Increased apprehension has gripped South Korea following a significant data leak at e-commerce giant, Coupang. Officials have indicated that this breach could have been overlooked for an extended period.

Scale of Data Leakage

Coupang, a United States-listed merchant, revealed on a recent Saturday that the private information of 33.7 million consumers, essentially its entire client base, had been jeopardized. The vulnerable data encompass names, contact numbers, email addresses, and delivery locations. The company reassured that financial information, credit card specifics, and login details remained untouched.

Based on Coupang’s findings, unauthorized infiltration into the delivery-related private data seems to have been carried out via foreign servers from June 24 onwards.

Investigation Update

Individuals familiar with the situation have shared that the police have pinpointed at least one suspect. The person is allegedly a former Chinese worker of Coupang who has since dissociated from both the company and the nation. The authorities initiated an inquiry after receiving a complaint.

Coupang confirmed detecting the data leak on November 18 and informed the regulators within the subsequent two days. The corporation initially stated that approximately 4,500 accounts had been impacted.

Implications of the Breach

The magnitude of the data exposure, which is now proven to be considerably more extensive and long-standing than initially conveyed, has unsettled consumers. They are apprehensive that their data might be exploited for fraudulent activities or phishing strategies. The event now surpasses the cyber breach at SK Telecom in April, which affected data from 23.2 million users and led to a record penalty of 134.8 billion won.

The final repercussions could escalate as the investigation progresses. A similar recent incident involving Lotte Card initially denied leakage of financial data following a breach in September. The company had to backtrack two weeks later and admit that credit card numbers and other critical data had indeed been laid bare.
