There are three major mobile operating systems, and three major cloud services. Most Android users are deep into the Google’s ecosystem. iCloud is an essential part of iOS, while cloud services provided by Microsoft under the OneDrive umbrella are used not only by the few Windows Phone and Windows 10 Mobile customers but by users of other mobile and desktop platforms.

In this article, we’ll try to figure out what types of data are available for extraction and forensic analysis in the three major cloud platforms: Apple iCloud, Google Account and Microsoft Account.

Acquisition Tools

For the purpose of this article, we will use ElcomSoft-developed cloud extraction tools.
