Analysis results showed that the nationwide KT network failure that occurred on the 25th was not a DDoS attack, but an error caused by a omission of operator commands during the router replacement operation.

At 3 pm on the 29th, 2nd Vice Minister of the Ministry of Science, ICT and Future Planning Cho Kyung-sik announced the results of the KT network failure analysis held at the Government Complex in Jongno-gu, Seoul, saying, “As a result of analyzing IP patterns, etc., it is not a DDoS attack.” The failure caused by setting the wrong configuration command caused a nationwide network error.”

Vice Minister Cho explained, “It was conducted during the day, not at night, and without a KT task manager, the employees of the subcontractors worked together.

According to the results of analysis by the Ministry of Science and Technology together with information protection and network experts, on the 25th, KT communication failure occurred at 11:16 a.m. on the same day without a KT supervisor. While inputting information, an operator mistakenly omitted the ‘exit’ command for the IS-IS protocol that exchanges data path information between internal router devices. Because of this, the script was not completed and connected to other scripts, and the nationwide network was linked in the form of ‘automatic update’, causing the nationwide network to go down.

Regarding the work being done during the day instead of night work, Vice Minister Cho said, “The change in working hours was not a decision made by the supplier alone, but was made in consultation with KT. explained.

Vice Minister Cho said that the Ministry of Science and Technology will take this seriously and will establish reinforced measures such as preparing a monitoring system.
