● Yes24 Official Apology for Ransomware Disaster
We sincerely apologize to our customers.
On June 9, 2025, Yes24 suffered a service interruption due to a ransomware attack by an external force, paralyzing the entire company’s system.
This has caused inconvenience and anxiety to customers, as important daily activities such as ordering books, reading e-books, and reserving performance tickets have been halted.
Yes24 feels the weight of this inconvenience more than anyone else.
We bow our heads in deep apology to all customers, partners, and everyone else who experienced inconvenience due to this accident.
Yes24 is a platform that has grown based on customer trust.
We take very seriously the fact that this accident has shaken that trust, and we are currently mobilizing all our capabilities to recover the damage and restore trust.
Accident details and recovery status
This incident is a system failure caused by an external ransomware attack, and Yes24, as a responsible platform operator, is putting all its efforts into service restoration and security inspection.
Immediately following the attack, Yes24 prioritized internal analysis and recovery while faithfully cooperating with relevant government agencies in their investigation.
We filed a proper report immediately after the incident occurred, but due to the special nature of ransomware attacks, hackers may monitor external reactions or make additional threats, so we had to be cautious about the level and timing of information disclosure to the public.We ask for your understanding.
However, we apologize again for not being able to provide accurate information to our customers more quickly and accurately.We will communicate more transparently and consistently in the future.
Core services such as purchasing books, records, stationery, eBook, ticket services, and order payments have been restored, and some additional services such as reviews are being restored sequentially with every effort.
Customer damage compensation and recovery measures
Yes24 has established compensation standards applicable to each service type for customers who have experienced inconvenience due to service interruption.
We plan to announce the first compensation plan today, and we will provide additional compensation plans through notices on the website.
Measures to prevent recurrence and strengthen security
Yes24 is cooperating with government agencies(KISA, Personal Information Protection Commission)and external security experts to investigate the cause of the accident and conduct security diagnosis, and will transparently disclose the results of the investigation by the relevant agencies.
We will also use this incident as an opportunity to reexamine our security system from the beginning.We will introduce an external security advisory group and expand our security budget to strengthen the reliability and resilience of the platform from system design to overall operation.
In addition, we will actively participate in discussions on improving systems to create a safer digital ecosystem in cooperation with the government and industry, and become a responsible company that fulfills its social role.
We promise to take full responsibility for this process to rebuild our customers’ trust.
Once again, we bow our heads in apology to everyone who experienced any inconvenience.
