There are lots of great tools out there for Software Defined Radios (SDRs). GNURadio. Universal Radio Hacker. So many more. BUT, did you ever wonder how these tools actually turn radio signals into digital data? The Ones and Zeros that we want to see? In my new video series, I'm pulling back the curtain on demodulation, the process of turning a radio signal into a digital one. We are going to use libuhd and write our own C++ code to do all the work. no shortcuts. no library calls for demod. Part 1: On-Off Keying

Found this TINY flash chip on the DistrictCon conference badge and just had to remove it and dump the firmware 🤣 First time using my USON8 2x3 adapter

Found a simple vulnerability the other day in a Chinese IoT camera. SSL communications were going out to a cloud server without validating the server certificates. This led us to be able to perform a man-in-the-middle attack and intercept the SSL communications.

Ever wonder how LTE-based IoT devices communicate over the internet? I modified a Chinese GPS tracker that is in common use in the US and got the cell modem to communicate with internet systems other than the GPS tracker's cloud servers.

I'm excited to announce the launch of my first training course: Digital Signal Analysis for Hardware Hackers! Check it out: Here is a bit of a preview into some of the things we do with logic analyzers in the training!
