The police have raided the offices of South Korea’s biggest ecommerce store, Coupang, as it investigates one of the largest data breaches in the country’s recent history.

In the final days of November, Coupang confirmed suffering a cyberattack and losing personally identifiable information (PII) of 34 million customers. As per the company’s CEO, the attack started in June 2025, and it wasn’t spotted for almost half a year.

During that time, the attacker exfiltrated people’s names, emails, phone numbers, shipping addresses, and specific order information, putting them at serious risk of identity theft and fraud.
