In December 2023 and January 2024, a flurry of vulnerabilities in Ivanti’s Connect Secure and Policy Secure VPN products sent shockwaves through the cybersecurity world. Exploited by multiple threat actors, these zero-day vulnerabilities, dubbed CVE-2023-46805, CVE-2024-21887, and CVE-2024-21888, exposed a major supply chain security risk and the potential for widespread compromise.

Let’s delve into the incident, its implications, and crucial steps to mitigate similar risks in the future.

The Breach Breakdown:

  • Zero-Day Threats: The vulnerabilities allowed attackers to bypass authentication, gain initial access, and escalate privileges within target networks. Exploit code was readily available online, leading to widespread exploitation.
  • Global Impact: Thousands of organizations across various industries, including government agencies, were potentially affected. Cybercriminals used the vulnerabilities for data exfiltration, lateral movement, and ransomware deployment.
  • CISA Intervention: The US Cybersecurity and Infrastructure Security Agency (CISA) issued emergency directives mandating federal agencies to patch the vulnerabilities immediately due to the severity of the threat.

Lessons Learned and Implications:

The Ivanti incident highlights several critical aspects:

  • Supply Chain Risks: Third-party software vulnerabilities can have downstream consequences affecting all users. Careful vendor selection and risk assessments are paramount.
  • Zero-Day Dangers: Zero-day exploits pose a significant challenge, requiring rapid patching and proactive defense measures.
  • The Importance of Patching: Regular and timely patching of vulnerabilities is crucial to minimize attack surfaces and reduce risks.
  • Multi-Factor Authentication (MFA): Implementing MFA can significantly mitigate the impact of compromised credentials.
  • Network Segmentation: Segmenting networks can limit the impact of attackers who gain initial access through vulnerabilities.

10 Steps to Stay Secure:

  1. Prioritize patching: Patch all software, especially critical infrastructure, promptly.
  2. Implement MFA: Enforce MFA on all critical accounts and privileged access.
  3. Conduct regular vulnerability scans: Identify and address vulnerabilities before attackers exploit them.
  4. Segment your network: Minimize the impact of breaches by segmenting critical systems and data.
  5. Monitor user activity: Detect suspicious activity and potential compromises early.
  6. Educate employees: Train employees on cybersecurity best practices and phishing awareness.
  7. Have an incident response plan: Be prepared to respond to security incidents efficiently.
  8. Stay informed: Follow cybersecurity news and updates to stay aware of emerging threats.
  9. Consider third-party security assessments: Enhance your security posture through audits and vulnerability assessments.
  10. Invest in threat intelligence: Gain insights into active threats and relevant attacker tactics.


The Ivanti incident serves as a stark reminder of the evolving cybersecurity landscape and the importance of proactive defense. By prioritizing patching, implementing security best practices, and staying informed, organizations can significantly reduce their risk of falling victim to similar attacks. Remember, cybersecurity is an ongoing process, and vigilance is key in protecting your organization and data in today’s interconnected world.
