Apple is suing NSO Group Technologies, the Israeli military-grade spyware manufacturer that created surveillance software used to target the mobile phones of journalists, political dissidents, and human rights activists, to block it from using Apple products.

The iPhone maker’s lawsuit, filed on Tuesday in federal court in California, alleged that NSO, the largest known Israeli cyber warfare company, had spied on and targeted Apple users. It is seeking damages as well as an order stopping NSO from using any Apple software, device, or services.

NSO develops and sells its spyware, known as Pegasus, which exploits vulnerabilities in iPhones and Android smartphones and allows those who deploy it to infiltrate a target’s device unnoticed.
