Spiral LOCAS: unauthorized access to the municipal staff call-up system

On October 22, Akiruno City disclosed unauthorized access to its account on a staff call-up system operated by Spiral LOCAS. Staff names, employee numbers, departments, passwords and emails leaked; resident information was excluded. The city requested investigation and prevention measures. Chunichi reported that the attacked staff-safety service was used by two municipalities; the company's roughly 650 municipal customers are not a count of affected municipalities. No affected-record count was published.
