CVE exploits in 2024 have seen a significant rise, with 768 vulnerabilities actively exploited, marking a 20% increase from 2023. This surge highlights a growing trend in cybercriminal activities, where threat actors rapidly weaponize newly discovered vulnerabilities, exposing businesses to critical security threats.
A report from VulnCheck revealed that 23.6% of exploited vulnerabilities were targeted on or before their public disclosure. While this number is slightly lower than 2023’s 26.8%, it emphasizes that attackers do not wait for organizations to patch before launching cyberattacks. Additionally, experts predict the number of exploited CVEs will continue to rise, as many vulnerabilities go undetected for extended periods.
Given the increasing volume of CVE exploits in 2024, organizations must take proactive steps to patch vulnerabilities, monitor for active threats, and implement strict security protocols.
Why CVE Exploits in 2024 Increased
The Acceleration of Exploit Weaponization
Cybercriminals are acting faster than ever, targeting vulnerabilities within hours of disclosure. Several factors contributed to this 20% increase in CVE exploits:
- Rapid exploit development – Attackers quickly create automated tools to exploit new vulnerabilities.
- Expanding attack surfaces – The widespread adoption of cloud platforms, IoT devices, and hybrid work environments has increased security risks.
- Advanced cybercriminal tactics – State-sponsored threat actors and ransomware gangs strategically target critical vulnerabilities.
These trends emphasize why organizations must prioritize vulnerability management and rapid incident response.
Most Exploited CVEs in 2024
Among the 768 actively targeted vulnerabilities, several affected widely used enterprise software and security solutions. The most exploited vulnerabilities impacted:
- Microsoft – Windows Server, Exchange, and Office 365 security flaws.
- Cisco & Fortinet – Exploited VPN and firewall vulnerabilities.
- Citrix & Atlassian – Remote access exploits enabling unauthorized access.
- Zoho & Progress Software – Business-critical applications targeted by attackers.
- Apache & PaperCut – Open-source software vulnerabilities exploited in ransomware campaigns.
Many of these CVEs have been linked to ransomware deployments, espionage, and financial fraud schemes, further increasing the urgency to apply patches.
The Persistent Threat of Log4j & Legacy Vulnerabilities
Log4j Remains a Major Exploited CVE in 2024
Despite being disclosed in 2021, the Log4j vulnerability (CVE-2021-44228) continues to be one of the most exploited security flaws. VulnCheck’s report states that 31 named threat actors actively use this exploit, with 65,245 hosts still vulnerable.
The persistence of Log4j attacks highlights ongoing security lapses and the failure to enforce strict patching policies. Without continuous monitoring, organizations will remain vulnerable to exploitation of legacy vulnerabilities.
Cybercrime Groups & Nation-State Threat Actors
State-sponsored hacking groups, particularly those linked to China, were responsible for exploiting at least 15 of the most critical CVEs in 2024. These nation-state attackers focused on:
- Government agencies
- Technology firms
- Financial institutions
- Defense contractors
Additionally, ransomware gangs and cybercriminal syndicates capitalized on these vulnerabilities to:
- Deploy ransomware payloads on unpatched systems.
- Use stolen credentials for lateral movement inside networks.
- Sell access to compromised environments on dark web forums.
With over 400,000 internet-facing systems still vulnerable, organizations must prioritize patching and security hardening to prevent breaches.
How to Protect Against CVE Exploits in 2024
1. Strengthen Patch Management & Vulnerability Response
- Apply security patches immediately for high-risk CVEs.
- Automate patch deployment to minimize delays.
- Conduct regular vulnerability scans to identify unpatched systems.
2. Leverage Threat Intelligence for Risk Monitoring
- Track Known Exploited Vulnerabilities (KEVs) in real time.
- Use AI-powered security analytics to detect patterns of attack.
- Implement Security Information and Event Management (SIEM) solutions for continuous monitoring.
3. Reduce Attack Surface & Implement Zero Trust Security
- Minimize internet-facing exposure for vulnerable applications.
- Segment networks to prevent unauthorized lateral movement.
- Enforce strict access controls and multi-factor authentication (MFA).
4. Deploy Multi-Layered Cybersecurity Defense
- Use Endpoint Detection and Response (EDR) solutions.
- Leverage next-generation firewalls (NGFWs) with AI-driven security.
- Train employees on phishing, credential theft, and exploit prevention.
5. Conduct Continuous Security Assessments
- Subscribe to threat intelligence feeds for early warnings.
- Perform penetration testing to uncover weaknesses.
- Partner with cybersecurity experts to establish a robust security strategy.
Final Thoughts: CVE Exploits in 2024 Demand Immediate Action
The rising number of CVE exploits in 2024 reinforces the need for proactive cybersecurity measures. Attackers no longer wait for vulnerabilities to be patched—they actively seek zero-day vulnerabilities and unpatched systems to infiltrate networks.
By focusing on timely patching, real-time threat monitoring, and advanced security defenses, organizations can mitigate risks and strengthen their cybersecurity posture. Moving into 2025, businesses must adopt continuous risk assessment, adaptive security strategies, and intelligence-driven defense mechanisms to stay ahead of evolving threats.
