The 2025 Coupang data breach exposed personal information from more than 33 million accounts across Korea. While the incident affected users nationwide, many foreign residents found themselves unsure of what had happened or how serious the situation was, mainly because most official notices were released only in Korean.
For non-Korean speakers who rely on Coupang for everyday essentials, this lack of clear information created confusion about whether their data was involved, what risks they might face, and how to respond. This guide explains the situation in simple, practical terms and focuses on what foreign residents in Korea should check, prepare, and expect.
By the end of this article, you will understand what information was leaked, how to confirm your exposure, what steps to take to protect yourself, and whether foreigners are eligible for compensation or legal action.
Why This Matters for Expats in Korea
Foreign residents in Korea navigate a digital environment that is often built around Korean-language services, and Coupang is one of the few platforms that offers a partial English interface. Many expats depend on it not only for convenience but because it streamlines everyday life without requiring full Korean proficiency.
This dependence creates a unique vulnerability. When an incident like the 2025 Coupang data breach, known in Korean as 쿠팡 개인정보 유출, occurs, foreign residents face two challenges at once: the security risk itself and the difficulty of accessing timely, understandable information. Most official updates, security notices, and government statements are issued only in Korean, meaning many expats may not receive essential information until much later.
Additionally, expats often use multiple delivery addresses—temporary housing, shared apartments, office locations—which increases the chances that leaked data includes outdated or sensitive locations. Understanding the implications of the breach is therefore especially important for those living in Korea temporarily or without strong language support.
What Happened: The 2025 Coupang Data Breach at a Glance
In late 2025, Coupang confirmed a large-scale data breach affecting approximately 33.7 million customer accounts. This incident is considered one of the most serious data exposure cases in Korea’s e-commerce history.
The confirmed leaked information includes:
-
Name
-
Phone number
-
Email address
-
Delivery or shipping addresses
-
Parts of order history
Coupang stated that passwords and payment information were not leaked. However, the exposed data is still sensitive enough to increase the risk of phishing messages, identity misuse, and targeted scams.
According to early investigations, the breach may have been caused not by an external hacker but by a former internal employee with access privileges. Reports suggest that data might have been extracted quietly over several months, possibly beginning around June 2025. This long exposure period increases the likelihood of delayed or sophisticated scam attempts.
Was Your Data Leaked? How to Check in English
Many foreign residents struggled to confirm whether their accounts were affected, mainly because Coupang’s notices regarding the breach were written in Korean. Below is a simple, English-friendly method to check your own status.
How to check through the Coupang app or website:
-
Log in to your Coupang account.
-
Look for a banner or notification titled “개인정보 유출 안내” (Personal Information Leak Notice).
-
Select the banner and complete the verification steps.
-
The page will display which of your data fields were exposed.
If you do not see any banner:
-
Update the Coupang app and log in again.
-
Check the Notifications tab.
-
Visit Customer Service and review the Notices section for announcements.
-
Contact Coupang customer support through chat or phone. Limited English assistance is available, but they can guide you to the correct page.
Even if you have not received an alert, your account may still be part of the leaked dataset, so manual checking is strongly recommended.
Knowing your exposure status helps you understand what kinds of phishing attempts or fraud risks may appear in the coming weeks, especially since contact information and delivery addresses are commonly used in scam messages in Korea.
Immediate Actions to Protect Your Account
After a major incident like the 2025 Coupang data breach, or 쿠팡 개인정보 유출, simple early actions can significantly reduce future risks. Even if your payment information was not exposed, scammers often begin targeting users once they obtain phone numbers, emails, or addresses.
Recommended steps:
-
Change your password
Use a new, unique password that you do not use on other websites. Password reuse is one of the most common causes of account takeover. -
Enable two-step verification
Turn on phone or email verification for login attempts if available. This adds an extra layer of protection. -
Review old delivery addresses
Many expats move frequently. Remove outdated addresses, previous share houses, or office locations that are no longer relevant. -
Review connected services
Check if your Coupang account is linked to other apps or payment tools. Disconnect anything you do not use. -
Monitor your phone and email
If you begin receiving unusual messages, especially ones pretending to be delivery notices or account alerts, treat them cautiously.
