GFCI's (Ground Fault Circuit Interrupts) are a practically unnoticeable part of our daily lives, except maybe for when you have to fumble around with the Reset button on your hair dryer to get it to work, of course.

I discovered a way to completely melt (magic smoke demo included!) the GFCI mechanism for several off-the-shelf electro domestics wirelessly using specific RF frequencies. Similarly, I'm able to trip other GFCI's (the type built-in to several apartment/home walls) creating a DoS on running electro domestics.

Electro domestics might not be the worst this vulnerability has to offer, since GFCI's are used on many different types of electronics.

I plan on building a directional antenna to hopefully perform remote electro domestic DoS. I will list all vulnerable patents, my discovered vulnerable products, all applicable frequencies, and all affected switch types (such as AFCI's). I also commit to do responsible disclosure of any sensitive electrical attacks, such as RF interference for equipment upon which people's lives or livelihoods may depend.
