| Intro · Why This Coupang Data Breach Is Critical

The recent Coupang data breach is more than a typical hacking incident. It is considered one of the largest breaches in Korea, exposing over 30 million accounts, including names, phone numbers, and delivery addresses.

What makes this incident even more serious is that attackers exploited a server authentication vulnerability, allowing them to access customer information without any login process.

The biggest concern is what comes next— the high likelihood of Coupang impersonation scams, smishing attacks, fake delivery messages, and phone fraud using the leaked information.

The government has launched an emergency cross-agency investigation team and announced a three-month enhanced monitoring period, including surveillance of the dark web.

This guide summarizes the government’s announcement and provides practical steps you can take immediately to protect yourself and minimize secondary damage.

| Immediate Protection Steps

Since the leaked information includes names, phone numbers, and home addresses, attackers may attempt sophisticated phishing or impersonation scams. These steps should be applied immediately.

Given the authentication vulnerability exploited in this incident, the risk of secondary scams is significantly higher than usual. Please apply these steps without delay.

| Government Response & Joint Investigation Team

The government has classified this incident as a major national security-level breach and immediately held an emergency meeting led by the Minister of Science and ICT.

A public–private joint investigation team has been launched to determine whether Coupang violated its legal obligations regarding access control, authorization management, and data encryption.

Authorities emphasized that this breach involves a platform deeply embedded in daily life, and thus requires a strengthened investigative approach.

| Major Secondary Risks

Because the leaked data includes full names, phone numbers, and home addresses, attackers can craft highly convincing scams based on real delivery information.

Among them, smishing and delivery-agent impersonation are considered the highest-risk vectors because attackers can use actual home addresses to gain victims’ trust.

| Additional Preventive Actions

Once the immediate safety steps are completed, the next stage is to establish a 3–6 month monitoring routine to minimize long-term risks.

Many fraud attempts occur months after a major data breach. Ongoing monitoring is the most reliable way to stay protected.

| Frequently Asked Questions

| Closing Remarks

This Coupang data breach has caused concern for many users because it occurred on a platform deeply tied to everyday life. The exposure of names, phone numbers, and home addresses significantly increases the risk of secondary fraud.

However, by applying the protection steps shared in this guide— smishing blocking, financial alerts, identity-theft protection, and family awareness— you can dramatically reduce the likelihood of harm.

The government has initiated a three-month monitoring period, including dark-web surveillance, and will continue investigating Coupang’s compliance with data protection rules.

If this information helped you, please consider sharing it with others. Wider awareness is the strongest defense against secondary damage.
