An overnight system failure occurred on Kiwoom Securities' mobile trading system (MTS), causing inconvenience for investors in stock transactions.

According to the financial investment industry on the 7th, on the night of the 6th a connection error occurred on Kiwoom Securities' MTS "Hero M S#." Users said that when they tried to access Hero M S#, a reboot occurred along with a message reading "Scrpt error reported."

As the New York stock market plunged overnight on the back of weak jobs data, the MTS error magnified investor inconvenience.

Kiwoom Securities explained that a program defect in Hero M S# caused access disruptions for some customers. A Kiwoom Securities official said, "Measures have now been completed, and we guided users to the overseas stock app 'Hero M SG' and the home trading system (HTS) to ensure there was no disruption to transactions."

Meanwhile, the Kiwoom Securities MTS error also occurred in April this year. After the large-scale order error incident in April, Kiwoom Securities said it strengthened related personnel and organizations and would invest an additional 30 billion won in the related services within the year.
