The large-scale personal data breaches involving SK Telecom and Coupang in 2025, along with the nationwide IT system outage at the National Information Resources Service, sent shockwaves throughout Korean society. Despite substantial budgets and advanced security solutions, basic security principles failed to function—such as leaving vulnerable servers unattended, failing to detect intrusions, and the malfunction of disaster recovery (DR) systems—leading these incidents to be viewed not as mere technical accidents but as structural failures.

These cases demonstrate that it was not the sophistication of the attacks, but rather organizational complacency, ignored warning signs, and overconfidence that ultimately undermined security. Partner Shinyoung Choi noted that Korea’s current security regulatory framework remains focused on formal compliance measures, and emphasized that future reforms should move beyond the mere possession of security solutions toward substantive supervision of organizational risk awareness, decision-making structures, and incident response systems.
