A team of security experts at the University of Florida working with security audit company CertiK has found that a certain class of cyberattacks could cause a smartphone to catch fire via its wireless charger. The team has posted a paper describing their research and results on the arXiv preprint server.
I don’t really get how they consider this a meaningful attack vector at all. Of course I can set the phone on fire if I can replace the charger - that’s pretty much always going to be true and there’s no reasonable way to fix it. The only possible use I see is to do it when someone is not intentionally charging their phone, e.g. holding a malicious charger close enough when they have the phone in their pocket.
