Key Points

American energy technology company Itron confirmed in an SEC filing late Friday that it suffered a cyberattack in mid-April, with hackers gaining access to some of its internal systems. Itron provides smart metering and energy management services for water, electricity, and gas to over 110 million homes and businesses globally, making it a critical energy infrastructure supplier.

Timeline of Events

According to the SEC filing, Itron said it was “notified” of an intruder in its systems but did not specify who provided the notification. The company subsequently expelled the hackers and has seen no signs of further intrusions into its internal systems.

Itron did not specify the type of cyberattack it experienced — such as whether ransomware was deployed or if the company had been contacted by the hackers directly. It is also not immediately clear what impact, if any, the cyberattack is having on the company’s operations.

Customer Systems Not Affected

Itron stated that it did not identify unauthorized activity in the “customer-hosted portion of its systems,” suggesting that the breach may be limited to its IT network and has not compromised client infrastructure.

Emergency Response

Itron activated its contingency plans and data backups, and said its operations have “continued in all material respects.” However, the company warned that it may need to make subsequent legal filings and regulatory notifications. This suggests the company may have experienced a data breach, which could trigger further legal obligations under state data breach notification laws.

About Itron

Based in Liberty Lake, Washington, Itron provides technology for managing energy grids, including water, gas, and electricity supplies. The company has operations in over 100 countries and serves thousands of customers, including cities and municipalities.

Cybersecurity Accountability in Question

It remains unclear who at Itron is responsible for cybersecurity. A spokesperson for Itron did not immediately respond to TechCrunch’s request for comment.

The incident raises renewed concerns about cybersecurity at critical infrastructure providers. As a core technology supplier managing US energy and water systems, a breach at Itron carries potentially widespread security implications.
