Glitching point

1

Hi,

I am working on a voltage glitch insertion attack on the STM32F0 microcontroller. I am analyzing the board, looking for a power point where to insert the glitch and I have seen that in the article (Replicant: Reproducing a Fault Injection Attack on the Trezor One) the STM32F4 has a similar scheme. I have the problem that there is no VCAP line. Do you think that if I make my attack on the VDD line, will the regulator prevent me from inserting the glitch?

Hello ! Any update on this ?

I’ve also found that once you get close to the correct glitch window, making very small adjustments and collecting multiple traces helps a lot. Sometimes the successful region is much narrower than expected, so patience and systematic testing can save a lot of time.
