Those badges are supposed to do a cryptographic handshake with the reader so that you can't just clone them.
So are car keys, for that matter.
The problem is that the cryptographic handshake proves identity but does *not* prove *proximity*. Attackers can't clone the key/badge but they can boost the signal to confuse the reader into thinking the key/badge is nearby when it's actually not.
I don't know how feasible such an attack is with badges, but cars were stolen.
@argv_minus_one @Viss @funnymonkey if only I was smarter this would be interesting to investigate... But alas I'm a idiot loser so it will end up being a mental experiment

@argv_minus_one @funnymonkey this hack happens outside of pairing
@Viss @argv_minus_one @funnymonkey this part involves pairing, no?

Yes but they can't impersonate the headphone to the phone if the headphone isn't paired to the phone, can they?

@da_667 @winterknight1337 i wish other folks were into arc raiders. cruising around in a team of 3 would be so rad

@da_667 @winterknight1337 its a sneakmode one tho

@Viss @da_667 @winterknight1337 I've been eyeing it for a while, especially since it appears to not be outright hostile to Linux.
But I'm also using an old enough NVIDIA card to be affected by the recent Arch kernel/driver shenanigans π

@da_667 @winterknight1337 you can go full 100% stealth if you want, or you can go picking fights, or you can snipe from halfway across the map. i turned on that thing in steam where friends can watch me stream if im playing, if you wanna creep on me
