Proof-of-Concept Exploit Development ← uses 90% 1e evidence

The PoC used debug mode MMIO injection via nrfjprog to inject values into UICR.

nrfjprog uses → 95% 1e evidence

Debug mode MMIO injection is performed using the nrfjprog utility.

UICR uses → 90% 1e evidence

Debug mode MMIO injection targets the UICR memory region.
