Sniffing and Decoding NRF24L01+ and Bluetooth LE Packets For Under $30 46
An anonymous reader writes "I was able to decode NRF24L01+ and Bluetooth Low Energy protocols using RTL-SDR. As far as I can see, this is the first time NRF24L01+ is being decoded, especially considering the low entry price for the hardware. Given the extreme popularity of this transceiver, we are likely to see a wave of hackers attacking the security of many wireless gadgets, and they are likely to succeed as security is usually the last priority for hardware designers of such cheap gadgets. A lot of work has been done to decode bluetooth using dedicated hardware, and I am sure this software can be adapted to output the right format as input to existing Bluetooth decoders such as Wireshark."

Who needs a keylogger when you can just pipe their output to your local machine directly?

Good wireless keyboards and mice encrypt the data. Microsoft hardware does this, and I believe that at least some of it also uses Nordic chips.
This isn't really a security vulnerability at all. It's like trying to argue that ethernet is insecure. It's a transport layer, the security comes higher up the chain at the application level. Individual devices may fail to do this, but the author of the blog post made no attempt to determine how many of the devices he claims he could see fit into this category.
