DEF CON 29: Why does my camera scream like a banshee? Signal Analysis & RE
I'll be presenting at DEF CON 29 tomorrow on signal analysis and reverse engineering a strange audio encoding used to configure certain models of wireless security camera. Along with the presentation I've created a tool that lets you pair the camera to your wireless network without using the included vendor app. This streamlines the process to speed further reverse engineering work: https://github.com/7thzero/THAMYRIS
Pre-recorded video can be found here: Why does my security camera scream like a banshee?
There are more secrets to uncover in the camera, if time permits. If I had spent just 10 more dollars on a better camera I probably wouldn't be speaking this year as it would have ‘just worked’. See the github repo listed above for more information about the state of camera analysis.
