In a recent cybersecurity disclosure, Itron, Inc. confirmed that an unauthorized third party accessed parts of its internal IT network during a cyberattack.
The company detected the activity on April 13, 2026, and immediately activated its cybersecurity response plan. It also notified law enforcement and engaged external advisors to investigate, contain, and remediate the incident, according to a filing with the U.S. Securities and Exchange Commission.
Itron stated that the unauthorized activity has now been blocked, with no signs of further intrusion. The company also noted that there has been no material disruption to business operations and no immediate expectation of additional impact.
