Tutorial "Bypassing security firmware for STM32"

Hello for Everyone!
On the conferences I listened that the CW can bypassing firmware security. Does have anyone example or Tutorial? I find Tutorial A9 Bypassing LPC1114 Read Protect, but interisting for me STM32 and CW1200.

don’t know whether there is some tutorial, but you might want to have a look at the recent publication in the TCHES journal with the title “shaping the glitch” .

Thank a lot for the answer.
How I understood from this paper, authors can downgrade Level security, but reading of guarding firmware is still impossible. Doesn’t it?

Hi #NikSha, I am working on similar target stm32f2/f4, do you have successfully glitch?
