Hello people, I was recently doing some work with those VEX Robotics wireless control robots and I had some ideas about packet sniffing attacks, replay attacks, man in the middle attacks, and de-authentication attacks. The robots use the Vex cortex, which has a wireless adapter through a USB port, it says that is is 2.4 GHz, and another USB wireless adapter is plunged into a controller, like a joystick. My school did a competition with these robots, and it ended last week, now we are doing another thing just as a school, they said we were doing battle bots. When I did some research I hadn't seen anybody do anything like this and I though I would look into it. When I was doing research I found that, the robots don't use any encryption it is end to end, the controllers or create there own network an access point that the robot connects to, the network it creates is hidden it does not broadcast its SSID and has to be pared with the cortex, they are 2.4 GHz, they all have independent channels or mac addresses (many can operate at the same time without interference). The first thing I though of would be a deauth attack, where I would send out deauth frames to disconnect their robot from the controller from the cortex leaving their robot powerless, I was tinging I could do this with Aircrack-ng, put my wireless card into monitor mode with airmon-ng, find the mac address and channel of the robot with airodump-ng, deauth with aireplay-ng. The next attack I though of was if I could intercept packets from the remote to the cortex and either replay them to keep doing an operation or send in my own by finding out what commands correlated to what packets and injecting them while impersonating the robot. I have not done much with packet sniffing/replay/injection if anybody knows anything on how I could do that? or if anybody has done anything with these robots? or if you have any ideas on wireless attacks? I am all ears and I would love help and suggestions, this seems like a really cool project. I would love to hear your thoughts, thank you
