User Activity Rises Despite 34 Million Data Breach
DAU and MAU Reach All-Time Highs

Despite concerns over user attrition following the large-scale personal data breach affecting 34 million records at Coupang, both daily and monthly active user counts have reached all-time highs. This appears to be the result of a combination of established online shopping habits in everyday life and increased demand for account security checks.

According to mobile index data from the data tech company IGAWorks on December 4, Coupang’s daily active users (DAU) on December 1 reached 17,988,845, setting a new record for this metric. The DAU surpassed 17 million for two consecutive days, following 17,455,535 users on November 30.


Between November 29, when the data breach began to spread, and December 1, the number of users increased by more than 1.7 million. The DAU, which had remained in the 16 million range before the incident, broke records for consecutive days immediately after news of the breach was released.


The monthly figures also showed a clear upward trend. According to IGAWorks, Coupang’s monthly active users (MAU) for November stood at 34,420,207. WiseApp·Retail, which bases its data on app and payment information, also reported 34,398,407 users, with both figures marking all-time highs.


Industry experts attribute the limited user attrition despite the data breach to the high platform dependency built on delivery convenience. With services like dawn delivery and Rocket Delivery, as well as purchase patterns focused on discounts, these habits have become ingrained in daily life, making it difficult for users to switch to other e-commerce platforms in the short term.



An increase in logins for account security checks is also cited as a factor behind the rise in user numbers. As concerns over the data breach spread, more consumers accessed the Coupang app and website to review login history, check notifications and announcements, and change passwords. This surge in activity contributed to the increase in recorded user metrics.
