The tech used here is the popular Flipper Zero, an ethical hacker’s swiss army knife, capable of all sorts of things such as WiFi attacks or emulating NFC tags. Now, 404 Media has found an underground trade where much shadier hackers sell extra software and patches for the Flipper Zero to unlock all manner of cars, including models popular in the U.S. The hackers say the tool can be used against Ford, Audi, Volkswagen, Subaru, Hyundai, Kia, and several other brands, including sometimes dozens of specific vehicle models, with no easy fix from car manufacturers.
Fucking real! My car (2016 Toyota Avalon) uses a rolling code for the transponder! It’s like one of the most basic things any manufacturer can do to avoid this shit! And it can’t be more than a few dozen lines of code (I’m no expert so this may be an exaggeration)?
Of course, this particular attack actually “works” with rolling codes (WILL desync your real keyfob), it requires the attacker to sniff one signal off your key (incl lock) and then they can spoof your key’s rollover protocol (and any button, not just the one they sniffed) to reset the rolling code back to 0 and allowing them access. Iirc it’s different from a standard replay attack in (definitely) that it can spoof other keys on the fob it hasn’t read, and (I think) that while a trad replay attack requires the car not to hear the signal when recording I believe that doesn’t matter with this attack.
Unfortunately I haven’t been able to test it out since I’m not buying a serial locked flipper firmware from some guy who just got out of prison selling it on telegram.
What if I only use the fob as a fob? I usually only use the touch pad to lock and inner handle’s proximity sensor to unlock, so the car is only range finding after initial sense.
It is almost like their should be something written down somewhere. Like a guideline or rule or something…
Oh that is right, it is called a regulation requiring basic wireless security for extremely expensive consumer items.
Nope can’t do that.
Won’t someone think of the multi billion dollar corporations‽
