embedded | Check out this piece from embedded featuring IOActive’s recent research that took place during the Raspberry Pi RP2350 Challenge, where IOActive secured a win for “Extracting antifuse secrets from RP2350 by FIB/PVC.”
… “Among the winners, IOActive stood out for its discovery related to the extraction of antifuse secrets from the RP2350 using focused ion beam (FIB) and passive voltage contrast (PVC) techniques. Antifuses, traditionally considered a high-security memory medium, were thought to be resistant to extraction. …
“The IOActive discovery represents a significant turning point in the field of embedded systems security. What was once considered a highly secure form of memory has now been shown to be vulnerable to relatively accessible and established techniques, raising concerns about the entire ecosystem of devices that use antifuse-based OTP memory.”
