Back from the dead and I have scope images with me...

These images were taken with an oscilloscope. The bit stream shown uses a simple protocol to send data over RF. The wide image was made by cut/pasting various ones together. I used the parallax USB scope. While the supported bandwidth seems low, it is quite good at the low rate bit streams used in simple RF devices.




The images are part of the talk I'm doing at CansecWest this evening.

Other Wireless
New Ways to Get Pwned

The talk doesn't cover 802.11 or Bluetooth. Rather the talk focuses on RF devices such as wireless presenters, mice, and a little about keyboards. The attacks are done in hardware by sniffing and injecting communication between chips.
