The National Institute of Information and Communications Technology (NICT), a government research institute, reported on Feb. 27 that the average number of cyberattacks on each device connected to the Internet in Japan in 2017 was a record 560,000 times, or 1.2 times that of the previous year. With the spread of IoT devices, security cameras, cell phone routers, and so forth accounted for over 50% of cyberattacks.


The NICT has been collecting data relating to cyberattacks since 2005. Its surveys calculate the number of cyberattacks for each of the 300,000 IP addresses under observation.


Dominant among the attacks in 2017 were those targeting the vulnerabilities of small devices, such as cell phone routers. While past cyberattacks used to take advantage of gaping vulnerabilities, such as simple passwords, the techniques of attack have become more sophisticated.


Users tend to have little awareness that their devices are connected to the Internet, so security measures for certain devices are inadequate. The NICT predicts that the attackers will continue to change their tactics in 2018.
