Cl0p Ransomware Group Exploits Oracle E-Business Suite Zero-Day, Exposes Thousands
November 2025 saw nearly 30 prominent organizations named by the Cl0p ransomware group after attackers exploited a critical Oracle E-Business Suite (EBS) vulnerability. The campaign demonstrates the high stakes of unremediated enterprise software flaws, as tens of thousands may face data exposure.
Vulnerability Details: CVE-2025-61882
The vulnerability, assigned CVE-2025-61882, impacts Oracle EBS versions 12.2.3 through 12.2.14 and allows unauthenticated attackers to execute remote code with system privileges. Exploitation facilitated complete system compromise and lateral movement into associated business data repositories. Key victims included The Washington Post, Logitech, Harvard University, and Cox Enterprises.
Technical Exploitation and Response
Attackers delivered custom payloads exploiting the vulnerable EBS SOAP interfaces, bypassing standard authentication checks and executing arbitrary code. The campaign’s breadth propelled rapid incident response within affected organizations, including emergency patch deployment, forensic imaging, and network segmentation. Security teams relied on SIEM (Security Information and Event Management) correlation rules focused on abnormal EBS process spawns and outbound data exfiltration signatures.
Wider Enterprise Impact
With more than 10,000 suspected affected entities, the attack sets a precedent for coordinated exploitation of critical business software. Oracle has since accelerated its patch release cycles and issued out-of-band advisories, but the event spotlights the ongoing challenge of reducing software supply chain risk and deploying security fixes at scale across global organizations.
Microsoft Azure Mitigates Record-Breaking 15.7 Tbps DDoS Attack from Massive IoT Botnet
Microsoft Azure successfully neutralized a distributed denial-of-service (DDoS) attack peaking at 15.72 terabits per second (Tbps), one of the largest ever recorded. The attack, targeting an Australian client, leveraged a botnet comprising over half a million compromised IoT devices, unleashing a wave of UDP floods and randomized port attacks.
Attack Composition and Botnet Analysis
The DDoS attack, attributed to the Aisuru botnet, achieved a throughput of 3.64 billion packets per second by exploiting poorly secured IoT devices worldwide. Attackers orchestrated high-velocity UDP-based floods, rotating source and destination ports to evade filtering, with volumetric payloads engineered to saturate data center edge links. Devices involved included home routers, networked cameras, and smart appliances lacking strong authentication or up-to-date firmware.
Defense Mechanisms and Service Continuity
Azure’s global scrubbing centers absorbed, analyzed, and mitigated malicious traffic using automated anomaly detection, real-time traffic classification, and granular rate limiting. No customer downtime was reported, affirming Azure’s investment in multi-layered DDoS protection and dynamic scaling of defense resources. The response demonstrates the effectiveness of hyperscale mitigation combined with traffic engineering algorithms based on source diversity, entropy detection, and protocol anomaly heuristics.
