[Dispatch=Lee Myung-joo Reporter] SM Entertainment has suffered personal information leakage of its employees and executives due to a hacking incident.

On the 8th, SM posted a popup notice on its homepage regarding the hacking of in-house work systems (such as electronic approval systems) and the leakage of employee and executive personal information.

During an internal security monitoring process, the company discovered that some document files had been leaked by external attackers. The damage occurred around the 4th.

The leaked items include employees' names, mobile phone numbers, addresses, account numbers, resident registration numbers, department affiliations, positions, titles, and information contained in contracts.

SM stated, "We are conducting a thorough investigation with relevant authorities regarding the exact circumstances of this incident," and said, "We sincerely apologize for any concern caused by this accident."

Similar damage was also reported at affiliated companies. Hacking occurred at DearU, the operator of the fan communication platform "Bubble," and DreamMaker, a concert planning company.

The three companies blocked the IP addresses and access routes used in the attack immediately after becoming aware of the incident. They also prevented additional attacks by replacing unauthorized access keys.

No secondary damage cases have been confirmed so far. However, the companies emphasized caution against voice phishing or smishing involving impersonation of the company or related parties.

SM stated, "We will further strengthen access control and security monitoring of in-house systems. We will make efforts to prevent similar incidents from recurring."
