The Nuclear Material Control Center released the results of its internal inquiry on May 18 regarding an incident whereby data was leaked from file-sharing software that had been installed onto an employee's personal computer.
The center, a public interest incorporated foundation that is responsible for conducting nuclear-related inspections on nuclear power and other facilities, revealed that the center's server was separately accessed illegally last year in February -- and was subsequently utilized as a type of springboard from which to conduct cyber-attacks on outside computers.
According to the center's report, the illegal access occurred as a result of defects in the server's security -- and has already been corrected following a warning from an external agency.
However, the center did not report this matter to the secretariat of the Nuclear Regulation Authority until April this year -- thereby flouting its own internal regulations by not reporting the problem when it was first discovered.
Regardless, because the file-sharing software was used only on one single employee computer, the center has said that the possibility that sensitive information was leaked is low.
