Hnfull/Intensio-Obfuscator

Obfuscate a python code 2.x and 3.x

Intensio-Obfuscator

Project not maintained anymore

Thanks to all contributors

What is this ?

• Intensio-Obfsucator tool takes a python source code and transform it into an obfuscated python code
  • Replace all names of variables/classes/functions/files-name to random strings with length defined then all chars to their hexadecimal value
  • Delete all comments, all spaces lines
  • Padding random snippets code/functions/classes with an always differents values

What purpose ?

• Provides a high level obfuscation layer to prevent or delay the reading and understanding of your python program

Level of obfuscation

• Weak obfuscation if used alone, can be used with other types of obfuscation

Requirements

• Python >= 3.5
• requirements.txt

Files supported

• Files written in python 2.x and 3.x

Installation

• From source

$ git clone https://github.com/Hnfull/Intensio-Obfuscator.git
$ python3 -m pip install -r Intensio-Obfuscator/requirements.txt
$ cd Intensio-Obfuscator/src/intensio_obfuscator
$ python3 intensio_obfuscator.py --help

• From python package

$ python3 -m pip install intensio-obfuscator
$ intensio_obfuscator --help

Features

Features	Descriptions	Purpose of obfuscation	Compatibility with all types of python codes/syntaxes
Delete comments	Delete all comments (this feature is executed by default)	Delete potential behavioral informations	high python files 2 & 3
Delete line spaces	Delete all spaces line (this feature is executed by default)	Reduce the code visibility in clear	high python files 2 & 3
Correction padding empty classes/functions	Add padding to empty classes and functions, if the class or function contains comments only, the default feature Delete comments can potentially let a class or function empty, this will avoid to generate an error (this feature is executed by default)	None, only to avoid to generate errors	high python files 2 & 3
Replace string to string mixed	Replace all names of variables/classes/functions to random strings with length defined	Reduce the code visibility in clear - Delay the deduction of the behavior of variables/classes/functions	low - high (depends of number of names that must exclude or not) python files 2 & 3
Exclude words	file to exclude word (check documentation for the format) only for 'replace file name' obfuscation feature	Information not required	Information not required
Padding script	Add padding of random scripts after each line	Reduce the code visibility in clear - add dead snippets code/classes/functions to blur and delay behavior analysis of program	high python file 2 & 3
Replace files name	Replace all files name to random strings with length defined	Reduce the code visibility in clear - Reduce the deduction of functionnalities of files	low python files 2 & 3
Exclude file names	file to exclude file names (check documentation for the format) only for 'replace file name' obfuscation feature	Information not required	Information not required
Replace string to hex	Replace all chars to their hexadecimal value	Reduce the code visibility in clear / avoid to be detected by the 'grep' commands per example	medium python files 2 only
Correction delete pyc file	Delete all pyc file in output directory (this feature is executed by default)	Delete files already compiled without having been obfuscated before	high python files 2 & 3
Mixer length lower	Define random strings length of 32 chars when -rts, --replacetostr or -ps, --paddingscripts or -rfn, --replacefilesname or -rth, --replacetohex parameters are specified	The longer the length is used, the more difficult the visibility of the code	Information not required
Mixer length medium	Define random strings length of 64 chars when -rts, --replacetostr or -ps, --paddingscripts or -rfn, --replacefilesname or -rth, --replacetohex parameters are specified	The longer the length is used, the more difficult the visibility of the code	Information not required
Mixer length high	Define random strings length of 128 chars when -rts, --replacetostr or -ps, --paddingscripts or -rfn, --replacefilesname or -rth, --replacetohex parameters are specified	The longer the length is used, the more difficult the visibility of the code	Information not required

• Features can be executed separatly:
  • replace string to string mixed -> -rts, --replacetostr
  • padding script -> -ps, --paddingscript
  • replace file name -> -rfn, --replacefilename
  • replace string to hex -> -rth, --replacetohex
