[Alpha Biz= Paul Lee] Seoul, South Korea — An incident occurred on December 2 in which Meritz Securities’ mobile trading system (MTS) displayed other customers’ U.S. stock trade information to certain users.

According to industry sources, shortly after the close of the U.S. market this morning, some users of the Meritz Securities MTS application received push notifications showing another client’s U.S. stock execution details.

The alerts reportedly included the customer’s name, traded stock, execution time, and purchase price, all displayed without redaction.

Meritz Securities stated that the incident was caused by a simple notification-sending error, emphasizing that it was not related to hacking, data breaches, or any unauthorized access to personal information.
