Anyone in the know about IoT security is likely to steer clear of a physical security product that’s got some sort of wireless control. The list of exploits for such devices is a long, sad statement on security as an afterthought, if at all. So it’s understandable if you think a Bluetooth-enabled lock is best attacked via its wireless stack.
As it turns out, the Master 5440D Bluetooth Key Safe can be defeated in a few minutes with just a screwdriver. The key safe is the type a realtor or AirBnB host would use to allow access to a property’s keys. [Bosnianbill] embarked on an inspection of the $120 unit, looking for weaknesses. When physical attacks with a hammer and spoofing the solenoids with a magnet didn’t pay off, he decided to strip off the resilient skin that Master so thoughtfully provided to prevent the box from marring the finish of a door or gate. The denuded device thus revealed its awful secret: two Phillips screws, each securing a locking shackle to the cover. Once those are loose, a little prying with a screwdriver is all that’s need to get the keys to the kingdom.
In a follow-up video posted later, [Bill] took a closer look at another key safe and found that Master had made an anemic effort to fix this vulnerability with a squirt of epoxy in each screw head. It’s weak, at best, since a tap with a hammer compresses the gunk enough to get a grip on the screw.
We really thought [Bosnianbill]’s attack would be electronic, like that time [Dave Jones] cracked a safe with an oscilloscope. Who’d have thought a screwdriver would be the best way past the wireless stack?

[Plore], a hacker with an interest in safe cracking, read a vehemently anti-smart-gun thread in 2015. With the words “Could you imagine what the guys at DEF CON could do with this?” [Plore] knew what he had to do: hack some smart guns. Watch the video below the break.
Armed with the Armatix IP1, [Plore] started with one of the oldest tricks in the book: an RF relay attack. The Armatix IP1 is designed to fire only when a corresponding watch is nearby, indicating that a trusted individual is the one holding the gun. However, by using a custom-built $20 amplifier to extend the range of the watch, [Plore] is able to fire the gun more than ten feet away, which is more than enough distance to be dangerous and certainly more than the few inches the manufacturers intended.
Not stopping there, [Plore] went to the other extreme, creating what he calls an “electromagnetic compatibility tester” (in other words, a jammer) that jams the signal from the watch, effectively preventing a legitimate gun owner from firing their gun at 10 to 20 feet!
Not one to call it quits, [Plore] realised that the gun prevented illicit firing with a simple metal pin which it moved out of the way once it sensed the watch nearby. However, this metal just happened to be ferrous, and you know what that means: [Plore], with the help of some strong magnets, was able to move the pin without any electrical trickery.
Now, we’ve already covered the many hurdles that smart guns face, and this specific investigation of the state of smart gun technology doesn’t make the picture look any brighter. We’re aware that hindsight is always 20/20, so let us know in the comments how you would fix the problems with the Armatix IP1.

Security researcher [Fran Brown] sent us this tip about his Tastic RFID Thief, which can stealthily snag the information off an RFID card at long range. If you’ve worked with passive RFID before, you know that most readers only work within inches of the card. In [Fran’s] DEFCON talk this summer he calls it the “ass-grabbing method” of trying to get a hidden antenna close enough to a target’s wallet.
His solution takes an off-the-shelf high-powered reader, (such as the HID MaxiProx 5375), and makes it amazingly portable by embedding 12 AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output. When the reader sees a nearby card, the information is parsed through the Nano and the data is both sent to an LCD screen and stored to a .txt file on a removable microSD card for later retrieval.
There are two short videos after the break: a demonstration of the Tastic RFID Thief and a quick look at its guts. If you’re considering reproducing this tool and you’re picking your jaw off the floor over the price of the reader, you can always try building your own…

Once [Ruan] over at AndroidClone heard that Android devices were capable of running a full Linux environment, he started contemplating all of the things he might be able to do with a full Linux OS in his pocket.
He decided that a portable penetration testing platform would be great to have on hand, so he got busy installing Ubuntu 10.10 on his Lenovo LePhone. Once he had it up and running, he stripped out all of the unnecessary fluff and added some common tools such as Wireshark, Nmap, and Kismet, among others. He says it easily runs side by side with Android, allowing you to switch between the Ubuntu install and your standard Android applications with ease.
While this all started out as a proof of concept, he has continued to refine the project, releasing several new versions along the way. If you are interested in giving it a try, he has installation instructions available in the AndroidClone forums.
Inside this box you’ll find a La Fonera wireless access point. [Emeryth] and his band of miscreants built this portable device for WiFi security testing. The AP is running OpenWRT and has been set up to use the 16×4 character display as a terminal. An ATmega88 connects the LCD as well as six buttons to the UART of the La Fonera. From there, a set of Ruby scripts takes care of the communication protocol. As you can see after the break, this setup allows you to scan the area for WiFi, showing channel, SSID, and MAC information. Although not specifically outlined in the video we suspect there’s some more devious tricks up its sleeve too.

The Remote Exploit Development Team has just announced BackTrack 4 Beta. BackTrack is a Linux based LiveCD intended for security testing and we’ve been watching the project since the very early days. They say this new beta is both stable and usable. They’ve moved towards behaving like an actual distribution: it’s based on Debian core, they use Ubuntu software, and they’re running their own BackTrack repositories for future updates. There are a lot of new features, but the one we’re most interested in is the built in Pico card support. You can use the FPGAs to generate rainbow tables and do lookups for things like WPA, GSM, and Bluetooth cracking. BackTrack ISO and VMWare images are available here.
