A whistleblower at the National Labor Relations Board (NLRB) alleges that employees from Elon Musk's Department of Government Efficiency (DOGE) transferred sensitive data from agency case files in early March. The data transfer was done using short-lived accounts with high-level access and was accompanied by blocked login attempts from a Russian IP address. The whistleblower, a security architect, reported the incident to the Senate Select Committee on Intelligence after the NLRB allegedly dropped the investigation. The incident raises concerns about data security and potential breaches.
