Malicious configuration profile

Well written malware has no symptoms. My advice is to delete the profile, the apps, and restore your phone from a backup made before you downloaded the profile. That’s the only way to assure the safety of the data on your phone.

Yes, you should be very worried. When you add a configuration profile you have essentially hacked your iPhone; no legitimate app should require a profile, because any legitimate app can be made available through the app store. If an app doesn’t meet Apple’s security requirements for the app store it is most likely malware.

The only exceptions are enterprise apps created by a legitimate business for its employees, or, rarely, a beta of an app for which you are a registered beta tester. In either case the profile will be approved by Apple.
