⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all credentials and secrets stored in the PAM system, enabling lateral movement across the entire network and persistent access to critical systems.
Likely Case
Attackers exfiltrate administrator credentials and session tokens, gaining privileged access to manage and extract sensitive data from the PAM system.
If Mitigated
Limited exposure if network segmentation and strict access controls prevent external access to the PAM interface.
