How to Prevent App Signing by Unauthorized Developers

Fraudsters and other cyber-criminals routinely copy, clone, or embed malware inside legitimate mobile apps. After that, they repackage, re-sign and re-distribute these fake/malicious apps on a wide variety of app stores and for lots of different reasons, sometimes even masquerading as the original owner/developer of the app.

Learn the 3 easy steps to prevent iOS apps against mobile piracy by validating that the app has been signed by authorized developers only.

Why Should Developers protect iOS apps with Secure App Signature Validation?

Any app that was copied using a jailbroken phone, either distributed from the app store or by any other method, can be modified, re-signed and re-distributed to the App Store, to an alternative app store, or sent to another individual for malicious use.
