WhatsApp has filed a suit in federal court accusing Israeli mobile surveillance maker NSO Group of creating an exploit that was used hundreds of times to hack into target’s phone.

The lawsuit, filed in a California federal court, said the mobile surveillance outfit “developed their malware in order to access messages and other communications after they were decrypted” on target devices.
