Seattle-based Coupang (CPNG) has steadily built one of the most formidable commerce engines in Asia, using South Korea as its proving ground. By pairing its own delivery network with streaming, food delivery, and everyday commerce, the company has spent billions crafting an ecosystem designed to deepen loyalty, compress delivery times, and keep competitors constantly playing catch-up.
That ascent was abruptly interrupted when a massive data breach rattled customers and regulators alike. Personal details linked to 33.7 million users, nearly Coupang’s entire user base, were exposed, sparking anxiety and frustration across the market. Although payment credentials were not compromised, the breach lingered for months, triggered police raids, and ultimately led to CEO Park Dae-jun stepping down in accountability.
