The Rising Threat of Brute-Force Attacks on VPNs and SSH Services

Share This

In an increasingly interconnected world, the importance of robust cybersecurity measures cannot be overstated. A recent report by Talos Intelligence highlights a concerning trend in cyber threats: large-scale brute-force attacks targeting Virtual Private Networks (VPNs) and Secure Shell (SSH) services. These attacks, which utilize commonly used login credentials, underscore the critical need for organizations to enhance their security protocols to safeguard their digital assets.

Understanding Brute-Force Attacks

Brute-force attacks are relatively simple yet effective techniques used by cybercriminals. These attacks involve automated systems that rapidly guess login credentials to gain unauthorized access to user accounts. The simplicity of the method belies its potential for destruction, particularly when it targets essential services like VPNs and SSH. These services are often used by businesses to enable secure remote access to their networks, making them prime targets for attackers looking to breach secure environments.

The Role of Common Credentials

The effectiveness of brute-force attacks is significantly amplified by the use of common usernames and passwords. Many users and organizations continue to employ easily guessable passwords, and the reuse of passwords across multiple services remains a prevalent issue. This practice provides a fertile ground for cybercriminals to exploit and gain access to sensitive information and critical systems.

Implications for Businesses

The implications of such attacks are far-reaching. Unauthorized access can lead to data breaches, loss of sensitive or proprietary information, and significant financial and reputational damage. Moreover, the breach of a VPN or SSH service can compromise the security of all connected systems and networks, magnifying the potential impact.

Fusion Computing’s Managed Cybersecurity Approach

At Fusion Computing, we understand the criticality of securing VPN and SSH access points against such threats. Our managed cybersecurity services are designed to provide comprehensive protection through several key strategies:

  • Strong Authentication Practices: We advocate for and help implement multi-factor authentication (MFA) and the use of strong, unique passwords for each service.
  • Regular Security Audits and Vulnerability Assessments: Our team conducts regular checks to identify and mitigate vulnerabilities that could be exploited by brute-force attacks.
  • Security Awareness Training: We provide ongoing training to employees, emphasizing the importance of cybersecurity best practices and the dangers of using common credentials.
  • Advanced Threat Detection and Response: Our security operations team utilizes cutting-edge tools to detect unusual login attempts and respond promptly to potential breaches.


The rise in brute-force attacks targeting VPNs and SSH services is a stark reminder of the ever-evolving cyber threat landscape. Organizations must prioritize the implementation of robust security measures to protect against these types of attacks. Fusion Computing is dedicated to partnering with businesses to strengthen their cybersecurity defenses, ensuring they are well-equipped to handle current and future cyber threats.
