The attackers claim to have exfiltrated 2 to 3 TB of data, which Reuters verified includes sensitive psychiatric and medical evaluation records. The breach occurred via an unpatched Oracle PeopleSoft zero-day vulnerability (CVE-2026-35273) with a CVSS score of 9.8. ShinyHunters stated the attack was a retaliatory "marketing initiative" in response to a May FBI report that made false allegations about the group's tactics.
