Itron discloses April cyberattack on corporate IT systems — utility tech supplier used across critical infrastructure in 100+ countries

Itron, a utility technology supplier whose systems are used by more than 100 countries for smart metering and grid management, disclosed on 28 April 2026 that attackers accessed its internal corporate IT systems in April, detecting and blocking the intrusion before further activity occurred. The disclosure is significant because Itron’s platforms intersect with critical infrastructure in water, gas and electricity management — sectors that interface directly with emergency services and policing of critical infrastructure. Forensic review must verify segmentation between corporate systems, customer platforms and operational technology dependencies. The incident follows a pattern of corporate IT intrusions at critical infrastructure suppliers used as a stepping stone toward OT network access. For law enforcement investigating infrastructure attacks, the Itron disclosure adds to the documented threat landscape for utility sector targeting in 2026.
