The Clop ransomware group has listed Oracle Corporation on its dark web leak site, claiming to have breached the company's internal systems. The alleged attack exploited a critical zero-day vulnerability, identified as CVE-2025-61882, in Oracle's widely used E-Business Suite (EBS) software. This vulnerability allows for unauthenticated remote code execution, potentially giving attackers complete control over sensitive enterprise resource planning (ERP) data. The same flaw has reportedly been used in a massive supply chain attack, with Clop affiliates exploiting it for months before a patch was released. The group is threatening to release Oracle's financial and personal records unless ransom demands are met. This news coincides with a significant decline in Oracle's stock, which is on track for its worst monthly performance since 2011, though no sources directly link the stock drop to the breach claim.
