Oracle E-Business Suite Zero-Day Exploited by Clop Ransomware Group

Clop ransomware group exploited a zero-day vulnerability in Oracle E-Business Suite (EBS), tracked as CVE-2025-61882, to compromise major organizations including Schneider Electric, Emerson, Harvard University, and others. The vulnerability allowed unauthenticated remote access to Oracle Concurrent Processing, enabling attackers to exfiltrate large volumes of sensitive data such as ERP records, financial documents, procurement workflows, and engineering files. Clop reportedly maintained access for months, exfiltrating 2.7 terabytes from Emerson and 116 gigabytes from Schneider Electric, with the breach going undetected by traditional monitoring tools.

Security experts warn that the impact extends beyond data theft, as attackers may leverage stolen information for extortion, supply chain exploitation, and credential harvesting. Oracle has released patches for CVE-2025-61882 and strongly urges all EBS customers to apply updates immediately. The campaign highlights the risks posed by trusted vendor dependencies and the potential for widespread disruption across critical infrastructure and operational technology supply chains. Attribution remains under investigation, with both Clop and the financially motivated FIN11 group suspected of involvement.
