: Often used in the context of "modded" or "stealth" apps that are intended to run without a visible icon or notification.

: If you accidentally ran a file like this, go to Settings > General > VPN & Device Management on your iPhone. If you see any unknown "Configuration Profiles," delete them immediately, as they can be used to hijack your web traffic or install unauthorized apps.
