Top Highlights
- Cybercriminal group Cl0p, linked to FIN11, targeted nearly 30 organizations via a campaign exploiting Oracle EBS vulnerabilities, with some victims publicly confirmed, including Harvard and American Airlines’ Envoy Air.
- The attack involved extortion emails in late September, with Cl0p leaking data from 18 victims, potentially originating from Oracle environments, and may have exploited zero-day flaws (CVE-2025-61882/84).
- Most impacted organizations are yet to confirm breaches; many remain silent, likely due to ongoing investigations or strategic withholding of information.
- The campaign’s proximity to previous Cl0p attacks signifies a pattern of high-impact, targeted data breaches leveraging Oracle EBS vulnerabilities over recent months.
What’s the Problem?
Recently, a series of cyberattacks targeting organizations using Oracle’s E-Business Suite (EBS) was uncovered, involving a threatening campaign where extortion emails were sent to senior executives across nearly 30 entities. This campaign was attributed to a financially motivated group known as FIN11, which appears to have employed the Cl0p ransomware group as its public face, leveraging its reputation from previous high-profile attacks on firms like Cleo, MOVEit, and Fortra. The attack led to the leaking of data from at least 18 organizations, including prominent institutions such as Harvard University, Wits University in South Africa, and a subsidiary of American Airlines. While some victims confirmed breaches, many remain silent, either investigating or choosing not to disclose details, with a few data leaks reportedly exposing hundreds of gigabytes or even terabytes of potentially sensitive files.
The attackers seemingly exploited known vulnerabilities, likely CVE-2025-61882 and CVE-2025-61884, which allowed remote and unauthenticated access to sensitive data within Oracle EBS systems. The timing suggests at least one zero-day exploit was used months before patches were issued. The victims span a broad range of sectors—including manufacturing, finance, energy, and technology—and, according to cybersecurity analysts, the data probably originated from Oracle environments. While some organizations remain tight-lipped during investigations, the pattern of targeted attacks, combined with the leaked data’s scope and the hackers’ history, indicate a calculated effort to compromise and threaten large corporations using Oracle’s enterprise solutions.
What’s at Stake?
The alarming revelation that nearly 30 alleged victims of an Oracle E-Business Suite (EBS) breach are now exposed on the Cl0p ransomware site underscores a widespread vulnerability that could seriously threaten any business, regardless of size or industry; such a breach can lead to severe consequences, including data theft of sensitive customer and proprietary information, debilitating operational disruptions, hefty financial penalties, and irreparable damage to reputation, all of which cumulatively diminish trust and competitive standing in the marketplace—highlighting the urgent need for robust cybersecurity measures and proactive threat mitigation to prevent your organization from becoming the next victim.
Possible Action Plan
In the rapidly evolving landscape of cyber threats, quick and effective remediation following a breach is critical to minimizing damage, preventing further exploitation, and restoring trust in the affected systems.
Immediate Response

- Conduct a comprehensive malware scan and remove malicious code.
- Disable compromised accounts and reset passwords.
Assessment & Analysis
- Gather and analyze logs to understand the breach scope and entry points.
- Identify and document affected data and systems for prioritization.
Communication & Notification
- Inform internal stakeholders and affected parties in compliance with legal requirements.
- Coordinate with cybersecurity authorities and advisory bodies.
Mitigation & Recovery
- Patch vulnerabilities and update software to fix known exploits.
- Deploy updated security configurations and enforce access controls.
- Rebuild or restore affected systems from clean backups.
Monitoring & Prevention
- Implement continuous monitoring for unusual activity.
