Voltage Glitching for Fun and Profit (MCU Fault Injection)

Why This Post Exists I wanted to learn practical voltage fault injection on low-cost MCUs like WCH CH32V003 and Puya PY32F003 . What is Voltage Glitching? Voltage glitching is a form of hardware fault injection where very short disturbances are introduced into a device's power supply. These disturbances can cause the CPU to skip instructions, misread memory, or bypass security checks. Researchers…
