Security researchers on Friday unveiled an open-source device that captures the traffic of a wide variety of wireless devices, including keyboards, medical devices, and remote controls.

Keykeriki version 2 captures the entire data stream sent between wireless devices using a popular series of chips made by Norway-based Nordic Semiconductor. That includes the device addresses and the raw payload being sent between them. The open-source package was developed by researchers of Switzerland-based Dreamlab Technologies and includes complete software, firmware, and schematics for building the $100 sniffer.

Doesn't surprise me that something like this exists. I wonder how far a wireless keyboard's signal goes before it is unusable in this sort of attack. If I had to guess, I'd say the attacker would have to be within 50ft of you to do any damage.

Sniffers have been around for a while, there are rumors the spooks have some good to 300 feet, but those have been rather expense in the past. This kit and schematics for $100 means the kid next door might build one like we (older guys) used to do with Erector Sets or Heathkit gear. Because we could.

bluetooth stuff is really easy too, and that signal travels a good distance.

I've never liked wireless keyboards or mice because the fact they take BATTERIES and I really hate replacing batteries in stuff.

I'll stick with wires, no batteries, and safer!

Xor is not a very proper way to secure data
So, the embassy workers with Tempest shielded screens have been leaking data through their keyboards?
