Data breach hits ‘South Korea’s Amazon,’ potentially affecting 65% of country’s population

Posted on December 1, 2025December 1, 2025 by Dissent

Alexander Martin reports:

South Korea’s largest online retailer, Coupang — often described as the country’s version of Amazon — apologized on Sunday after confirming that the personal details of 33.7 million customer accounts had been compromised.

It is the latest high-profile data breach to have affected South Korean companies, with 27 million customers of SK Telecom and 3 million customers of Lotte Card informed of incidents earlier this year.

In response to the Coupang breach, the South Korean government held an emergency meeting on Sunday of senior officials including the deputy prime minister, Yun-cheol, the minister of science and ICT, Bae Kyung-hoon, and the acting commissioner general of the Korean National Police Agency, Yoo Jae-seong.

[…]

South Korean news reports have suggested that no malicious code has been found on Coupang’s internal systems. Reported suspicions for the breach are centering on a former employee.

The Yonhap news agency reported that police believe they have identified the perpetrator. It described them as a Chinese former employee who has since left the country, although this has not been confirmed by police.
