[Asia Economy Reporter Ki Ha-young] It has been confirmed that approximately 900,000 domestic credit card information records were leaked on the dark web. The dark web is an internet black market that allows users to avoid IP tracking. Card companies plan to notify their members of the card information theft via email and text messages, and they intend to fully compensate for any amounts used with the illegally distributed card information.


According to the Credit Finance Association on the 9th, the Financial Security Agency recently confirmed, based on information from an overseas private security firm, that about 900,000 domestic card information records have been illegally traded on the dark web from January 2015 to last month. Excluding cases where the cards are no longer valid due to expired expiration dates or reissuance, approximately 410,000 cards are currently valid. The leaked information includes card numbers and expiration dates. The association stated that password information was not leaked.


The association explained that they have already confirmed the card information theft and reflected it in the Fraud Detection System (FDS) to block approval of fraudulent use. Card companies plan to fully compensate for any fraudulent use incidents to ensure that card members do not suffer direct damages.



Card companies will notify members of the card information theft via email and text messages. If fraudulent use is detected, they will send phone calls or texts and block approval. An association official said, "It appears that the information was hacked through POS terminals infected with malware before the introduction of IC terminals," adding, "Currently, IC terminals with enhanced security certification are mandatory, so there is no additional risk of information leakage."
