Episode notes
Natural Sounds Mimic Technology
- The Ross Ice Shelf in Antarctica vibrates audibly in the wind, creating unexpected natural sounds.
- These ice vibrations can be mistaken for technological noises or sound effects.
RP2350 Dual-Core Glitch Hack
- The RP2350 microcontroller includes dual ARM and RISC-V cores combined with security features.
- Hackers found a glitch that disables ARM but enables RISC-V, leaking protected memory via the RISC-V core.
Fault Injection as Computer Mutagenesis
- Fault injection glitching a chip parallels site-directed mutagenesis in biology by inducing precise random mutations.
- Most changes cause failure, but some rare faults yield exploitable states.
