Peatix, which is a ticket service we used at TEDxUTsukuba in the past, attacked by a third party from October 16th to 17th, 2020. It was reported that up to 6.77 million personal information such as "name", "email address", and " password" have been extracted. (It seems that the fact that payment-related information such as credit card information and financial institution account information, event participation history, data acquired by the questionnaire form function for participants, address, telephone company, etc. was extracted has not been confirmed. It is said that other matters are currently under investigation. Please see the following URL for details.


The following events held by our organization used Peatix:
  • 2017 TEDxUTsukuba「moving」
  • 2016 TEDxUTsukuba「joyn’」
We apologize for any inconvenience caused by this incident. It is officially advised to change the passwords of other services that have the same passwords as Peatix.
