'Coupang Falls Over 5% on US Stock Market After Data Breach Affecting 33.7 Million'

First Trading Day After Massive Data Breach Disclosure
Bloomberg: "Reveals South Korea's Cybersecurity Vulnerabilities"

On December 1 (local time), Coupang's stock price plunged more than 5% on the New York Stock Exchange following a massive personal information leak incident.

On this day, Coupang, listed on the New York Stock Exchange (NYSE), closed at $26.65 per share, down 5.36% from the previous trading day. This marked the first trading session on the NYSE since the incident was made public.

Previously, Coupang, the top e-commerce company in South Korea, announced on November 30 that the personal information of 33.7 million customers had been leaked. Names, phone numbers, home addresses, and emails were all exposed externally, and it was revealed that this data breach had continued for five months without the company noticing. As a result, Coupang's inadequate personal information protection system has come under heavy criticism.

Bloomberg News pointed out, "The massive data leak at Coupang, South Korea's largest e-commerce company, is the biggest online information breach in the country this year," adding, "It clearly exposes the vulnerabilities of South Korea's cybersecurity."
