A lot of smart key cars are vulnerable to relay attacks. It's not a solved security issue by any means.
Nobody is fucking doing that, though! This isn’t a “oh I will hack this person using a relay attack” attack, it’s some dumb kids breaking into cars using physical measures. They are NOT going to be using a RELAY ATTACK
Challenge Accepted
They are. It’s not incredibly common, but it’s not rare.
My coworker had his car stolen from his driveway. He believes it was a relay attack.
That being said, it’s super easy to mitigate by putting your keys in a metal bin.
Yes they are, because keyless listens to the car asking for authorization, so you can amplify the car signal hoping the key is not too far off, and unlock the car without any other work.
What’s more, all keyless cars still have a fob with proximity and if the fob dies, they legally have to have a way to start the car without the fob battery which is why they all have an nfc reader somewhere (usually in a cup holder) so you can put you dead fob on it and the car will start like normal.
All keyless start kias and hyundais are/were immune to the Kia boys trick
No engine immobilizer was the ultimate issue. And from what I understand, it was just an issue with models sold in the US, so all this misery was caused by a manufacturer’s cost saving measure.
ETA: To clarify, the cause was a manufacturer’s cost saving measure enabled by the US regulations’ lack of a requirement for engine immobilizers.
Still, it would be cool if they didn't charge hundreds of dollars for a replacement key that costs them a couple bucks.
Til someone uses flipper to clone your key n jack your shit
That’s..not how rolling codes and tight timing requirements work. There are almost zero keyless entry car models that can be unlocked, let alone started, with hardware at the sophistication level of a flipper.
Yeah I did a little homework after I made the comment n realized I was wrong. Didn't get a chance to go back n remove or fix it.
I mainly pushed back because the Flipper Zero is an amazing toy to teach novices young and old about the basics of radios, computing, and cryptography. But they are facing backlash around the world from uneducated, reactionary, “think of the children” mouth breathers and you shouldn’t give those chucklefucks any more ammo in their misinformation belt.
You’re an insane person if you think KIA BOIZ are using a fucking flipper and not opportunistically attacking parked cars hahahaha
