A tweet purporting to be from Anonymous, a diffuse international collective of online hacker activists, warned of cyberattacks on the websites of two major airports earlier this month, police sources said Saturday. A day later, the web pages of Narita and Chubu airports were struck down.
On Oct. 10, the website of Narita International Airport went down for about eight hours from around 2:30 a.m. after being overwhelmed by multiple-source traffic.
The website of Chubu Centrair International Airport also became difficult to access for 8½ hours.
Flights at the airports were unaffected.
