Customers using the telco network at 11 a.m. Monday could not access the internet for about 40 minutes.

During that time, users were unable to use credit cards, exchange shares, or access online applications. It also appears that some major commercial websites were shut down during the shutdown.

Since then, general internet access for KT users in most parts of the country has been restored.

A KT spokesman said the network had collapsed due to a large-scale DDoS attack and that during the outage, the company's crisis management team was in a hurry to restore the network to normal operation.

At the moment, KT does not know the extent of the damage or who carried out the DDoS attack, the KT spokesman added.

Federal police said they were working with KT. Authorities did not confirm that the network outage was caused by a DDoS attack, but said the other major telecommunications companies, SK Telecom and LG Uplus, were not affected.

Although there were no victims of the DDoS attack, the users of the services SK Telecom and LG Uplus expressed their complaints on social media, commenting negatively on the telcos that faced such problems. Representatives of these telcos said that the network failures were due to the sudden increase of traffic by KT users who have been relocated due to the interruption of KT internet.
