PRIVACY: NSO Group offered ‘bags of cash’ for access to U.S. cell networks, whistleblower claims. “The mobile-phone security expert Gary Miller alleges that the offer came during a conference call in August 2017 between NSO Group officials and representatives of his employer at the time, Mobileum, a California-based company that provides security services to cellular companies worldwide. The NSO officials specifically were seeking access to what is called the SS7 network, which helps cellular companies route calls and services as their users roam the world, according to Miller.”
