Is this simply a USB keyboard or does it exploit some vulnerability to access the host device?
The cool thing is how small it is, and it having wifi.
I have seen this guy showing some of his stuff off before on hak5's youtube.
Would be interesting to see if it could be put into a mouse USB, with passthrough so the user can use the mouse as normal. But I guess you could just stick it inside the mouse casing...as long as somebody doesn't inspect the insides of the mouse.
