VEX Cortex Wireless Attacks in Hacks & Mods Posted November 7, 2017 Okay, I was looking at this attack more, first I fired up a wireshark, and listened while I turned on on off the robot, pair and disconnected them, and sent controls. I was able to find lots of garbled packets, things that were kinda regular with off/on actions, I was doing this at school where the network situation is terrible, there was a lot of background noise, and it was hard to find what was VEX and what was not. When we were at competition our robot did end up disconnecting during the match, and they just said too bad, you do not get any points this round because the protocol is bad, and that took up from 3rd place to 5th and top 4 advance. We think this is because interference with other robots, with like 20 teams they started disconnecting, this makes me think they may only have one mac address just on different channels or subsets? this makes me think a deauth attack would work, and I will look into packet attacks, man in the middle attacks, arp DoS, deauth DoS, and hopefully the take another robot/replay attacks!
