Eleanor


Eleanor comes as a drag-and-drop file utility called EasyDoc Converter. This application bundle wraps a shell script that uses Dropbox name as a disguise and installs three components: a hidden Tor service, a Pastebin agent and a web service with a PHP-based graphical interface.

The Tor service transforms the victim’s computer into a server that provides attackers with full anonymous access to the infected machine via Tor-generated address.

The Pastebin agent uploads the address in encrypted form to the Pastebin website where the attackers can obtain it.

The web service is the main malicious component that provides the attackers with the control over the infected machine. After successful authentication, the interface offers several control panels to the attackers, allowing them to do the following actions:

- Managing files
- Listing processes
- Connecting to various database management systems such as MySQL or SQLite
- Connecting via bind/reverse shell
- Executing shell command
- Capturing and browsing images and videos from the victim’s webcam
- Sending emails with an attachment
