People working from home due to the novel coronavirus pandemic may want to think twice about consulting the National Police Agency about computer security.
The agency failed to stop hackers from breaking into one of its personal computers 46 times between August 2019 and mid-November this year, red-faced officials announced on Nov. 27.

The Asahi Shimbun analyzed the list with the help of outside experts and found 5,600 IP addresses in Japan were on it. The number was second only to the 7,700 or so IP addresses in the United States.
Identifying the organizations possessing the IP addresses led to small businesses, local governments and educational institutions in Japan.
One of the educational institutions was Sapporo University in Hokkaido, which on Dec. 4 announced that the ID information of nine employees had been stolen by hackers.
The VPN devices on the list were all manufactured by Fortinet of the United States. In May 2019, the company announced a…
