Calling the assessment “unilateral,” Korean authorities are continuing their probe, including analysis of a laptop linked to the breach.
Coupang said on Nov. 29 that data from about 33.7 million customers had been exposed, though it later said only around 3,000 accounts were retained and deleted by the perpetrator.
E-commerce giant Coupang saw its weekly users fall about 6 percent during the month since it revealed a data breach that occurred last year, data showed Monday, as security concerns spread across the online retail market, including Chinese platforms.
