The ShinyHunters extortion crew exploited an unpatched flaw in Oracle PeopleSoft to break into enterprise systems, steal data, and demand payment to keep it private. The campaign hit universities hardest. Google's Mandiant attributes it to the group it tracks as UNC6240, and dates the activity between May 27 and June 9. Oracle did not publish its advisory until June 10, so the bug was a [xlite_meta score:56 src:The Hacker News xlite_fp:968b5598cbf048a4b2d1debfd9c31c9e1f2281ba0abbd9f9207b14505b1e5873]

Oracle is warning about a critical PeopleSoft Suite zero-day vulnerability tracked as CVE-2026-35273 that allows unauthenticated remote code execution, with the flaw actively exploited in ShinyHunter data theft attacks. [...] [xlite_meta score:70 src:BleepingComputer xlite_fp:24410115fcfb868a57cd6d21a3fcfac16d601dd8af8457e6dbff6c58cbc83407]

Introduction Mandiant and Google Threat Intelligence Group (GTIG) have identified an active compromise and extortion campaign attributed to UNC6240 (ShinyHunters) targeting Oracle PeopleSoft application infrastructure. The activity was observed between May 27, 2026, and June 9, 2026 and is consistent with the exploitation of CVE-2026-35273, a critical remote code execution vulnerability (CVSS 9.8) in the Environment Management component. The exploitation of this vulnerability directly aligns with the observed targeting of Environment Management Hub (PSEMHUB) endpoints. Because this activity predates Oracle's June 10, 2026 advisory, the vulnerability was exploited as a zero-day. Upon becoming aware of active scanning and exploitation, we initiated notifications to over 100 global organizations whose IP addresses correlated with potentially vulnerable endpoints. Most of these organizations were based in the United States, and 68 percent operated within the higher education sector. Subseq
