Over 4,700 cyber attacks over 5 years by the Ministry of Land, Infrastructure and Transport and affiliated organizations... 1 out of 3 locations are not connected to the security system

The Ministry of Land, Infrastructure and Transport has the highest number of cases at 766... Real Estate Agency 655 cases, KORAIL 579 cases

(Sejong = Yonhap News) Reporter Oh Jin-song = More than 4,700 cyberattack attempts targeting the Ministry of Land, Infrastructure and Transport and its affiliated organizations have been detected over the past five years.

However, 11 of the 31 public institutions under the Ministry of Land, Infrastructure and Transport were found to be not linked to the national security control system.

On the 6th, as a result of analysis of data received from the Ministry of Land, Infrastructure and Transport by Rep. Jo In-cheol of the Democratic Party of Korea, a member of the Land, Infrastructure and Transport Committee of the National Assembly, a total of 4,778 cyber attack attempts were detected by the Ministry of Land, Infrastructure and Transport and affiliated organizations to which the national security control system was applied from 2021 to 2025.

By year, there were approximately 800 to 1,000 attempted attacks each year: 1,021 in 2021, 989 in 2022, 812 in 2023, 1,019 in 2024, and 937 in 2025.

By attack type, 'homepage forgery/falsification' (web vulnerability) type was the most common with 2,609 cases (54.6%), followed by 'simple intrusion attempt' with 1,902 cases (39.8%). The two types accounted for 94.4% of the total. This is not the number of actual homepage modifications or breaches, but the number of detected cyberattack attempts of this type.

By agency, cyber attack attempts against the Ministry of Land, Infrastructure and Transport accounted for the most with 766 cases. Among affiliated organizations, Korea Real Estate Agency had the most cases with 655 cases, followed by Korea Railroad Corporation with 579 cases, Land, Infrastructure, Transport Science and Technology Agency with 557 cases, and Korea Expressway Corporation with 461 cases.

In particular, cyberattack attempts against SR, which was integrated with the Korea Railroad Corporation last September, increased approximately 7.6 times in five years from 23 in 2021 to 175 in 2025.

Although cyberattack attempts are continuing, as of last month, 11 out of 31 public institutions under the Ministry of Land, Infrastructure and Transport (35.5%) were not linked to the national security control system.

The non-linked organizations are Gadeokdo New Airport Construction Corporation, Construction Technology Education Institute, Spatial Information Industry Promotion Agency, Spatial Information Quality Management Agency, National Aviation Museum, Automobile Insurance Promotion Agency, KORAIL Tourism Development, KORAIL Logis, KORAIL Tech, Korea Expressway Corporation Service, and Korea Overseas Infrastructure and Urban Development Support Corporation. Representative Cho's office explained that these organizations have prepared a plan to link national security control, but actual implementation is delayed.

Rep. Cho said, "The state of one out of three affiliated organizations not being linked to the national security control system should not be prolonged for a long time," and added, "The Ministry of Land, Infrastructure and Transport should closely inspect the budget, human resources, and system conditions of the unlinked agencies and provide necessary support so that the currently prepared linkage plan can lead to actual construction."
