Kanagawa Sewerage Public Corporation: BlackSuit ransomware on servers and PCs; personal data may have leaked

Kanagawa Prefecture announced on 10 October 2024 that the network system of the Kanagawa Sewerage Public Corporation, a prefecture-led third-sector body, had been infected and personal data may have leaked. At about 2:00 on 9 October a staff member at the Yanagishima water reclamation center noticed a PC fault, and the maintenance contractor confirmed at about 17:00 that a server and two PCs were infected with the BlackSuit ransomware. The server may have held school names and children's names from a calligraphy and painting contest, names and phone numbers of plant tour applicants, names, addresses, phone numbers and email addresses of event performers and exhibitors, and staff hiring and HR data. Sewage treatment plants kept running normally.
