Oracle Cloud Breach: 6 Million User Data Allegedly Compromised
2025-03-26

Cybersecurity firm BleepingComputer reports a hacker claiming to have breached Oracle Cloud servers, stealing authentication data for 6 million users. Oracle denies a breach, but BleepingComputer has confirmed the validity of data samples from multiple affected companies. The hacker released databases, LDAP data, and over 140,000 allegedly compromised domains. Investigations suggest exploitation of a vulnerability (CVE-2021-35587) in Oracle Fusion Middleware 11g. Despite Oracle's denial, evidence points to a significant security lapse, raising concerns about Oracle Cloud security.
