Security researcher has developed a cheap USB wall charger that is capable to eavesdrop on almost any Microsoft wireless keyboard.
 
MySpace mischief-maker Samy Kamkar has released a super-creepy keystroke logger for Microsoft wireless keyboards cunningly hidden in what appears to be a rather cheap, but functioning USB wall charger.
 
 

The stealthy Arduino-based device, dubbed "KeySweeper", looks and functions just like a generic USB mobile charger, but actually sniffs, decrypts, logs, and reports back all keystrokes from a Microsoft wireless keyboard.
"KeySweeper is a stealthy Ardunio-based device camouflaged as a wall charger that wirelessly sniffs, decrypts, logs and reports-back all keystrokes from any Microsoft wireless keyboard in the vicinity," Kamkar said.
The security researcher has also released instructions on how to build the USB wall charger online and surprisinglyits is cheap to build and quite capable. KeySweeper includes a web-based tool for live keystroke monitoring, capable to send SMS alerts for typed keystrokes, usernames, or URLs, and even continues to work after it is unplugged because of its rechargeable built-in battery.

And being 'wireless' oddly not one single word on it's alleged operating range. Vicinity is a very broad term.

What's this for? I don't think many people use wireless keyboards...

I know more people with wireless than wired.

Another good lesson on why over short ranges a plain old cable is the best way to connect things, why replace a technology that was quite capable of what was needed with one which doesn't really give any significant benefits but does give more potential problmes including (as shown by this) security problems.
Back on this site, for a while anyway, been so busy the last year.

My systems:2 laptops, intel i3 processors, windows 8.1 installed on the hard-drive and linux mint 17.3 MATE installed to USB

When it comes to receiving RF signals, better antennas and amplifiers go a long way to boost the range significantly. But of course, they will not fit in Samy's device.

 

For example, I have a small WiFi Yagi antenna. That's a directional antenna. It easily doubles the range when I point it in the direction of an access point.

Because a cable is not always an option. Do you want a cable running from your keyboard to your smart TV?
