Hack, heist, and havoc: The Lazarus Group’s triple threat to global cybersecurity

Abstract

The Lazarus Group, a North Korean state-sponsored cyber threat actor, has become a significant player in cybersecurity. This case study examines the group’s cyber operations through a structured analysis of their techniques and tactics, which include social engineering, malware injection, disruption, evasion, and espionage. By progressing through these stages, the Lazarus Group combines human factor exploitation with technical prowess to execute high-impact campaigns, such as hacking, theft, and widespread disruption. This case classifies these campaigns into espionage, financial heists, and destructive operations, advancing North Korea’s strategic interests while exposing critical vulnerabilities in global cybersecurity. The analysis reveals how the interplay between human and organisational weaknesses, alongside systemic technical vulnerabilities, enables these large-scale cybercrimes. Key lessons are drawn from these operations, emphasising the necessity of addressing human and technical factors in cybersecurity frameworks. Furthermore, the case highlights the broader societal effects of cyberattacks, especially on critical infrastructure, and underscores the global impact of cybercrime. To counter such sophisticated threats, this study stresses the importance of international cooperation, cybersecurity awareness, and a comprehensive approach that addresses human and technical vulnerabilities.
