Lotte Card said on the 13th that it has taken steps such as card reissuance, PIN changes, and card suspension and cancellation for about 230,000 (82%) of the 280,000 customers at risk of fraudulent use due to the leakage of sensitive information in a hacking incident.
About 220,000 of them applied for card reissuance, and reissuance has been completed except for some special cards. For the roughly 50,000 who have not received protective measures, the company will continue to guide them to reissue, and starting on the 15th, use of the affected cards at online merchants will be restricted.
Lotte Card said it has completed protective measures for about 1.46 million (49%) of the total 2.97 million customers whose information was leaked. Among those affected, about 778,000 had their cards reissued, about 920,000 changed their PINs, and about 180,000 had their cards suspended. About 56,000 canceled their cards, and about 30,000 closed their memberships.
From the 1st of last month, when the hacking incident came to light, through the day before, total reissuance applications reached about 1.21 million, of which 1.19 million (98%) were completed. Lotte Card said that once stock of blank cards was secured, card reissuance became available immediately upon application, except for some special cards.
Lotte Card added that it has not yet confirmed any attempts at fraudulent use or cases that led to actual consumer harm from this hacking incident, and that if sensitive information was not leaked, there is no possibility of fraudulent use.
