Coupang breach prompts scrutiny from South Korean regulators

South Korea is examining a significant data breach at Coupang after the retailer confirmed exposure of personal details linked to millions of users. Officials say the incident involves only domestic accounts. Regulators have opened a formal investigation.

Coupang first reported a small number of affected users, then revised its estimate to 33.7 million. The firm states that the leaked data includes names and contact details. It maintains that passwords and payment information remain secure.

Authorities believe the breach may date back several months and may involve an overseas server. Local media reports suspicion of a former employee in China. Investigators are assessing whether safety rules were breached.

The incident adds to a series of cyberattacks on major firms in South Korea this year. Commentators say repeated lapses point to structural weaknesses. Previous breaches at SK Telecom and Lotte Card remain fresh in public memory.

Coupang has apologised and warned customers to watch for scams using stolen information. Regulators pledge to enforce swiftly if violations are confirmed. The case has reignited debate over corporate safeguards and national cyber resilience.
