(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.
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.
