Armis, an Internet of Things (IoT) security vendor and cyber-security firm, reports that about half a billion smart devices being used around the globe are vulnerable to a decade-old attack called DNS rebinding. It is the same firm that previo… Continue reading DNS rebinding attack puts half a billion IoT devices at risk
For several years now, a more energy-efficient version of Bluetooth has been available for use in certain wireless applications, although it hasn’t always been straightforward to use. Luckily now there’s a development platform for Bluetooth Low Energy (BLE) from Texas Instruments that makes using this protocol much easier, as [Markel] demonstrates with a homebrew video game controller.
The core of the project is of course the TI Launchpad with the BLE package, which uses a 32-bit ARM microcontroller running at 48 MHz. For this project, [Markel] also uses an Educational BoosterPack MKII, another TI device which resembles an NES controller. …read more
[KaZjjW] wanted to retrofit a pair of nicely styled vintage headphones to be able to play wirelessly over Bluetooth. In principle this is an easy task: simply stick a Bluetooth audio receiver on the line-in, add a battery, and you’re all set. However, [KaZjjW] wanted to keep the aesthetic changes to the headphones at an absolute minimum, retaining the existing casing and volume control, whilst cramming the electronics entirely inside and out of sight.
With the inherent space constraints inside the cups of the headphones, this proved to be quite a challenge. The existing volume potentiometer which hung half outside …read more

How is an unknown bluetooth device connecting to my laptop with my computer in airplane mode? I have a VPN on & use glasswire firewall. I cannot see who it (device) is & can’t seem to stop connection.

[Calango] is a railway technician, and for a school final project created the Rail Wear Surveillance Trolley (RWST) which is a delightfully designed device made mainly from PVC conduit with one job: travel down a segment of train track while shining a green laser onto the rail, and capture camera images. The trolley holds both the laser and the camera at just the right angles for the camera to capture a profile of the rail’s curved surface. The images are sent via Bluetooth to a smartphone for later analysis. Rail wear can be judged by checking how well the profile …read more
The BLE data is encrypted using AES-CCM. the TLS1.3 removed AES-CCM from the cipher-suits due to security issue.
My question :
why don’t they encrypt the BLE using chacha20-poly1205 ? is it because there is no hardware supp… Continue reading Bluetooth low energy encryption using chacha20-poly1305
We’re beginning to think the “S” in [Jeremy S Cook] stands for strandbeest. He’ll be the talk of the 4th of July picnic once he brings out his latest build—a weaponized, remote-controlled strandbeest that shoots bottle rockets. There are a bank of money shots up on Imgur.
This ‘beest is the natural next step after his remote-controlled walker, which we featured a month or so ago. Like that one, the locomotion comes from a pair of micro gear motors that are controlled by an Arduino Nano over Bluetooth. The pyrotechnics begin when nitinol wire cleverly strung across two lever nuts …read more

Surely our readers are well aware of all the downsides of owning an airplane. Certainly the cost of fuel is a big one. Birds are a problem, probably. That bill from the traveling propeller sharpener is a killer too…right? Alright fine, we admit it, nobody here at Hackaday owns an airplane. But probably neither do most of you; so don’t look so smug, pal.
But if you did own a plane, or at least work at a small airport, you’d know that moving the things around on the ground is kind of a hassle. Smaller planes can be pulled by …read more

Tapplock sells an "unbreakable" Internet-connected lock that you can open with your fingerprint. It turns out that: The lock broadcasts its Bluetooth MAC address in the clear, and you can calculate the unlock key from it. Any Tapplock account an unlock every lock. You can open the lock with a screwdriver. Regarding the third flaw, the manufacturer has responded that… Continue reading Ridiculously Insecure Smart Lock
What features should a Bluetooth adapter have for hacking? This could range from a long antenna to a specific chip model number that is known to work.
To make things simple – I do not want to waste £100 on a Bluetooth adapte… Continue reading What features should a Bluetooth adapter have for hacking?
