General credit information system migration completed Oct. 5
Loans, cards, account openings running normally
CPU processing capacity up 3.2-fold; cybersecurity defenses reinforced
Korea Credit Information Services said Monday that its next-generation general credit information system, which completed its migration on Oct. 5, is operating stably. The upgrade boosted processing performance for core financial infrastructure used in everyday transactions — including loans, credit cards and account openings — and strengthened defenses against cyber threats.
The next-generation general credit information system went live at 8 a.m. on Oct. 5. Related services that had been temporarily suspended for the migration were restored at the same time, and the organization has since been continuously monitoring key functions and data processing.
The general credit information system is widely used by financial institutions for core operations such as lending, card issuance and account opening. Korea Credit Information Services conducted advance checks and migration rehearsals with a focus on minimizing disruption to financial institutions and consumers during the switchover.
Cybersecurity measures were also reinforced. In preparation for potential cyberattacks targeting the transition period, the organization reviewed and reduced potential attack surfaces — including external access points — in advance, and activated intensive monitoring before and after the system launch. It also raised its response level against anomalies and intrusion attempts.
The upgrade increased maximum transaction processing capacity, measured in transactions per second, by about 3.1 times compared with the previous system. CPU-based processing headroom improved 3.2-fold, laying the groundwork for faster responses to future changes in the financial environment.
Korea Credit Information Services has been building the next-generation system over roughly two years. It first launched the next-generation insurance and technology credit information system in February before completing the migration of the general credit information system.
"We are grateful to financial consumers for their patience during the system transition, and to the financial institutions and related organizations that cooperated to make the migration smooth," Korea Credit Information Services President Yu Su-yeong said. "In line with the era in which data and AI are driving innovation in the financial industry, we will fulfill our role as core financial infrastructure that financial institutions and the public can trust."
Meanwhile, financial authorities said they identified 33 IP addresses linked to recent hacking attempts targeting the financial sector, with 28 unique addresses after removing duplicates. The IP addresses used to attack commercial banks differed from those targeting savings banks and capital companies, but the attack methods were similar. Traces of a Chinese AI-based security scanning tool called ARTEX AI were also found. The Ministry of Science and ICT said it has activated a round-the-clock response system in preparation for further attacks.
