Securing PeopleSoft After ShinyHunters

Executive Summary

The ShinyHunters campaign showed that PeopleSoft risk extends beyond the perimeter. Once inside, attackers can exploit configuration data, credentials, lateral movement, and legitimate application functions to access and export sensitive data. This guide provides a practical framework for assessing exposure and strengthening defenses across six attack phases: initial access, reconnaissance, lateral movement, application-layer data theft, exfiltration, and data exposure. It outlines key attack vectors, remediation steps, and infrastructure or Pathlock controls to help teams improve visibility, restrict access, reduce bulk extraction risk, and limit the impact of compromised accounts.
