Silicon Under Attack Physical Exploitation Of Modern Chips
summary
Live fault injection succeeds across three cost tiers: a $100–$1,000 ChipWhisperer bench that achieves exploitable glitches, a mid‑tier EMFI setup using a chip shouter and CNC router platform that yields repeatable faults, and high‑end laser fault injection with risky decapping that still faces lithography and packaging difficulties. All three attacks extract or corrupt secrets on an automotive microcontroller yet none trigger on‑chip alarms; polymorphic self‑destructive registers exist in research but are not shipping.
