S Korea hits Coupang with record fine over e-commerce data leak

South Korea hit e-commerce giant Coupang with a record $408 million fine Thursday over a leak that allegedly exposed more than 30 million customers' data.

Coupang, the country's largest online retail platform, signaled in a statement that it would challenge the fine in court.

The government's move caps a months-long probe into Coupang, which is incorporated in the United States.

Allegations of a massive data leak first surfaced in November.
