# NXcrypt

- NXcrypt is a polymorphic 'python backdoors' crypter written in python by Hadi Mene (h4d3s) .

The output  is fully undetectable .

- NXcrypt can inject malicious python file into  a normal file with multi-threading system .

- Run it with superuser's permissions .

- NXcrypt output is Fully undetectable  .

Encryption Module

# Usage :

- sudo  ./NXcrypt.py --file=backdoor.py --output=output_backdoor.py # encrypt backdoor.py and output file is output_backdoor.py

- sudo ./NXcrypt.py --file=shell.py # encrypt shell.py and default output file  is backdoor.py but you can edit it in source code

 - sudo ./NXcrypt.py --help # NXcrypt help

 - sudo ./NXcrypt.py --backdoor-file=payload.py --file=test.py --output=hacked.py # inject payload.py with  test.py into hacked.py with multi-threading system

 

 # How it work ? 

 

 * Encryption module :

 

 - NXcrypt add some junkcode .

 - NXcrypt use a python internal module 'py_compile' who compile the code into bytecode to a .pyc file .

 - NXcrypt convert .pyc file into normal .py file .

 - And in this way we can obfuscate the code

 - The md5sum will change too

 

* Injection  module :

- it inject a malicious python file  into a normal file with multi-threading system .
