Cracking And Analyzing Apple iCloud Protocols: iCloud Backups, Find My iPhone, Document Storage.

Apple iCloud was meant to improve flexibility and comfort when using your iDevices, however it also provides opportunities to extract as much as everything about the user.

Backups: iCloud suggests backing up iMessage, SMS, photos and videos, device settings, documents, music and other things on-the-fly, which is useful for syncing or restoring in case your iDevice is lost or damaged. However, there is only one way to access iCloud backup data by organic means: You can only restore the backup onto any of your devices (linked to the same account) and, thus, only via Wi-Fi connection. This technical limitation is presupposed by design. But now I can show you a method to simply download everything onto any desired computer at hand, provided that we have Apple ID and password.

Find My iPhone: this application was meant to help you to track your own iDevices geographically and should be available strictly to the user under his/her own Apple account. But there is a way to get the geo-location data having neither a Apple device tethered to that account readily available nor access to the iCloud website. If the location services are switched on, the geo-location of the device can be detected by sending a push request (there will be an arrow indicator in the right upper corner of the target device screen) and getting the requested coordinates. Then, the received positioning data can be applied to any map you prefer (incl. Google Maps or any other map).

Storage: Apart from backup iCloud can store iTunes contents, photo stream, contacts, iWork documents, application files and more, which can be accessed either from any device signed up to the account or from However, not all information can be accessed from iCloud webpage. For example, some application files (e.g. data generated by SoundHound) you may have on your iPad – or whatever – won’t be seen from Our technological analysis allowed us to make it possible to access and download all storage information, including third-party application files on-the-fly, even without launching a work session in iCloud.

Conclusion: iCloud stores large amounts of information. Before now access to this info was restricted either by the necessity to have iDevice available or by using Internet and web-browser (knowing Apple ID and password is required). Now, that I have reverse-engineered Apple iCloud communication protocols we can suggest an alternative technology to reach and download iCloud data and its changes in standalone mode.
