One thing I can't figure out from a cursory reading is what type of RF hardware would be needed to use this?
I was just thinking about finding some software like this is because I have lost one of the keyless entry key fobs for our car and I was thinking if I could record and replay the signal from the car, I might be able to narrow down the fob location.
I suspect it is in the house somewhere. But we have a 1 year old who loves to pick things up and insert them into any slot or box he can find.
In order to transmit you need some slightly better hardware, such as the HackRF. Replaying a signal with a HackRF is really easy. Note that technically you're not allowed to transmit without a license, whereas reception is generally lawful, with very few exceptions (looking at your legal scar tissue, UK). The author of HackRF published a nice, though not yet completed, tutorial series on YouTube.
There's a lot of activity in the spectrum, if you like to tinker with things then definitely get an SDR, some of the best entertainment value per dollar for a hacker :)
edit: wow i just saw the lecture video and this seems like a tool that lets you detect/analyze radio frequencies emitted from almost any device (?) and lets you emulate the packets (?) or wave patterns to manipulate the data it sends out?
this seems like a really powerful tool. I wonder if you can open car doors with this. Also wouldn't this mean that this tool could become illegal as a result?
Also, opening car doors isn't as simple as repeating a signal you captured(in general)
That said, capturing the car's question when you press the button on the door, amplifying it in the direction of the nearby fob, and then capturing and amplifying the fob's response would work for some systems.
There are a lot of reports (I’m from Germany) from car brands selling cars in 2022 which can be opened easily by repeating/relaying the keyfob signal. Newer systems which also check the signal delay mitigate this. [1] the German ADAC (German Automobile Club) did a test with 500 cars. I was happy to learn that my new car is save from the simple repeat attack. [1] https://www.adac.de/rund-ums-fahrzeug/ausstattung-technik-zu...
This tool is an advanced front-end for such hardware, kinda like Wireshark is an advanced front-end for a networking controller. It does look pretty cool.
