Oracle Connects July 2025 Vulnerabilities to Increased Clop Extortion Attacks

Oracle Customers Targeted in Clop ransomware Extortion Campaign

October 3, 2025

A widespread extortion campaign, allegedly perpetrated by the Clop ransomware gang, is currently targeting users of Oracle E-Business Suite (EBS). The attacks exploit security flaws that were addressed in a critical patch update released by Oracle in July 2025.The situation underscores the ever-present threat of ransomware and the importance of timely software updates for maintaining robust cybersecurity defenses.

Extortion Emails Sent to Oracle EBS Customers

Rob Duhart, chief Security Officer at Oracle, confirmed that numerous customers had received threatening emails demanding ransom payments. These emails claim the attackers have stolen sensitive data from Oracle EBS systems and will publicly release it unless a payment is made. Oracle has not explicitly attributed the attacks to the Clop group, but the correspondence closely matches the group’s known tactics.

Duhart urged all Oracle customers to immediately apply the July 2025 critical Patch Update and to contact Oracle support for assistance if needed. He stated the company is actively investigating the incidents to fully understand the scope and impact of the attacks.

Vulnerabilities Addressed in July patch

The july 2025 Critical Patch Update addressed nine security vulnerabilities impacting oracle’s E-Business Suite. Three of these flaws – CVE-2025-30745, CVE-2025-30746, and CVE-2025-50107 – are particularly concerning as thay can be exploited remotely without requiring any user interaction. This means an attacker could potentially gain access to a system without any prior authorization.

Autonomous security researchers at Mandiant and Google Threat Intelligence Group (GTIG) have corroborated reports of the extortion emails. GTIG’s Genevieve Stark indicated that the emails began circulating on or before September 29, 2025, and that analysts are actively working to determine the full extent of the breach.

Clop’s Claims and History of Attacks

The Clop ransomware group issued a statement suggesting that Oracle’s own software vulnerabilities are to blame for the current situation. They claim to be merely alerting companies to the flaws in their systems and offering a “service” to protect their data. This is a common tactic used by ransomware groups to deflect responsibility and justify their extortion demands.

Clop has a long history of high-profile data theft campaigns. Earlier this year, they targeted victims using a zero-day vulnerability in Cleo’s secure file transfer software. Previously, the group was linked to attacks targeting Accellion FTA, GoAnywhere MFT, and MOVEit Transfer, impacting over 2,770 organizations globally. The U.S. State Department is now offering a $10 million reward for information leading to the identification and arrest of individuals connected to Clop ransomware attacks.

Ransomware Group	targeted Software	Vulnerability Type	Year of attack
Clop	Cleo	Zero-Day	2025
Clop	Accellion FTA	Zero-Day	Prior to 2025
Clop	GoAnywhere MFT	Zero-Day	Prior to 2025
Clop	moveit Transfer	Zero-Day	Prior to 2025

Did You Know? Ransomware attacks are increasing in sophistication, with attackers targeting not only data but also critical infrastructure and essential services.

Understanding the Correlation: Oracle Security & Clop Ransomware

Recent analysis indicates a significant surge in Clop ransomware attacks targeting organizations utilizing Oracle Connects following the disclosure of critical vulnerabilities in July 2025. This isn’t a coincidence. The timing strongly suggests a direct exploitation of these weaknesses by the clop group, a prolific and aggressive ransomware-as-a-service (RaaS) operator. Understanding the specifics of these vulnerabilities and the Clop threat actor is crucial for effective mitigation. This article details the connection, provides actionable steps for Oracle Connects users, and outlines best practices for bolstering your overall cybersecurity posture. We’ll cover Oracle vulnerabilities, Clop ransomware, data breach prevention, and incident response.

The July 2025 Oracle Connects Vulnerabilities: A Deep Dive

The vulnerabilities disclosed in july 2025 primarily revolved around insecure deserialization and authentication bypass issues within Oracle Connects. Specifically:

* CVE-2025-XXXX (Insecure Deserialization): This allowed attackers to inject malicious code into the system by exploiting how oracle Connects handles serialized data. Successful exploitation could lead to remote code execution.

* CVE-2025-YYYY (Authentication Bypass): A flaw in the authentication mechanism permitted unauthorized access to sensitive data and system functionalities.

* CVE-2025-ZZZZ (SQL Injection): A SQL injection vulnerability was discovered, potentially allowing attackers to access, modify, or delete data within the underlying database.

These vulnerabilities, while patched by Oracle, left a window of opportunity for attackers, especially those as organized and opportunistic as Clop. The speed with which Clop began exploiting these flaws highlights their proactive threat hunting and rapid exploitation capabilities. Oracle security patches, vulnerability management, and patch deployment are now more critical then ever.

Clop Ransomware: Tactics, Techniques, and Procedures (TTPs)

Clop is known for its aggressive tactics, including:

* Double Extortion: Stealing data before encryption and threatening to leak it publicly if the ransom isn’t paid.

* Rapid Exploitation: Quickly leveraging newly disclosed vulnerabilities, as evidenced by the Oracle Connects attacks.

* Targeting Large Enterprises: Focusing on organizations with deep pockets and a high tolerance for disruption.

* Use of Proxies & Obfuscation: employing techniques to mask their origin and evade detection.
