- Itron reports a cyber attack that briefly affected parts of its IT network but did not cause any significant disruption
- The company activated its response plan, blocked the intrusion and said sensitive data and customers were not affected
- With the investigation underway, Itron expects any costs to be covered by insurance, and no hacker groups have claimed responsibility
US utility technology giant Itron has confirmed that it recently suffered a cyber attack in which threat actors gained access to parts of its IT network – although sensitive data appears to be safe.
In an 8-K form filed with the US Securities and Exchange Commission (SEC), the company said it discovered the breach on April 13, 2026.
“The company activated its cybersecurity response plan and initiated an investigation with the support of outside counsel to assess, mitigate, remediate and limit the unauthorized activity,” the filing said.

Itron did not say who the threat actors were or how they were able to break into its network. It simply stated that the attack was blocked and that there was no follow-up activity on the part of the threat actors.
The US-based company provides smart meters, sensors and data platforms to utilities and cities, which are then used to manage electricity, gas, water and other systems. Itron serves more than 8,000 utilities across 100+ countries, reaching hundreds of millions of people and generating approximately $2.4 billion in annual revenue.
Bleeping Computer notes that it employs about 5,600 people and is listed on the NASDAQ stock exchange.
Critical infrastructure organizations are one of the more popular targets for ransomware operators, who aim to either lock down systems or steal sensitive files.
This gives them leverage as they demand a ransom to be paid. In this attack, however, Itron said there was no significant disruption and that any costs incurred as a result of the incident will be covered by insurance.
Itron added that its customers were not affected by the attack, but stressed that the investigation is still ongoing. At press time, no hacker groups had claimed responsibility for the attack, and given that the impact was likely to be minimal, no groups are likely to do so.
