Perhaps worth pointing out that the attacks require the attacker to position a piece of hardware between the Qi charger and the power source.
Is that piece of hardware a bic lighter
Could be
According to the researchers, “A charger can be manipulated to control voice assistants via inaudible voice commands, damage devices being charged through overcharging or overheating, and bypass Qi-standard specified foreign-object-detection mechanism to damage valuable items exposed to intense magnetic fields.”
So if someone swaps your Qi charger for a malicious one they can ruin your phone (or some other device it’s supposed to detect as not a phone ?) and maybe execute arbitrary voice commands… 🥱
Malicious charger:
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.
Well now all we need is internet connected chargers with dodgy security…
Talk about a burner phone 😎☀️ Aaaaaeeeoooowwww
this is unrelated but that is a really nice diagram
A charger can be manipulated to control voice assistants via inaudible voice commands…
This seems like the scarier attack, to be honest…
Though, surely there’s filtering that can be performed to prevent that as an attack vector
So… Considering necessary access, it’s a quarter step above “cooking a phone in a microwave oven might catch it on fire”, IMO.
