South Korea fines Coupang ₩624 billion over data breach affecting 34 million customers

Colleagues, a cybersecurity alert: South Korea’s Personal Information Protection Commission fined Coupang ₩624 billion (over $400M) after a breach affecting more than 34 million customers.

What happened:
- Breach detected in December 2025; a former employee obtained names, emails, addresses, phone numbers and order histories.
- The Commission imposed the maximum penalty; Coupang plans to appeal.
- A rare precedent for U.S.-listed companies; it has sparked political friction among lawmakers.

Why it matters: it underscores a global shift toward strict liability for data protection.

Will the fine change how international firms store and process data?
