A massive data leak has affected online retail giant Coupang, with reports suggesting nearly 37.5 million users were impacted. The company has been fined a record amount, variously reported as $400 million or $409 million, over the breach. The incident has led to the CEO's resignation and a drop in sales, but its impact on broader retail policies is unclear, as separate reports indicate a longstanding ban on dawn deliveries for big-box retailers is set to be lifted.
