When you’re at HOPE, of course you’re going to see a few Tor proxies, but [Jose]’s is top-notch. It’s a completely portable Tor proxy (.br, Google translation), battery-powered, with a connection for 4G networks.
[Jose]’s OnionPi setup is based on the Adafruit version, but adds a few interesting features that make it even more useful. It’s battery-powered with about a day of charge time, has a built-in battery charger, Ethernet pass through, external 4G and WiFi antennas, all in a sealed case that makes the entire build impervious to the elements.
While this isn’t much of a hack per se, the amount of integration is impressive. There are switches to turn off each individual networking port, and all the relevant plugs are broken out to the front panel, with the AC input and USB serial connection using screw connectors that are supposedly very popular in Brazil.
[Jose] also brought along a new device that isn’t documented anywhere else on the web. It’s called NNCFA, or Nothing New Crypto For All. Using a Cubieboard, an interesting ARM single board computer with a SATA connector, [Jose] created a device that will mount TrueCrypt volumes on a hard drive and share them via Samba.
The Electronic Frontier Foundation have released an alpha of their own Open Wireless Router Firmware as part of the Open Wireless Movement. This project aims to make it easier to share your wireless network with others, while maintaining security and prioritization of traffic.
We’ve seen a lot of hacks based on alternative router firmware, such as this standalone web radio. The EFF have based their router firmware off of CeroWRT, one of the many open source firmware options out there. At this time, the firmware package only targets the Netgear WNDR3800.
Many routers out there have guest modes, but they are quite limited and often have serious vulnerabilities. If you’re interested in sharing your wireless network, this firmware will help out by letting you share a specified amount of bandwidth. It also aims to have a secure web interface, and secure auto-update using Tor.
The EFF has announced this “pre-alpha hacker release” as a call for hackers who want to join in the fun. Development is happening over on Github, where you’ll find all of the source and issues.
A surprising number of projects here are in some way influenced by the webcomic xkcd, but usually not as directly as this. Comic 350, “Network” is the tale of a very odd stickman who keeps multiple VMs running an unprotected, old version of Windows. Between the VMs, they have virtually every virus and are, effectively, a computer virus aquarium.
Now it’s a real thing, and best of all, it’s open to the Internet for normal humans to view, complete with screencaps of all seven nodes updated every 30 seconds, the ability to view all processes on each node, and anyone on the Internet can upload any file to a node. All the files uploaded to the nodes are executed, so you get to see in real-time what the effects of “1TB_of_porn_this_took_a_while_to_upload.exe” are on node 3.
The idea of a virus aquarium is cool, but this actually gets much, much more interesting when the project metas itself. Every 24 hours, a virus scanner runs on each node. As of right now, all the nodes are clean making this not a virus aquarium, but a script kiddie aquarium. On at least one node, TeamViewer is running but your guess is as good as mine as to how anyone will get that working.

The D-Link DSP-W215 Smart Plug, a wireless home automation device for monitoring and controlling electrical outlets has just been hacked. Even though it isn’t readily available from Amazon or Best Buy yet, the firmware is already up on D-Link’s web site. The very well detailed write-up explains all the steps that led to this exploit creation.
First, the firmware was unpacked to examine the file system contents. It was found that the smart plug doesn’t have a normal web-based interface as users are expected to configure it using D-Link’s Android/iOS app. The apps however, appear to use the Home Network Administration Protocol (HNAP) to talk to the smart plug running a lighthttpd server. A look at the latter’s configuration file revealed the functions that could be called without any authentication. Another revealed that the firmware could accept an unlimited amount of POST request bytes which were copied in a fix length buffer without any performed checks. We’ll let our readers head to the original article to see where the author went from this point.
We’ve talked about a variety of protocols and how to deal with them in the past. Today, [Dan] is working on sniffing vending machine Multidrop Bus. The Multidrop Bus (MDB) protocol is a standard used in vending machines to connect devices such as currency collectors to the host controller.
To connect to the bus, interface hardware is required. [Dan] worked out compliant hardware and connected it to an Arduino. With the device on the bus, [Dan] got to work on an Arduino sketch to parse the MDB data into a human-readable format. With that working, the bus can easily be sniffed over the Arduino’s serial console.
This is just the start of a more involved project. Since this protocol is used to communicate with a vending machine’s currency collector or card reader, being able to communicate it would allow him to implement his own payment methods. The plan is to augment the vending machine he operates at Vancouver Hack Space to accept Bitcoin. We’re looking forward to seeing that project unfold.
You’re likely aware of the protests and demonstrations happening throughout Venezuela over the past few months, and as it has with similar public outcries in recent memory, technology can provide unique affordances to those out on the streets. [Alfredo] sent us this tip to let us know about riotNAS: a portable storage device for photos and videos taken by protesters (translated).
The premise is straightforward: social media is an ally for protesters on the ground in these situations, but phones and cameras are easily recognized and confiscated. riotNAS serves up portable backup storage via a router running OpenWRT and Samba. [Alfredo] then connected some USB memory for external storage and a battery that gives around 4 hours of operating time.
For now he’s put the equipment inside a soft, makeup-looking bag, which keeps it inconspicuous and doesn’t affect the signal. Check out his website for future design plans—including stashing the device inside a hollowed out book—and some sample photos stored on the riotNAS system. If you’re curious what’s going on in Venezuela, hit up the Wikipedia page or visit some of the resources at the bottom of [Alfredo’s] site.
Being able to use one of your old projects to make a new one better can be quite satisfying. [Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network controllable RGB lamp.
The overall result is an amazing color changing lamp that works perfectly. All that is left to do is create a case for it, or integrate it into an existing lamp. This is a great way to use an LED strip that would have otherwise gone to waste. If you can’t find a scanner with a color wand like this one, you can always start with an RGB strip.
