BrowserBackdoor

BrowserBackdoor is an Electron application that uses a JavaScript WebSocket Backdoor to connect to the listener.

BrowserBackdoorServer is a WebSocket server that listens for incoming WebSocket connections and creates a command-line interface for sending commands to the remote system.

The JavaScript backdoor in BrowserBackdoor can be used on all browsers that support WebSockets. It will not have access to the Electron API of the host computer unless the BrowserBackdoor Client application is used.

Some things you can do if you have access to the Electron API:

[Open new browser windows that can point to any website.] (http://electron.atom.io/docs/api/browser-window/#new-browserwindowoptions)
[Change and read the clipboard.] (http://electron.atom.io/docs/api/clipboard/#clipboard) (already built-in. See: server/modules/readClipboard.js and server/modules/writeClipboard.js).
[Access cross-platform Operating System notifications and the tray on OS X and Windows.] (http://electron.atom.io/docs/api/tray/#tray)
[Take screenshots.] (http://electron.atom.io/docs/api/desktop-capturer/#desktopcapturer) (already built-in. See: server/modules/screenshot.js).
[Execute arbitrary system commands.] (http://stackoverflow.com/a/28394895) (already built-in. See: server/modules/execCommand.js)
Run at startup. (already built-in. See: client/main.js and server/modules/enableStartup.js).
