About Leviton Founded in 1906 and headquartered in Melville, New York, Leviton is a privately held global provider of electrical wiring devices, data center connectivity solutions, and lighting energy management systems. A major cyber attack has resulted in the Leviton company losing control over its entire repository of sensitive data, totaling approximately 1.4 terabytes. The massive breach exposed a wide range of highly confidential information, including internal financial records, proprietary project schematics and working documents, as well as the personal data of employees. Additionally, a significant quantity of other unclassified but highly sensitive information was exfiltrated in the breach, painting a stark picture of a total system compromise.
