Japanese company Temairazu announced that it has confirmed unauthorized access to its system and that people who made reservations at accommodation facilities using the “TEMAIRAZU” series have been receiving suspicious messages related to their bookings.
Beginning around late night on September 21, multiple accommodation facilities reported that their guests had received suspicious messages via messaging apps such as WhatsApp, email, and SMS. The messages reportedly include information suggesting that the sender is aware of details of the accommodation reservation, and in some cases direct recipients to suspicious websites requesting them to confirm or finalize their reservation, re-enter credit card information, or make an urgent payment.
Temairazu believes that the suspicious messages may have resulted from the unauthorized access and is investigating the connection between the two incidents and the scope of the impact. The company said it cannot rule out the possibility that some guest information may have been viewed or obtained by a third party as a result of the unauthorized access.
After confirming the unauthorized access, the company implemented measures to prevent further damage, including blocking access, identified the cause, and completed countermeasures. It has also introduced security measures, including strengthened access controls and monitoring systems. Functions that had been temporarily suspended have resumed, and the system is currently operating normally.
Guests who receive suspicious messages are advised not to open the URLs or links provided, enter credit card or personal information, reply to the messages, or make payments or transfers in accordance with their instructions. Those wishing to confirm reservation details are advised to contact the official channels of the accommodation facility or booking website. Temairazu said that it does not handle or retain credit card information.
Accommodation facilities have been asked to change their TEMAIRAZU login passwords. Online travel agencies (OTAs) and partners connected to the system have been asked to check their administration screens for suspicious logins or changes to settings.
