Laser, Glitches & Secret Keys - The Dark Art of Fault Injection

What if I told you a flashlight, a voltage spike, or a well-timed glitch could make your device skip its own security checks and hand over secrets? In this short explainer we break down fault injection attacks — what they are, how attackers do them (voltage & clock glitches, lasers, EM pulses, heat), real risks (bypassed auth, dumped crypto keys, broken secure boot), and practical defenses you can design into hardware and firmware. Watch to learn: • Why fault injection isn’t “software hacking” and why it’s terrifyingly effective • The main fault techniques attackers use and where they commonly work (smart cards, embedded devices, consoles) • Practical mitigations you can implement at the design and system levels • A pointer to our hands-on blog about glitching an STM32 Blue Pill (link below) 👇 Links & resources Practical blog: Glitching an STM32 Blue Pill: https://payatu.com/blog/glitching-on-...
