Coupang Data Breach: Securities Class Action Lawsuit and Executive Departure (2026)

A Data Breach Scandal Unveiled: The Fall of Coupang's Reputation and Investor Trust

In a shocking turn of events, Coupang, Inc. (CPNG) finds itself at the center of a securities class action lawsuit, amidst a massive data breach and a series of questionable decisions. The lawsuit, Barry v. Coupang, Inc., et al., has been filed on behalf of investors who acquired Coupang securities during a specific period, and it raises serious concerns about the company's transparency and timely disclosure practices.

The controversy began to unfold when reports emerged of a significant data breach, impacting a staggering 33.7 million customers. Coupang's response and subsequent actions have left investors and the public questioning their commitment to cybersecurity and ethical business practices.

But here's where it gets controversial...

The lawsuit alleges that Coupang may have misled investors about the strength of its cybersecurity protocols, particularly regarding former employees. It also questions the effectiveness of Coupang's disclosure controls, suggesting they may have failed to ensure timely updates to investors about material cybersecurity incidents.

And this is the part most people miss...

On November 30, 2025, Reuters reported Coupang's apology for the breach, which triggered a series of events. The South Korean government held emergency meetings to investigate potential data safety rule violations. As the fallout intensified, Coupang's CEO of its South Korean e-commerce unit resigned, and police raided Coupang's offices in Seoul. The breach was allegedly caused by a former employee who retained access credentials, and Coupang's interim report confirmed their awareness of the incident on November 18, blaming it on this ex-employee.

Since the initial Reuters article, Coupang's market capitalization has plummeted by over $8 billion. The question remains: Did Coupang act promptly and transparently, as required by the SEC?

A Focus on Transparency and Investor Protection

Hagens Berman, a national shareholders rights firm, is leading the investigation into these allegations. They urge investors who have suffered substantial losses to come forward and provide their details. The firm also encourages individuals with knowledge of the situation to contact their attorneys.
