The recent personal data breach at Coupang once again serves as a stark reminder of the weight of responsibility that companies and markets must bear in the digital economy. Now that online platforms have become foundational infrastructure in daily life, the protection of personal information is no longer optional; it is a core pillar sustaining trust in the marketplace. The fact that government ministries and offices are conducting a joint investigation, and that the National Assembly and law enforcement authorities are closely examining the matter, underscores just how firmly data protection has become a national priority. First and foremost, a responsible corporate response must come before all else. A large-scale data breach is not merely a technical misstep; it leaves a fracture in the relationship of trust between a company and its consumers. Coupang should not view this incident as a temporary crisis, but as an opportunity to overhaul its internal controls and security systems to meet global standards. A sincere apology, meaningful compensation and proactive, innovative measures
