In 2023, there was a significant increase in mass compromise events targeting network edge devices, with a shift towards more orchestrated attacks by single threat actors [2].
Description
Skilled adversaries continued to exploit vulnerabilities in network and security appliances as zero days, with memory corruption exploits being commonly used. Simpler issues such as command injection and improper authentication were also widely exploited. Rapid7 Labs reported tracking over 5,600 ransomware incidents in 2023 [4] [5], with a decrease in unique ransomware families [1] [4] [5]. Zero day attacks and widespread exploitation remained prevalent [2], with a trend of regressive practices among software vendors [2]. Notable vulnerabilities contributing to mass compromise events included CVE-2023-34362 and CVE-2023-0669 [3], as well as the Ivanti Connect Secure and Policy Secure authentication bypass flaw exploited by a Chinese nation state threat actor. Recommendations include implementing zero day patching procedures for critical technologies and mitigating vulnerabilities in network edge devices [1].
Conclusion
The increasing sophistication of cybercrime ecosystems and the continued targeting of simple root causes highlight the need for proactive security measures. Implementing zero day patching procedures [1], mitigating vulnerabilities in network edge devices [1], and enabling logging for security operations teams are crucial steps in addressing the ongoing threat landscape. The prevalence of zero day exploits and the vulnerability of network edge technology underscore the importance of strengthening collective defenses.
