South Korea’s Ministry of Science and ICT (MSIT) said Thursday it had lodged a strong protest after Coupang unilaterally disclosed what it called investigation results into a customer data breach, stressing that the claims have not been verified by the ongoing joint probe.

In a press release, the ministry said a public–private joint investigation team is still closely examining the type, scale and cause of the data leak. “The assertions made by Coupang have not been confirmed by the joint investigation team,” MSIT said.

Earlier in the day, Coupang posted a notice on its website stating that it had identified the leaker and secured all devices and hard disk drives used in the breach. The company claimed that, based on its investigation to date, the leaker stored customer information limited to about 3,000 accounts and subsequently deleted all of it.

Coupang also said it used forensic evidence, including “digital fingerprints,” to identify a former employee responsible for the leak, adding that the individual confessed to all actions and provided a detailed account of how customer information was accessed.

MSIT reiterated that any conclusions regarding the incident must come from the joint public–private investigation, cautioning against premature disclosures that could mislead the public while the probe remains underway.
