INCIDENT

A pro-Russia hacker group has claimed to be involved in attacks on Japanese government and company websites.

The DDoS attack on the e-Gov website shut down the site for a few hours on Sept. 6. It then became inaccessible again around noon on Sept. 7 until early morning, Sept. 9. The e-Gov website allows users to request disclosure of administrative documents and provides information on laws and regulations. The site receives about 7.8 million hits a day.

In addition, between Sept. 6 and 9, the attacks made 23 government websites temporarily inaccessible. These sites belonged to the Digital Agency, the Internal Affairs and Communications Ministry, the Education, Culture, Sports, Science and Technology Ministry and the Imperial Household Agency. Some sites of credit card business JCB Co. were inaccessible, while websites of social media company mixi, Inc. were also hard to access.

On September 6, 2022, the website of the Nagoya Port Authority was unreachable for about 40 minutes.
