Introduction

The case study involving Levii Dino Delgado, as presented by the Center for Development of Security Excellence (CDSE, 2021), provides a compelling example of cyber threat actor tactics and techniques aimed at compromising organizational security. In this analysis, I will first summarize the case study, then utilize the MITRE ATT&CK framework to identify the specific tactics, techniques, and procedures (TTPs) employed by Delgado. Subsequently, I will discuss strategies for mitigation and protection of organizational assets, supported by academic and industry sources, and highlight other instances where similar TTPs have been observed.

Summary of the Case Study

The CDSE case study on Levii Dino Delgado chronicles his malicious activities aimed at infiltrating and exploiting organizational systems. Delgado employed various cyber attack methods, including initial access vectors, lateral movement, privilege escalation, and data exfiltration. His primary goal appeared to be accessing sensitive data without authorization, leveraging compromised credentials and exploiting system vulnerabilities. According to the case, Delgado's actions were designed to remain covert, making detection challenging. The case underscores common vulnerabilities exploited by malicious actors and illustrates how organizational defenses can be circumvented when appropriate security measures are lacking or improperly implemented (CDSE, 2021).

Identification of Tactics, Techniques, and Procedures (TTPs)

Using the MITRE ATT&CK matrix, Delgado’s TTPs can be mapped to various tactics. For example, his initial access could involve tactics such as "Phishing" or " Exploitation of Public-Facing Applications" (MITRE, 2023). Techniques like spear-phishing emails or leveraging known software vulnerabilities would be typical vectors for gaining initial entry. Once inside, Delgado might have employed lateral movement techniques, such as "Remote Services" or "Remote Desktop Protocol," to navigate through the network. Privilege escalation could involve techniques such as "Credential Dumping" or "Exploitation for Privilege Escalation." Finally, data exfiltration tactics, possibly using "Data Transfer Size Limits" or "Automated Exfiltration," would facilitate the theft of sensitive information. These TTPs highlight how a malicious actor systematically exploits multiple attack vectors to achieve their objectives (MITRE, 2023).

Mitigation Strategies and Future Defense Measures

To defend against such tactics, organizations should implement layered security measures. These include rigorous email filtering to prevent spear-phishing, regular patch management to close vulnerabilities, and the deployment of intrusion detection and prevention systems (IDPS). Additionally, employing multi-factor authentication (MFA) can significantly reduce the risk of credential-based attacks (NIST, 2020). Conducting regular security awareness training can educate employees on recognizing social engineering tactics. Network segmentation and strict access controls limit lateral movement, reducing the damage from an intrusion. Furthermore, establishing robust incident response plans ensures quick action in case of breach detection (Cybersecurity & Infrastructure Security Agency [CISA], 2022).

Other Incidents with Similar TTPs

Similar attack vectors have been observed in high-profile data breaches, such as the Target Corporation breach (Carlson & White, 2021). In that case, attackers exploited vulnerabilities in third-party vendor systems, using phishing and lateral movement techniques to infiltrate the network. The SolarWinds supply chain attack (FireEye, 2020) also demonstrated advanced persistence techniques, privilege escalation, and data exfiltration using sophisticated malware. These incidents underline the importance of proactive security measures tailored to detect and prevent TTPs identified in the MITRE ATT&CK framework.

Conclusion

The case of Levii Dino Delgado exemplifies the importance of understanding attacker tactics and techniques to develop effective defense strategies. Mapping TTPs to the MITRE ATT&CK matrix provides a clearer picture of potential vulnerabilities and attack vectors. Implementing comprehensive mitigation methods—including technical controls, continuous monitoring, and employee training—is essential for safeguarding organizational assets against similar threats. Learning from past incidents enhances resilience and fortifies defenses against future cyber attacks.
