American energy technology firm Itron confirmed on Friday that it suffered a cyberattack in mid-April, resulting in unauthorized access to certain internal systems. The disclosure came via a mandatory filing with the U.S. Securities and Exchange Commission late in the day. According to the report, Itron was notified of the intruder and subsequently expelled the attackers. The company stated there are currently no signs of further intrusions within its internal environment. While the specific nature of the attack remains unclassified, Itron did not indicate whether ransomware was used or if the perpetrators made direct contact with the organization. It is also unclear if the incident has significantly impacted the company's operational capabilities. However, the filing suggested that the breach was likely confined to the IT network, as Itron found no unauthorized activity within the customer-hosted portion of its systems. Itron, based in Liberty Lake, Washington, is a critical infrastructure provider offering solutions to manage energy consumption across water, gas, and electricity grids. The company supplies internet-connected utility meters to over 110 million homes and businesses globally. With thousands of clients ranging from cities and municipalities to international operations in more than 100 countries, the security of its systems is of paramount importance. Upon discovering the breach, Itron activated its contingency plans and relied on data backups to maintain business continuity. The company assured stakeholders that operations continued in all material respects. Nevertheless, Itron warned that it may need to submit additional legal filings and regulatory notifications in the future. This statement implies that a data breach involving customer information may have occurred, which could trigger mandatory reporting requirements under various state data breach notification laws. The specific individual or department responsible for cybersecurity at Itron has not been identified in the report. When contacted by TechCrunch regarding the incident, a company spokesperson did not immediately provide a comment on who is overseeing cybersecurity measures or the full extent of the breach investigation. Itron has also notified law enforcement authorities regarding the cyberattack. The situation remains under review as the company evaluates potential long-term impacts and compliance obligations.
