The number of leaked items also increased from 17 to 39. The balance of deposits, loan transaction details, and credit ratings were included.Kookmin Bank announced on the 26th that it confirmed the leakage of information of 2,091 additional people as a result of a detailed analysis of existing infringement accidents with supervisory authorities and related agencies. Additional targets include 1,631 customers and 460 executives and employees. If the initial confirmation (99 customers and 20 executives) is added, there are 1730 customers and 480 employees. The scope of damage has been greatly expanded in 24 days since the first announcement on the 2nd.Kookmin Bank said no new hacking attack took place. It is explained that additional leaks were confirmed while precisely re-verifying the data and business process of the accident system.The accident occurred due to an external attack targeting a mobile work support system for employees. According to data submitted by Park Min-gyu, a lawmaker of the Democratic Party of Korea, from the night of the 27th of last month to the afternoon of the 29th, the attack lasted about 43 hours. Kookmin Bank identified the attack at around 7 p.m. on the 30th of last month.Customer leakage items included name, date of birth, encrypted resident registration number, address, and phone number. Annual income, deposit balance, account number, loan transaction details, credit card delinquency principal, credit rating, and whether or not to apply for workouts were also leaked. However, Kookmin Bank said that most of the customers have about four outflow items, and each customer has a difference.Kookmin Bank plans to individually guide additional customers on the leak and how to prevent secondary damage, and compensate them in full if secondary damage occurs. Next year’s information protection budget will be set at more than 100 billion won, up from 86 billion won this year.Criticism of the banking sector’s information protection system is also growing due to a series of hacking incidents in the financial sector. Previously, the five major bank presidents appeared as witnesses to the National Assembly’s parliamentary audit for the first time in four years and were criticized for poor security management. An official from Kookmin Bank said, “We sincerely apologize for not being able to fully grasp the extent of the damage at the beginning,” and added, “We will do our best to prevent recurrence and protect customers.”As several financial companies have been hacked at the same time, there are concerns that other companies may belatedly reveal additional leaks.On this day, it was reported that the first infringement occurred in the insurance industry. Mirae Asset Life Insurance confirmed the leakage of personal information through analysis with external specialized institutions after checking the abnormal symptoms of some systems on the 25th. Infringement accidents occurred in part of the customer subscription system and website.Mirae Asset Life Insurance said it has strengthened security measures by operating an emergency response system and blocking the attack IP to prevent further damage. The exact targets and items of the leak are being identified. The Financial Supervisory Service, which conducted an on-site inspection of Mirae Asset Life Insurance on the 27th, plans to switch to an official inspection if any of the above regulations are found during the inspection process.
