Misuse of enterprise and developer certificates

There is some distribution of apps outside the App Store using provisioning profiles and enterprise certificates, which allows those apps to be installed on non-jailbroken iOS devices. This violates Apple's developer agreements.

Some of them use a provisioning profile that requires the user to set the device's time back to 2012 before installing the app.

Examples

 * nds4ios - an emulator app.
 * Some piracy sites and tools distribute cracked App Store apps that have been re-signed using developer certificates.
 * iOSEmulatorSpot, JBWithoutJB, and NoJailbreakApps redistribute various apps developed by other people, mostly without permission.
 * Pangu
