Hearing Structure and Witness List: The National Assembly will convene a two‑day hearing starting Tuesday, involving six parliamentary committees—including the Science and ICT Committee—to scrutinize the breach [1][2]. Thirteen current and former Coupang executives are slated to appear as witnesses, though several have already submitted statements indicating they will not attend [1][2]. The hearing aims to assess both the technical causes of the leak and alleged unfair business practices [1].

Opposition Party Stance and Boycott: The People Power Party, the main opposition, has chosen to boycott the proceedings, arguing that a parliamentary inspection would be more appropriate [1]. Party leaders have publicly criticized the hearing format and expressed concerns about politicization of the investigation [1]. Their boycott underscores broader partisan tensions surrounding corporate accountability in South Korea [1].

Scale of Data Breach and Personal Information Exposed: The leak compromised personal data from roughly 33.7 million customer accounts, nearly 34 million individuals [1][2]. Exposed information includes names, phone numbers, email addresses, and delivery addresses, representing one of the largest data breaches in the country’s e‑commerce sector [1][2]. Police investigations are ongoing to determine the breach’s origin and responsible parties [1].

Executive Non‑Attendance and Lawmaker Reaction: Founder Kim Bom‑suk, his brother Yoo Kim, and former CEO Kang Han‑seung have each filed statements refusing to attend, citing overseas residence and pre‑arranged schedules [1][2]. Rep. Choi Min‑hee, chair of the Science, ICT, Broadcasting and Communications Committee, posted on social media that such absences should be disapproved [2]. Their non‑appearance has drawn criticism from lawmakers seeking direct accountability [2].

Coupang’s Internal Findings and Government Response: Coupang reports it identified a former employee as the hacker, using forensic evidence, recovered the compromised equipment, and secured a confession [2]. The government labeled these results a unilateral claim and noted that a joint public‑private investigation launched last month has yet to release its findings [2]. This tension highlights the need for coordinated investigative efforts to resolve the breach fully [2].