Taking these steps now helps reduce the chance of being targeted later, especially as scammers often wait several weeks before acting.
Real Risks: What Scams Can Happen After a Leak
Even though Coupang stated that payment information and passwords were not leaked, the exposed data still carries meaningful risk. Information such as your name, phone number, email, and delivery address can be used to create highly convincing messages or calls.
Common risks after data leaks in Korea include:
-
Delivery-related phishing
Messages pretending to be from a courier service asking you to click a link or install an app. These scams often use real names and addresses to appear believable. -
Account suspension or verification scams
Fraudsters may send emails or texts saying your Coupang account is locked or under review, urging you to log in through a fake page. -
Targeted phishing
Criminals may tailor messages based on your recent purchases or order history, making them more difficult to identify as scams. -
Identity misuse
Although rare, leaked personal details can be used to attempt phone number transfers, create fraudulent accounts, or initiate unwanted financial activity. -
Combined data attacks
If your information from this incident is combined with older leaks, your risk increases. Attackers often use multiple data sources to build detailed profiles.
Understanding these risks helps you stay alert in the months following the breach. Scams often peak one to three months after the initial exposure.
Can You Get Compensation or Join a Lawsuit in Korea?
Many expats wonder whether foreigners are eligible to join any legal action related to the 2025 Coupang data breach. The short answer is yes. If your data was part of the leak, foreign residents have the same rights as Korean citizens in terms of filing complaints or joining collective lawsuits.
Key points:
-
Compensation is not yet finalized
As of now, Coupang has acknowledged the breach but has not announced a specific compensation plan. Government agencies are still reviewing the incident. -
Collective lawsuits are being prepared
Consumer groups and legal organizations in Korea are collecting information from users who wish to participate. These efforts include foreign residents as long as the affected Coupang account belongs to them. -
Language barriers
Most legal documents and announcements will be in Korean. Foreigners may need translation support or assistance from a Korean-speaking friend or legal adviser. -
What you should prepare
-
A screenshot or record showing your data exposure notice
-
Proof of your Coupang account
-
Any suspicious messages, calls, or attempted scams you received
-
A valid contact method for follow-up notices
-
-
Eligibility
You do not need to be a Korean citizen. You only need to confirm that your account was included in the 쿠팡 개인정보 유출 incident.
While compensation processes in Korea can take time, understanding your rights and preparing documentation early will make participation easier if a formal compensation program or lawsuit moves forward.
Long-Term Habits for Digital Safety in Korea
Even after the initial response to the 2025 Coupang data breach, known as 쿠팡 개인정보 유출, maintaining long-term digital safety is important. Data leaks often create risks that continue for months or even years, especially when criminals combine information from multiple sources.
Below are practical habits that can help protect foreign residents in Korea:
-
Use unique passwords
Avoid reusing passwords across websites. If one site is compromised, others become vulnerable. -
Enable verification on major accounts
Set up two-step or two-factor verification for email, banking apps, and online shopping accounts. -
Clean up old accounts
Many expats create temporary accounts during their stay. Delete accounts you no longer use. -
Check your bank and card statements
Review transactions regularly. Even small unfamiliar charges may indicate attempted fraud. -
Monitor your phone contract and identity use
In Korea, your mobile number is tied to identity verification. If anything appears unusual, contact your telecom provider quickly. -
Update personal information when you move
Many expats change apartments often. Remove old delivery addresses from shopping apps, including Coupang. -
Stay informed
Keep an eye on official announcements from government agencies or large platforms. Even if the information appears only in Korean, online translations can help.
Developing these long-term habits reduces the chance of becoming a target after the initial attention around the data breach fades.
