Do not install IPAs from untrusted sources.
Keep iOS and apps up to date from the official App Store.

If you suspect compromise, change passwords on another trusted device, remove the device from Apple ID, and consider a factory reset.
For organizations: restrict mobile device management (MDM) to prevent sideloaded apps and block enterprise profile installation.
