Summercon 2013: Hacking the Withings WS-30

This past weekend I presented Weighing in on Issues with “Cloud Scale” at Summercon 2013 (the title is totally a joke, btw). In the presentation, I talked about my experience reverse engineering and hacking the Withings WS-30 WiFi-enabled bathroom scale, a fun little embedded device running Thumb-2 code.

As mentioned during the talk, I’ve uploaded my slides, tools, and notes for download.  All of the tools I showed in the talk are fairly polished and ready for use in other projects.  There are also a good number of random crappy scripts that I used in one-off scenarios during the project but still may prove useful in some way.

I’ve included a copy of the WS-30 firmware (version 211) in the repo, as well as a copy with no header.  I’m also publishing my .idb so it may help others if they want to look at the code.  I’ve been annotating it for a number of months now so it should be fairly thorough.

If you have any feedback about the presentation or the project itself, let me know!
