Hacking microchips with $7 and two lines of code: a cheaper and easier fault-injection attack. 📟⚡👨🏻💻😵💫🏆
Security researcher Tongren Chen presents a new, simpler way to hack microcontrollers using precise voltage glitching, powered by a Raspberry Pi Pico. The key idea is: don’t fully understand the protocol - just record it and replay it.
The author claims that fault-injection attacks require writing complex hardware drivers to understand and speak a chip’s communication protocol. That requires specific knowledge and experience, is time- and resource-consuming, and is often undocumented. But not anymore.
The proposed approach:
1️⃣ Record real debugger–chip communication
2️⃣ Replay only the critical parts
3️⃣ Use voltage differences across a tiny resistor to separate bidirectional traffic
Quite an interesting approach that makes fault-injection attacks more affordable for security researchers with no prior knowledge or expensive tools. Worth a try, I think :)
