OEM | Microsoft |
Severity | High |
CVSS | 7.8 |
CVEs | CVE-2018-8639 |
Exploited in Wild | Yes |
Patch/Remediation Available | Yes |
Advisory Version | 1.0 |
Overview on Vulnerability
The vulnerability gives hackers the ability to install persistent malware, get around security measures, and alter system operations covertly. The Cybersecurity and Infrastructure Security Agency (CISA) has included this vulnerability in its Known Exploited Vulnerabilities (KEV) catalog, further highlighting its ongoing threat.
Vulnerability Name | CVE ID | Product Affected | Severity |
Privilege Escalation Vulnerability | CVE-2018-8639 | Windows | High |
Technical Summary
The vulnerability exists within the Win32k.sys driver, which handles graphical user interface (GUI) interactions.
Designated as CWE-404: Improper Resource Shutdown or Release, the flaw enables authenticated local attackers to improperly release system resources, leading to privilege escalation. Exploiting this vulnerability grants kernel-mode execution rights, allowing attackers to bypass security mechanisms, install persistent malware, and manipulate system functions without detection.
CVE ID | System Affected | Vulnerability Details | Impact |
CVE-2018-8639 | Windows 7, 8.1, 10, RT 8.1, Windows Server 2008, 2008 R2, 2012, 2012 R2, 2016, 2019 | Improper Resource Shutdown or Release in Win32k.sys driver, enabling privilege escalation. | System compromise, unauthorized access, potential malware persistence |
Remediation:
General Recommendations:
Conclusion:
Unpatched Windows systems are particularly vulnerable, especially in industrial control systems (ICS) and healthcare facilities where obsolete software is ubiquitous. While Microsoft has fixed the issue, firms that rely on legacy systems must implement additional security measures. Cyber adversaries are always refining their exploitation techniques, making proactive security strategies critical to reducing risk.

OEM | CISCO |
Severity | High |
CVSS score | 7.4 |
CVEs | CVE-2025-20111 |
Exploited in Wild | No |
Patch/Remediation Available | Yes |
Advisory Version | 1.0 |
Overview
A high-severity vulnerability (CVE-2025-20111) in Cisco Nexus 3000 and 9000 Series Switches operating in standalone NX-OS mode could allow unauthenticated attackers to trigger a denial-of-service (DoS) condition by sending crafted ethernet frames, leading to unexpected device reloads.
Vulnerability Name | CVE ID | Product Affected | Severity |
Denial of service vulnerability | CVE-2025-20111 | Cisco Nexus | High |
Technical Summary
The vulnerability originates from improper handling of specific Ethernet frames within the health monitoring diagnostics of Cisco Nexus switches.
An unauthenticated, adjacent attacker can exploit this flaw by sending a sustained rate of crafted Ethernet frames to a vulnerable device. Successful exploitation results in repeated device reloads, disrupting network operations and potentially impacting high-availability environments.
CVE ID | System Affected | Vulnerability Details | Impact |
CVE-2025-20111 | Nexus 3000 Series: 3100, 3200, 3400, and 3600 models Nexus 9000 Series: 9200, 9300, and 9400 switches running standalone NX-OS | Improper handling of specific Ethernet frames in health monitoring diagnostics | Repeated device reboots, potential network downtime |
Remediation:
Conclusion:
CVE-2025-20111 presents a significant risk to enterprise and data center networks relying on Cisco Nexus switches. While there is no known active exploitation, organizations should prioritize patching and mitigation strategies to prevent service disruptions. Proactive monitoring and adherence to Cisco’s security advisories will help ensure network resilience against potential exploitation.

Threat actors aimed infiltrating on Orange’s systems; A case of Ransomware cannot be denied on the data breach that took place.
Orange has confirmed it has recently experienced a cyber-attack, that exposed compromised data. Orange insists it is still investigating the case. The data breach on Orange group when analyzed found it included thousands of internal documents, including sensitive user records and employee data, after infiltrating the company’s infrastructure.
As per reports one of Orange’s non-critical apps breached in an attack aimed at its Romanian operations after HellCat ransomware gang member “Rey” alleged exfiltrating thousands of internal files with user records and employee details, which have been leaked on Tuesday, according to BleepingComputer.
Key Breach details on Orange Group
Cyber Security Implications
From cybersecurity point the incident reflected how major organization face cyber threats and what is their strategy for incident response?
How far is the preparedness of enterprises against a ransomware attack?
These are some of the eminent questions organizations must face in order to defend their brand name..Is it proactive, are organizations prepared as Ransomware groups are focusing with advanced techniques.
Cyber security preparedness the next step
It is important that security teams be on their toes to stop any ransomware attack at the source.
AI on the endpoints is the requirement of the day, detecting atypical behavior to predict and block attack advances, at the same time before encryption, having visibility full visibility from the kernel to the cloud enables one to spot signs of compromise .This can also be any ransomware chain or any early indicators of compromise.
Experts keep on warning how to protect assets from getting compromised warning customers and employees to remain vigilant for potential phishing attempts based on the data that has been leaked.
AI Leveraging Ransomware campaigns
Earlier we witnessed cybercriminals would encrypt data and provide the decryption key once payment was received.
Now threats has doubled up with double or triple extortion attacks to expose stolen information on data leak sites in exchange for larger ransoms.
The greater availability of artificial intelligence and machine learning tools has led to these gangs be more sophisticated in their attack methods. Now the attack vectors leverage AI and ML capabilities to evade detection, spread more effectively to reach their final goals.
AI Reshaping Cyber security Roadmap
AI in cybersecurity firstly integrates artificial intelligence technologies that are required to gain critical insights and automate time-consuming processes and this includes machine learning and neural networks, into security frameworks.
These technologies are a must to enable cybersecurity teams and systems to analyze vast amounts of data, recognize attack patterns, and being able to adapt new evolving threats that can be performed with minimal human intervention. Read our blog: AI Reshaping Roadmap for Cyber security
With AI capabilities what is the next scenario we may witness in Ransomware campaigns
AI-driven systems learn from experiences and AI will empowers organizations, enterprises in future and still doing to enhance their cybersecurity posture and reduce the likelihood of breaches, identify potential risks by acting independently.
