Nikkei Asia: Japan’s power grid at risk via 100 million home devices

Japan’s power grid is exposed to hackers through roughly 100 million internet-connected home devices, Nikkei Asia reports today. The scale of the attack surface raises the risk of cascading disruptions if criminals or state-backed actors compromise weak consumer hardware and leverage it against grid systems. It underscores mounting cyber pressures on critical infrastructure as utilities digitize operations and households rapidly adopt connected gear.

Nikkei Asia says the vulnerable pool spans common home IoT and networking equipment, creating potential footholds for lateral movement or coordinated traffic floods that could strain power providers. Nikkei Asia highlights the urgency of tightening device security standards and segmenting networks to blunt intrusion risks. Watch for responses from Japan’s industry ministry and major utilities, and any new guidance on IoT hardening and grid cyber defenses. [Developing. This article will be updated.]
