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 re-discovered a way to melt and spark (sometimes explode) components that make up the GFCI mechanism for several off-the-shelf electro domestics wirelessly using specific RF frequencies. Magic smoke/spark demo included! 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 are probably not be the worst this vulnerability could potentially achieve, since GFCI’s and solenoids are used on many different types of electronics and they are required by code on many household locations.I also use a directional antenna to remote disable and/or trip GFCI’s from a few yards away. I list all vulnerable patents I ran across and all affected switch types (such as AFCI’s).
