Collaborate Disseminate
I’ve just been reading this article on proprietary RF protocols vs Bluetooth and it seems to be suggesting that the security through obscurity gained through a proprietary protocol is advantageous over the more well-known Blu… Continue reading Proprietary RF Protocol Security
The holidays bring us many things. Family and friends are a given, as is the grand meal in which we invariably overindulge. It’s a chance for decades old songs and movies to somehow manage to bubble back up to the surface, and occasionally a little goodwill even slips in here or there. But perhaps above all, the holidays are a time for every retailer to stock themselves to the rafters with stuff. Do you need it? No. Do they want it? No. But it’s there on display anyway, and you’re almost certainly going to buy it.
Which is precisely how …read more
Have you ever wished you could see in the RF part of the radio spectrum? While such a skill would probably make it hard to get a good night’s rest, it would at least allow you to instantly see dead spots in your WiFi coverage. Not a bad tradeoff.
Unwilling to go full [Geordi La Forge] to be able to visualize RF, [Ken Kawamoto] built the next best thing – an augmented-reality RF signal strength app for his smartphone. Built to aid in the repositioning of his router in the post-holiday cleanup, the app uses the Android ARCore framework to …read more

Like many other hobbies, astronomy can be pursued on many levels, with equipment costs ranging from the affordable to the – well, astronomical. Thankfully, there are lots of entry-level telescopes on the market, some that even come with mounts that automatically find and track heavenly bodies. Finding a feature is as easy as aligning to a few known stars and looking up the object in the database embedded in the remote.
Few of the affordable mounts are WiFi-accessible, though, which is a gap [Dane Gardner]’s Raspberry Pi interface for Celestron telescopes aims to fill. For the price of a $10 …read more

I would like to know how are files transferred from one device to another while being connected through bluetooth and on which principle it works.

[Jiska Classen] and [Dennis Mantz] created a tool called Internal Blue that aims to be a Swiss-army knife for playing around with Bluetooth at a lower level. The ground for their tool is based in three functions that are common to all Broadcom Bluetooth chipsets: one that lets you read arbitrary memory, on that lets you run it, and one that lets you write it. Well, that was easy. The rest of their work was analyzing this code, and learning how to replace the firmware with their own version. That took them a few months of hard reversing work.
In …read more
Companies, governments, etc. can track Bluetooth and WiFi network scans passively by looking at a same MAC address over space and time (Bluetooth/WiFi Identity tracking in public spaces – How to discover?). Starting in Androi… Continue reading MAC randomization for Bluetooth?
There are lots of home charger vendors. Some of them, such as ABB or GE, are well-known brands, but some smaller companies have to add ‘bells and whistles’ to their products to attract customers. One of the most obvious and popular options in this respect is remote control of the charging process. But from our point of view this sort of improvement can make chargers an easy target for a variety of attacks. Continue reading Remotely controlled EV home chargers – the threats and vulnerabilities
Perhaps it is true that if all you have is a hammer every problem you see looks like a nail. When you think of augmented reality (AR), you usually think of something like the poorly-received Google Glass where your phone or computer overlays imagery in your field of vision. Bose isn’t known for video, though, they are known for audio. So perhaps it isn’t surprising that their upcoming (January 2019) AR sunglasses won’t feature video overlays. Instead, the $200 sunglasses will tell you what you are looking at.
The thing hinges on your device knowing your approximate location and the …read more
