[Notice] Security Incident Notification and Apology

POLYCLUB LIMITED (POLYTRIPS)

Dear Valued Customers,

We have always made every effort to protect your personal information. However, we have recently identified signs of unauthorized access and intrusion from an external source.

We sincerely apologise for any concern this incident may have caused.

Immediately upon detecting the incident, we blocked the affected server and implemented emergency security measures. We are currently working with relevant authorities to investigate the exact cause and scope of the incident.

■ Incident Overview and Response

  • Time of Detection: April 19, 2026, approximately 09:46 AM (KST)
  • Estimated Time of Intrusion: April 18, 2026, approximately 11:41 PM (KST)
  • Details: Signs of unauthorized server access due to an external intrusion (currently under investigation)
  • Actions Taken: The affected server was immediately isolated and external access was blocked upon detection. The incident has been reported to relevant authorities, and an investigation is currently underway.

■ Service Availability

To strengthen security, login and certain functions are temporarily restricted.
However, cruise booking and reservation lookup services remain available.

■ Potentially Affected Information

We are currently conducting a detailed investigation with law enforcement authorities and security experts. Based on our findings so far, we cannot rule out the possibility that certain personal data may have been accessed.

  • Email address
  • Name, phone number, and date of birth (for some customers)
  • Address (for some customers)
  • Passport number (for some customers; no additional details such as expiry date were included)

※ The types of information involved may vary by customer, and it has not yet been confirmed which specific data, if any, was accessed for each individual.

■ System Security Information

  • Passwords: Stored using one-way encryption (hashing), making it impossible to retrieve the original values by us or any external party
  • Booking Information: Cruise booking data is managed directly by each cruise line’s system and is operated separately from our platform. Therefore, it remains secure and unaffected by this incident.

■ Customer Precautions

If you are using the same password across multiple services, we recommend changing it as a precaution.

Please remain cautious of emails, messages, or calls from unknown sources.

POLYTRIPS will not initiate contact to request your reservation number, payment, or installation of applications related to this incident. Please be cautious of impersonation attempts.

■ Contact Information

POLYTRIPS takes this matter very seriously. We will continue to cooperate with the relevant authorities to identify the cause and take all necessary measures to prevent recurrence.

We once again sincerely apologise for any inconvenience and concern caused.
