A few weeks back we posted about some slides from the Defcon conference by information security researcher Melissa Elliot which detailed how she used an RTL-SDR to explore the world of unintended radio emissions.
The talk to go with the slides is now available on YouTube
Melissa Elliot (0xABAD1DEA), an infosec security researcher has uploaded slides on the topic of investigating unintentional radio emissions from various electronic devices, and the security issues these emissions can cause. She used the RTL-SDR as the radio receiver to show that sophisticated equipment isn’t needed. One interesting experiment she performed was trying to recover a checkerboard image displayed on an LCD screen entirely via its unintentional radio emissions received with the RTL-SDR. She got close, as you can sort of make out the checkerboard pattern on the recovered image below. Update: Tomsguide have written an article on Melissa’s talk.
