Wuri Investment Securities sent some customers an incorrect text message about the cooling-off period for high-risk financial products, raising controversy over potential personal data exposure and weak internal controls. The company said an error occurred during a sending test and the content was unrelated to actual customers.

The financial investment industry said on June 9 that Wuri Investment Securities sent a "cooling-off period notice" text message to some customers on June 8. The message included a specific customer name and information related to an application to subscribe to the Hanwha 2.2x Leverage Index Securities Investment Trust.

The message included the purchase application date of June 8, 2026, the cooling-off period of June 9 to 10, 2026, and the period to confirm intent to subscribe of June 11, 2026. It said customers must decide whether to subscribe after sufficiently reviewing product risks during the two-business-day cooling-off period, and that subscription would be automatically cancelled if intent was not confirmed directly within the confirmation period.

It also provided video reference materials and key precautions for high-risk products. It said the product is a performance-linked dividend product in which profit and loss are determined by changes in market and underlying asset prices, and that invested principal is not guaranteed and losses may occur. It also said the maximum possible loss of principal could be the full amount invested and that profit and loss from the investment belongs to the investor.

Wuri Investment Securities later sent a correction text on June 9, saying, "The 'cooling-off period notice' text sent the previous day was mistakenly sent due to an error during a sending test." It added, "As this is unrelated to you, we ask for your understanding," and said, "We are sincerely sorry for any inconvenience."

The incident is drawing attention because it could go beyond a simple mistaken text message and lead to potential personal data exposure. Customers apparently unrelated to the application received what appeared to be another person's name and a schedule related to subscription to a financial product.

It could also put internal controls under scrutiny. Messages providing information on financial investment products can include sensitive information such as customer names, product names, subscription schedules and investment risk notices, making pre-send review procedures important.

In particular, if a test message was delivered to actual customers, some are pointing to the need to check whether test account management, sending approval procedures and systems blocking sending to real customers worked properly.

The cooling-off period system is a procedure that delays a subscription decision for a set period so that investors seeking to subscribe to high-risk financial investment products can sufficiently review product structures and risks. It operates as an investor protection measure for products with a high possibility of loss, such as leveraged products.
