Wednesday, August 3rd, 2016

Just now, we’ve updated Elcomsoft Cloud Explorer to version 1.10. This new release adds the ability to download email messages from the user’s Gmail account for offline analysis. In order to do that, we had to develop a highly specialized email client. We opted to use Google’s proprietary Gmail API to download mail. In this article, we’ll explain our decision and detail the benefits you’ll be getting by choosing a tool that can talk to Gmail in Gmail language.

Elcomsoft Cloud Explorer does exactly that: it offers read-only mail extraction to create an offline backup of messages from the user’s online account.
