Oven Repair (The Hardware Hacking Way)

Discover innovative hardware hacking techniques to repair and modify ovens, including firmware reverse engineering, fault injection, power analysis, and clock glitching, to unlock new possibilities in appliance modification and repair.

Key takeaways

Reverse engineering an oven’s firmware can help repair technicians fix issues without replacing boards.
Fault injection and power analysis techniques can be used to extract information from the firmware.
The oven’s temperature sensor can be calibrated using glitches in the microcontroller’s clock signal.
The oven’s heating element is controlled entirely by firmware, which can be modified to hack the device.
Power analysis can be used to recover secrets from the device, such as passwords or encryption keys.
A Raspberry Pi Pico can be used to generate high-voltage pulses for glitching the microcontroller.
Clock glitching can be used to manipulate the microcontroller’s pipeline and extract information from it.
The oven’s second-stage bootloader can be bypassed using password injection.
The device’s pipeline can be manipulated to extract information from it.
Glitching the microcontroller’s pipeline can be used to delete or modify functionality.
The checksum of the firmware can be corrupted by glitching the microcontroller.
The firmware can be modified to make the oven more reliable and efficient.
The technique of “clock glitching” involves manipulating the microcontroller’s clock signal to cause errors in the device’s processing.
The “fault injection” technique involves intentionally introducing errors into the device’s processing to extract information.
Python and Excel can be used to analyze the power consumption patterns of the device and extract information.
The oven’s firmware can be modified to make it more user-friendly and efficient.
The technique of “power analysis” involves analyzing the power consumption patterns of the device to extract information.
