⚠️ Risk & Real-World Impact
Worst Case
An attacker with physical access could compromise cryptographic keys or internal communications, potentially gaining unauthorized access to sensitive systems or data.
Likely Case
Limited impact due to physical access requirement; most likely scenario involves targeted attacks against specific physical devices to intercept or manipulate communications.
If Mitigated
With proper physical security controls and network segmentation, impact is minimal as the attack vector requires direct physical access to vulnerable devices.
🎯 Exploit Status
Exploitation requires physical access to devices and understanding of the PRNG implementation.
