29CM Leaks 159,000 Customer Records... "Beware of Secondary Damage"

138,841 Cases of Name-Only Data Leaks

"Payment Information Was Not Compromised"

Muinsia's fashion and lifestyle platform, 29CM, has experienced a personal information leak affecting more than 159,000 customer records.

According to the industry on August 31, 29CM announced that on August 27, there was an abnormal external access to the API function for checking order information, which resulted in the leakage of some customers' personal information.

Specifically, there were 138,841 cases in which only the customer's name was leaked, and 21,011 cases in which the customer’s name, email address, mobile phone number, and shipping information were all leaked.

29CM explained that as soon as the issue was identified, it blocked the access path and voluntarily reported the personal information leak to the Korea Internet & Security Agency (KISA). In addition, the company notified affected customers of the specific items leaked and provided guidance on how to prevent secondary damages. A page where customers can check the details of the leak will also be operated for 30 days.

29CM stated, "Payment information and customer account information such as user IDs and passwords were not included in the leaked items and remain securely protected."

Nevertheless, 29CM urged customers to take precautions against the possibility of secondary damage from the leaked personal data. "Please be alert for any text messages, phone calls, or emails mentioning order details and providing payment, refund, or delivery error notices," the company emphasized.

The company also recommended that if you use the same password for other websites, you should change it, and if any personal information is included in delivery requests, you should modify it immediately.

29CM expressed, "We sincerely apologize for causing concern to our customers," and stressed, "We will thoroughly re-examine our security systems and management practices to further protect your valuable personal information."
