A threat actor, Tsar0Byte, allegedly claimed to have breached Nokia’s internal network through the exploitation of a third-party contractor’s systems that had direct access to Nokia’s internal infrastructure, exposing sensitive data belonging to more than 94,500 employees. The breach is one of the largest corporate data exposures affecting Nokia in recent years, with compromised data including full employee names, corporate email addresses, phone numbers, department information, job titles, LinkedIn profile traces, internal references, internal documents, partner-side logs, employee identification numbers, and corporate hierarchies.
