Seoul: South Korea's fifth-largest card issuer, Lotte Card, announced that a cyberattack last month resulted in the compromise of personal information for approximately 3 million customers. The company confirmed this breach on Thursday.

According to Anadolu Agency, hackers managed to steal around 200 gigabytes of data, which included identification numbers, internal IDs, and contact information. While there have been no reports of misuse so far, concerns have been raised due to the breach of sensitive financial information. Approximately 280,000 customers had their card numbers, verification codes, and expiration dates compromised, which could potentially lead to credit card fraud.

Lotte Card CEO Cho Jwa-jin issued a public apology and assured customers of full compensation for any damages incurred. He disclosed that the breach took place between July 22 and August 27 during online settlement processes.

In recent months, South Korea has experienced several data breaches. In July, a luxury brand suffered a cybersecurity incident, and the government fined a telecom firm for a separate breach. Earlier this year, brands like Dior and Tiffany and Co. also reported data leaks. In one of the largest cyberattacks in the country's history, SK Telecom disclosed in April that the personal data of more than 20 million users had been compromised.
