Seoul: Lotte Card Co., the country’s fifth-largest card issuer, announced on Thursday that personal data of approximately 3 million customers was compromised in a hacking incident last month. Despite the breach, there have been no reports of improper use of the leaked data so far.
According to Yonhap News Agency, the compromised information includes identification numbers, internal identification numbers, and connecting information. Furthermore, card verification codes for around 280,000 customers have been breached, increasing the risk of potential misuse of the data.
Earlier this month, Lotte Card, which boasts a membership of about 9.6 million, revealed the occurrence of a cyber breach. Since the disclosure, both the financial watchdog and the card company have been working to assess the extent of the damage caused by the hacking incident.
The data breach at Lotte Card is the latest in a series of significant cyberattacks targeting the financial sector. Previously, Seoul Guarantee Insurance had also experienced a similar hacking event.
This cybersecurity lapse at Lotte Card comes amid calls from Financial Supervisory Service Governor Lee Chan-jin urging financial institutions to enhance their cybersecurity measures and improve the protection of customer information.
