing on it better than I expected. It won’t be nearly as good as a full size keyboard but it is more useful than I anticipated. I paid $399 for it during their very successful Indiegogo campaign. I think that’s a fair price for what this is. The selling price of $599 is a bit steep given the performance. While GPD says this is compatible with Ubuntu I was unable to get it to work properly on my device. I will follow up with them and post a Linux video a little later once it is worked out.

Listen to your Body

[John Miller] has the perfect response next time he complains about an ache or pain and one of his friends says, “You should listen to your body!” As you can see in the video below, he already does. Using two 9V batteries and some instrumentation amplifiers, [John] built an electromyography (EMG) rig.

If you haven’t heard of EMG, think of EEG or EKG, but for muscles instead of your brain or your heart. The LT1167 amplifier is well-suited for this application and even has a data sheet showing how to create an EMG circuit. [John] also used some more garden-variety op amps and the ubiquitous LM386N chip for audio amplification.

This isn’t the first EMG rig we’ve seen, but [John] does a nice job of explaining why such a special amplifier is used and how it works. He also provides a lot of pointers to more detailed information, including a paper that covers the safety aspects of hooking yourself — or anyone — up to electronics.

The op amps require a dual polarity power supply, so the project uses two 9V batteries. Not only is this handy, but it eliminates any concerns about the device that connects to you getting power from the wall.

Why do you want to listen to muscles? Maybe just to do it, which is a perfectly good excuse around here. However, it is possible to use the signals to control devices like prosthetic limbs, cursors, and more. You can even move someone else’s arm with the right equipment.

We’ve covered an open source muscle interface as part of our Hackaday prizes. Our own [Bil Herd] has even used himself as a guinea pig.
