You’ll need to connect your iPhone to your computer to check for Pegasus spyware.

In the ongoing battle between Apple and the Pegasus spyware, the iPhone maker today said it was suing the NSO Group — the maker of surveillance software. Apple said it is seeking to protect its users from “further abuse and harm” with a permanent injunction to ban NSO Group from using the iPhone maker’s hardware, software or devices, Apple said in a release.

The spyware can be remotely installed on a target’s iPhone or iPad, granting the person or organization who installed it full access to the device and all the data it holds — without the owner taking any action. That includes text messages, emails and even recording phone calls. Pegasus was originally designed and is marketed by its creator the NSO Group to monitor criminals and terrorists.
