Difficulty of “preventing recurrence” from the viewpoint of cyber attack

An unprecedented communication accident caused by KDDI, I also suffered direct damage.


Announcement of “full restoration” at 15:36 on July 5, during the proofreading of this paper (https://www.nikkei.com/article/DGXZQOUC04BRD0U2A700C2000000/)had. In fact, 86 hours after the outbreak, the situation could not be settled for more than three and a half days. It’s an unprecedented situation.

First, the University of Tokyo Philosophy Deliberative Democracy announced in the previous serieshttps://mitsishikawa.wixsite.com/musicmanufacture/jukugi20yugi8) The ZOOM remote delivery address could not be sent by e-mail to the applicant.

I had no choice but to attach the URL of ZOOM on the portal site in a form that looks like an unspecified number of people, but there was almost no access from the person who made the reservation, which caused inconvenience.


The reason why the email could not be sent is that in order to access the entrance management email address, it is necessary to enter the confirmation code sent to the mobile phone with double approval, which is the mobile phone of au and KDDI. It was a situation where I couldn’t connect to other internet.

To make up for this, we plan to disseminate information this Saturday at the philosophical deliberation on July 9.

In this philosophical deliberation, the Japan Private Education Council (https://www.private-education.org/) The following 10 organizations conducted an academic survey on awareness of educational reform in preparation for the age of AI, conducted for members of the National Assembly of both Houses of Councilors and candidates for horses elected to the House of Councilors.https://www.schweitzerstreamm.com/enquete) Interim results will be announced.

We, the University of Tokyo faculty volunteers, cooperate in the design and analysis of academic surveys in consultation with related parties such as the Private Education Council and the Private University Association.

Unfortunately, the situation surrounding education in Japan is so severe that it can be said to be “desperate,” and according to the secretariat, the collection rate of questionnaires sent to members of the national assembly is still low.

We have nothing to do with political activity in the academic sector and are not committed to being involved in winning individual candidates.

However, the high response rate for each political party is an objective survey result, so we are thinking of disclosing it as it is.

In other words, the current politics is “indifferent to education”, and as a result, the “lost 30 years” could become the “lost 40 years” and even the “lost life” in 2030. do not have.
