Coupang: Coupang shares rally as scope of data breach was limited, hacked data retrieved

**Coupang Shares Rally After Limited-Scope Data Breach Contained**

South Korean e-commerce giant Coupang saw its stock surge at Friday’s market open after confirming that a recent data breach was contained, with no evidence of stolen user data being shared with third parties. The company stated that the perpetrator had been identified and that all compromised data had been retrieved.

Details on the timing, attack vector, or specific data types affected were not disclosed. The incident follows growing concerns over cybersecurity risks in the e-commerce sector, where customer data—including payment details and personal information—remains a prime target for threat actors.

While Coupang’s swift response appears to have mitigated broader fallout, the breach underscores the persistent vulnerabilities in digital retail platforms. The company’s assurance of limited exposure helped restore investor confidence, though the long-term impact on user trust remains to be seen.
