AutoPRAC: Automating Attack Discovery for PRAC-Based Rowhammer Defenses Using Model Checkers

Per-Row Activation Counting PRAC in DDR5 is a specification to mitigate Rowhammer attacks by tracking activations per row and triggering mitigative refreshes when needed. However, the security of PRAC designs is currently evaluated using human-crafted attack patterns and we lack formal verificati...
