We may live in a software world, but all that software runs on hardware at some point down the stack. Sure, you need some hardware to talk to hardware, but that shouldn't be a barrier to entry. The cost of a couple pints is enough to get a device to help you. I'll demonstrate 7 different cases where you can use an FT232H-based board or cable to pull off a hardware hack, including: - Getting a root shell over a UART - Modifying I2C configuration of a device - Sniffing a hardware bus as a Logic Analyzer - Dumping flash off a device for offline analysis - Backdooring firmware and flashing it to a device - Jtag debugger - Replaying custom crafted protocol packet Hopefully you'll come away with the confidence and know-how to tackle a hardware attack of your own.
