In November 2025, Coupang Taiwan discovered a cybersecurity incident that exposed data from approximately 33.7 million customer accounts worldwide, including about 200,000 Taiwanese users. The compromised information reportedly included names, email addresses and hashed passwords, prompting an immediate internal security review.

To identify and remediate vulnerabilities, the company initiated a bug bounty program offering financial rewards to external researchers for reporting security flaws. The initiative aims to incentivize continuous testing of Coupang Taiwan’s systems and strengthen its defenses against future attacks.

At CYBERSEC 2026, Coupang Taiwan’s Chief Information Security Officer detailed the breach and outlined ongoing investigative measures, including forensic analysis and collaboration with third-party security firms. The CISO emphasized enhancements to encryption protocols and monitoring tools to prevent similar incidents.
