Tokyo, Sept. 26 (Jiji Press) — The number of suspicious access to Internet Protocol addresses confirmed per day in Japan in the first half of 2019 came to 3,530.8 per address, up 58.8 pct from a year before, the National Police Agency said Thursday.
Many of the cases targeted Internet of Things devices, including consumer electronics. According to the agency, suspicious activities that cannot be anticipated in ordinary Internet use, such as those apparently related to attempts to conduct cyberattacks, are on the rise.
Cases of suspicious access targeting an imported Blu-ray Disc recorder and other devices connected to the Internet were newly discovered in and after June this year.
“There is a high possibility that these attacks were aimed at abusing the vulnerability of IoT devices to spread malicious programs,” an NPA official said. “We want people to keep in mind to update their software for strengthening security.”
Meanwhile, the number of targeted email attack cases, in which messages carrying viruses are sent to businesses and others with an attempt to steal important information, came to 2,687 in the first half of the year, up 4.2 pct.
Of the email addresses targeted by such attacks, 82 pct were not publicly available online, while 90 pct of the addresses used by the senders were fake.
