Oracle has patched a critical zero-day vulnerability (CVE-2025-61882) in its **E-Business Suite**, actively exploited by the **Clop hacking group** to steal **personal information of corporate executives** and extort victims. The flaw allows remote exploitation without credentials, enabling mass data theft from thousands of organizations using the suite for **customer data and employee HR files**. Initially, Oracle downplayed the threat, linking extortion emails to older patched vulnerabilities from July. However, the newly discovered zero-day confirms ongoing exploitation since at least **August 2024**, with Clop demanding ransom to prevent leaking stolen data. Google’s Mandiant reported **widespread attacks**, though not all victims have been contacted yet. The breach poses severe risks to **executive privacy, corporate reputation, and operational security**, with potential cascading effects on Oracle’s enterprise clients globally.
