ShinyHunters claims it exploited a critical Oracle PeopleSoft zero-day to compromise more than 100 organizations, including the University of Nottingham, where it says it stole 40GB of student and billing data. "ShinyHunters posted the UK university on its data leak site on Tuesday before publishing the stolen files later that same day, presumably because the school refused to pay the extortion demand," reports The Register. From the report: "University of Nottingham on our leak site is one of the first publicly confirmed incidents," a ShinyHunters spokesperson told us. "We have only just started outreach to affected orgs and are actively looking to reach an agreement with affected orgs." They didn't say when they planned to post the other 100 or so claimed victims. A Google threat intelligence report published Thursday afternoon corroborated ShinyHunters' claims to have compromised more than 100 organizations. Google said it spotted malicious activity, "consistent with the exploitation of CVE-2026-35273," between May 27 and June 9, and notified more than 100 global orgs "whose IP addresses correlated with potentially vulnerable endpoints." Most of these, we're told, are based in the US and 68 percent are in the higher-education sector. Oracle has released a "patch availability document," but it's unclear whether a patch is currently available.

One of the world’s most active ransomware groups exploited a critical vulnerability in Oracle’s PeopleSoft software suite and used it to target about 100 customers and extort at least one of them to pay up in exchange for not leaking stolen data, researchers said.

The group, tracked as ShinyHunters, had been exploiting the PeopleSoft vulnerability for more than two weeks before Oracle flagged it. CVE-2026-35273, as the vulnerability is tracked, carries a severity rating of 9.8 out of 10, making the former zero-day one of the year’s most critical vulnerabilities to be exploited.

Google’s Mandiant security team said it’s an SSRF (server-side request forgery), a vulnerability that allows attackers to send requests from a susceptible server to systems used by the targeted organization. Oracle said the SSRF is remotely exploitable, and the company has issued a stopgap mitigation but has yet to fully patch the flaw. Google has confirmed that victims are receiving extortion demands.
