(Tokyo Shimbun: February 18, 2015 – p. 3)
The number of cyber attacks on government, companies, and other organizations detected in Japan doubled in 2014 from about 12.88 million in 2013 to a record 25.66 billion, the National Institute of Information and Communications Technology (NICT) said on Feb. 17. The sharp increase indicates the increase in attacks in cyberspace.
The government plans to adopt “a cybersecurity strategy” at a cabinet meeting in June to bolster Japan’s defense against cyber attacks and promote international cooperation to deal with the sharp rise in cyber attacks.
To conduct the survey, NICT used about 240,000 sensors, including sensors that directly detect cyber attacks on companies and universities and sensors that indirectly detect cyber attacks on government organizations. NICT first conducted a survey on cyber attacks in Japan in 2005 when the number of such incidents stood at around 310 million. The number rose to about 5.65 billion in 2010 and to 7.79 billion in 2012.
Most of the cyber attacks were aimed at remotely controlling systems connected to the Internet. There were also cyber attacks that tried to check the vulnerability of software used in servers.
In an increasing number of cases, hackers took control of routers, security cameras, and other non-computer systems and used them to establish their own communications, NICT said.
Among countries for which the perpetrators’ IP addresses were traced, China accounted for the largest portion at 40%, while South Korea, Russia and the United States also ranked high.
