A new and custom firmware for the popular Flipper Zero multi-tool device is reportedly capable of bypassing the rolling code security systems used in most modern vehicles, potentially putting millions of cars at risk of theft. Demonstrations by the YouTube channel “Talking Sasquach” reveal that the firmware, said to be circulating on the dark web, […] The post Flipper Zero ‘DarkWeb’ Firmware Bypasses Rolling Code Security on Major Vehicle Brands appeared first on Cyber Security News.
Why would a firmware be needed? Why couldn’t this just be an application?
Because the flipper doesn’t run applications in the way q smartphone does. If you’re a bit into hardware tinkering: Think of it more like an Arduino than a pi.
I have a flipper. I still don’t understand why this could not be an app.
What feature exists in this firmware that does not exist in the standard flipper firmware?
The new firmware expands the band range of the device.
By default it’s limited to prevent this.
So do unleashed, momentum, etc. Only the OFW locks regions. But momentum and unleashed still struggle with rolling codes (though have more functionality with it than OFW).
Yes.
The flipper tries hard to stay “legal”, respecting all kind of frequency limits - just like you need to use a different firmware for your wifi AP if you want to go beyond legal frequencies for your network.
Without knowing how it works, my best guess is that the micro controller and the radio chip are separate so they are flashing the radio controller and not the main part. I did that with my sonoff 433mhz gateway. I installed Tasmota but the codes it could read were limited. I then flashed the 433mhz radio chip with a different firmware which can read all raw codes on that frequency.
