Coupang, a company that has been providing convenience to consumers as the largest e-commerce platform in Korea, has recently drawn public attention due to consecutive fines and a large-scale personal information leak. This crisis faced by Coupang goes beyond the issue of a single company, raising fundamental questions about the trust and transparency of the entire online distribution market. In particular, the fines imposed by the Fair Trade Commission for algorithm manipulation and employee review writing, along with the recent leak of personal information of tens of millions of people, are amplifying consumers' anxiety. This article will deeply analyze these two main issues and discuss the impact of these incidents on consumers and the importance of preparing practical measures to prevent recurrence in the future. Coupang's response and the government's regulatory moves will be an important turning point in determining the future e-commerce environment.
As of December 2, 2025, Coupang is experiencing a major ripple effect due to an unprecedented incident in which the personal information of over 33.7 million customers was leaked. This is expected to be recorded as the largest-ever personal information leak incident in Korea. Leaked information includes sensitive content such as customers' real names, phone numbers, and delivery addresses, increasing the possibility of being exploited in secondary crimes such as smishing and phishing, amplifying consumers' concerns. The Personal Information Protection Commission is aware of the seriousness of this situation and is reviewing the imposition of punitive fines of up to 1.33 trillion won on Coupang, and the Presidential Office is also ordering the strengthening of the effectiveness of the punitive damages system, signaling a strong response at the government level. Considering the previous cases where the company received lenient punishments despite three previous personal information leaks, it is noteworthy whether stronger sanctions will be imposed this time.
Even before the personal information leak incident, Coupang was at the center of controversy after being fined 162.8 billion won by the Fair Trade Commission for manipulating search ranking algorithms and writing reviews by mobilizing employees. According to the FTC investigation, from February 2019 to July 2023, Coupang was found to have fixed its own PB (Private Brand) products at the top of search results and induced consumers to purchase by having around 2,000 employees write positive reviews and high ratings. This is pointed out as an act that deprives consumers of the opportunity to make rational choices and undermines a fair competitive environment among sellers. Coupang has filed an administrative lawsuit against this and is engaged in a sharp legal battle with the FTC with the position that it "cannot accept the obligation of search neutrality."
This series of incidents involving Coupang causes direct damage and psychological anxiety to consumers. First, the large-scale personal information leak is a realistic threat that can lead to financial fraud such as voice phishing and smishing. Customers cannot help but be anxious about how far their sensitive information has been leaked and how it will be exploited. In addition, algorithm manipulation infringes on consumers' right to fairly compare various products and make the best choices. If the platform artificially exposes certain products at the top or induces purchases through manipulated reviews, consumers will find it difficult to make decisions based on rational information. This ultimately leads to a decline in trust in the platform, which can undermine the healthy growth of the entire e-commerce market in the long run.
The government and regulatory authorities are aware of the seriousness of this situation and are taking measures to prevent recurrence. The Personal Information Protection Commission will conduct a thorough investigation into Coupang's overall information protection management system in addition to the imposition of punitive fines, and the National Assembly has resumed discussions on the 'Online Platform Fairness Act (On-Platform Act)' to regulate unfair acts by online platforms and protect sellers. In addition, the Fair Trade Commission announced comprehensive measures to strengthen compliance with consumer protection obligations by all platform operators, including overseas online platforms, further emphasizing the responsibility of platforms. Companies also need voluntary efforts and transparent information disclosure to restore consumer trust beyond simply legal sanctions. The construction of a robust security system, ensuring the transparency of algorithms, and a quick and responsible response when problems arise are required.
The Coupang incident clearly shows the structural problems faced by the domestic e-commerce market. To create a healthy and sustainable online distribution environment in the future, the organic efforts of regulatory authorities, platform companies, and consumers are needed. Regulatory authorities should revise laws and systems in line with the rapidly changing digital environment and prevent platforms from abusing their authority through effective supervision and sanctions. Platform companies should go beyond short-term profit-seeking and establish a consumer-centered management philosophy while fulfilling their social responsibility. Transparent operation and the creation of a fair competitive environment will be the key drivers of long-term corporate growth. Consumers should also increase their awareness of personal information protection when using the platform and contribute to the formation of a healthy market through active monitoring and reporting of unfair acts.
The imposition of fines on Coupang and the large-scale personal information leak are sounding a serious alarm in the domestic e-commerce market. If safety and fairness are not guaranteed beyond convenience, consumers' avoidance is inevitable. With this incident as an opportunity, Coupang and all online platform companies should make consumer trust their top priority and seek a path to sustainable growth through transparent and responsible operation. The government and the National Assembly should establish effective legal and institutional measures to create a healthy digital ecosystem, and consumers hope that the online distribution market can further develop through a mutually cooperative relationship by actively exercising their rights.
