Civic Group Demands Transparency as Korea‑U.S. Tensions Surface Over Coupang Data Leak
Updated (52 articles)
Data Leak Exposes Over 33 Million Coupang Users The personal information of roughly 33.7 million customers—including names, phone numbers and delivery addresses—was accessed in a breach that occurred last year, according to Coupang’s own disclosure [1]. The company’s internal investigation claimed a former employee stole the data but managed to delete records for only about 3,000 accounts [2]. Both articles note that the scale of the breach has prompted formal investigations by Korean authorities [2][1].
Regulator Demands Removal of Unverified Probe Results South Korea’s Personal Information Protection Commission ordered Coupang to take down its independent probe findings, labeling them “unverified” and warning they could mislead the public [2]. The commission warned that failure to submit required documents could be treated as obstruction and urged the firm to add a user‑facing breach‑lookup feature to its app and website [2]. This demand underscores the regulator’s push for an official, transparent investigation [2].
Civic Group Calls for Transparency and Compensation The Korean American Public Action Committee, representing Korean‑American interests, urged Coupang to fully disclose the breach’s scope and provide substantive compensation to affected users [1]. The group warned against using political lobbying or congressional hearings to conceal facts, emphasizing that mishandling could damage Seoul‑Washington relations [1]. Their statement reflects growing civil‑society pressure for corporate accountability in the wake of the leak [1].
Diplomatic Tensions Rise as US Lawmakers Criticize Korean Probe During a U.S. congressional hearing, a House member accused Korean regulators of targeting Coupang unfairly, suggesting the investigation could have discriminatory overtones [1]. South Korea’s Trade Minister Yeo Han‑koo traveled to Washington to discuss the issue with U.S. Trade Representative Jamieson Greer, asserting that the probe follows fair and transparent legal principles [1]. Both sides expressed a desire to prevent the dispute from escalating into a broader trade or diplomatic conflict [1].
