Recently, there has been a noticeable surge in cyber attackers exploiting remote access virtual private networks (VPNs) as a gateway for initiating network breaches. Various cybersecurity vendors have fallen victim to such compromises, prompting a reevaluation of their security measures, as highlighted in a recent blog post by Check Point.
Check Point’s chief of staff, Gil Messing, reported that as of May 24th, the company had encountered three attempted breaches using this method. Further investigation revealed a potential pattern, indicating a looming trend that could have serious implications. While the number of attempts globally may be minimal, the significance lies in recognizing the pattern and addressing the vulnerability to prevent future successful attacks.
Remote access VPNs play a crucial role in providing secure network access to specific individuals, unlike traditional VPNs that route Internet traffic through shared servers for anonymity. They are commonly utilized to facilitate remote workers’ access to internal company resources. Nonetheless, these same VPNs can be exploited by malicious actors to gain unrestricted access to an organization’s IT environment without the need for complex exploits or zero-day vulnerabilities.
One common tactic used by attackers, as uncovered by Check Point, is to target poorly secured accounts associated with outdated VPN credentials. By exploiting accounts protected solely by a single password, hackers can easily gain unauthorized entry to VPN connections.
To address these security risks, Check Point recommends organizations implement additional authentication measures beyond basic passwords to safeguard user accounts. Sectigo’s senior vice president of product, Jason Soroko, emphasizes the inadequacy of password-based authentication, advocating for modern alternatives such as certificate-based authentication. This method provides a more robust level of security by utilizing unique and unshared secrets for user verification, enhancing the authentication process while reducing the risk of password compromise.
Venky Raju, Field CTO at ColorTokens, stresses the urgency for organizations to transition from legacy VPNs to Zero Trust Network Access (ZTNA) solutions in light of recent security breaches. ZTNA offers inherent restrictions on user access based on the principle of least privilege, enhancing identity management integration and minimizing the likelihood of compromised passwords or misconfigurations. Raju also advises organizations to consult vendor documentation, remove unnecessary features, implement robust authentication protocols, audit default accounts, and establish a systematic patching process to fortify their security infrastructure.
In conclusion, the growing trend of attackers exploiting remote access VPNs highlights the critical need for organizations to enhance their cybersecurity measures against such threats. By adopting advanced authentication methods and transitioning to more secure access solutions like ZTNA, businesses can mitigate the risks posed by malicious actors seeking unauthorized access to their networks. Vigilance, proactive mitigation strategies, and continuous security updates are essential in safeguarding against evolving cyber threats in today’s digital landscape.
