In response to customer data breach incidents at major commercial banks, financial authorities have notified securities firms of hacking precautions and urged them to conduct self-inspections.
According to financial authorities and the financial investment industry on the 2nd, the Financial Services Commission distributed guidance materials containing hacking precautions to each financial institution, including securities firms, the previous day, and ordered them to conduct self-checks. A source at the Financial Services Commission stated, "We distributed materials detailing the types of intrusion involved in the Shinhan Bank incident, response methods for those types, and inspection items from the perspective of preventive precautions across the entire financial sector."
In response, securities firms have inspected their hacking prevention systems and checked for any customer data leaks. Mirae Asset Securities, NH Investment & Securities, Samsung Securities, Korea Investment & Securities, and KB Securities stated that they found no abnormalities after conducting self-inspections. It is also known that other securities firms are currently undergoing self-checks.
The financial authorities held a meeting on the afternoon of the 2nd to review hacking incident prevention measures in the financial sector and customer information protection systems. This comes as data leaks have occurred at KB Kookmin Bank following Shinhan Bank, prompting a review of the financial sector's response status.
In the banking sector, customer data breach incidents have occurred over the past two days. At Shinhan Bank, customer information for approximately 25,000 people was leaked due to a hacking incident on the 30th of last month. The leak occurred when hackers exploited security vulnerabilities in a simple inquiry service intended for loan solicitors. At KB Kookmin Bank, credit information for 119 customers was leaked due to a hack on the mobile business support system used by employees.
