Park Dae-Jun-Jun has resigned as the Chief Executive of South Korea Retail Geanant Complete a Data Breach that is related to half of the country’s population.

In a statement, Park apologized for the offense, citing a “deep sense of responsibility for the explosion and the subsequent recovery process.”

Coapa replaces Park in Harold Rogersthe top lawyer of the company based on the US-based parent, according to a machine translation of the company statement.

The retailer giant, which is often compared to Amazon for its dominance of South Korean e-commerce and logistics, last month revealed details of a data breach that affected nearly 34 million people. The breach is said to have started in June but was not noticed until November, when Coapang said more than 4,500 customers had their data stolen. The company later changed the number above.

Hack Hack is the latest in a string of security incidents affected corporate giants and the central government across the country this year, including a data center fire that led to a massive, irrevocable loss of South Korean government data.
