[scripts/obfuscator.py] [+] Function Name Obfuscation

Please update your code to obfuscator folder
Thanks

I am not too sure but when using the --str-gen command it is breaking my code. Is this intentional or am I using the code incorreclty?

user@user-VirtualBox:~/Desktop/PyObfx$ python3 PyObfx.py reverse.py --str-gen ch

user@user-VirtualBox:~/Desktop/obfuscators/PyObfx$ python reverse_obfx.py

File "reverse_obfx.py", line 3
SyntaxError: Non-ASCII character '\xe9' in file reverse_obfx.py on line 3, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

[scripts/tokenizer.py] Edit tokenizer for reading py file line by line.
[scripts/io.py] + File write func

@easyly471
[io.py] Check if file is a .py
[tokenizer.py] Fix tokenizer / return values properly for obfuscation

@afk
[tokenizer.py] Get values for obfuscation
[eg/stringobf.py] Write a func for string obfuscation
[obfuscate.py] Create main obfuscation class in "scripts". import stringobf.
At the end, import this class in main file and demonstrate a string obfuscation

[scripts/obfuscator.py] Create different algorithms for string encryption. Each algorithm should return a string.
[scripts/obfuscator.py] Write a func for numeric values encryption. (int, double etc.).
[scripts/packer.py] Class that responsible for encrypting and compressing file with base64, gzip etc. We don't need it now but we will later.

I ran
python3 PyObfx.py -f test/test/py
and the resulting script did not run.

I found the issue.

ZyAxHJPhav = lambda n: (n + (2 + 5)) / 1
PrKgsXMFpV = lambda s: ''.join(chr(int(ZyAxHJPhav(ord(c)))) for c in s)
...
if __name__ == PrKgsXMFpV("[[i]ej[["):
    HohxIVAa()

In this case PrKgsXMFpV("[[i]ej[[") evaluates to bbpdlqbb instead of __main__.

When I corrected this manually it appears all strings are be incorrectly represented.

Kütüphanenizi yeni gördüm, gayet güzel elinize sağlık. Bulduğum birkaç 'bug' durumunu paylaşmak istiyorum. Beta sürümü olması nedeniyle bunlar normal olabilir, ancak bunları bir geri bildirim olarak kabul edin lütfen.

Kütüphaneyi test etmek üzere indirip elimdeki şu script'i kullandım.

import socket
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

Obfuscation işlemi sonrası

# Obfuscated with PyObfx #
import socket as JSYswdTziMjk

OSsutnZLha = lambda n: (n + (2 + 2)) / 4
paOQMycZmI = lambda s: ''.join(chr(int(OSsutnZLha(ord(c)))) for c in s)
eV = JSYswdTziMjk.JSYswdTziMjk(JSYswdTziMjk.AF_INET,JSYswdTziMjk.SOCK_STREAM)

Bu durumda, socket modülünün socket fonksiyonu, obfuscation işlemine tabi tutulmaması gerekiyor.

Bir başka import etme şekli

modeule = __import__("socket")
s = module.socket(module.AF_INET,module.SOCK_STREAM)

sonuç

# Obfuscated with PyObfx #

kqpNzUDLvT = lambda n: n - sum([4, 4, 3])
SPHQDyemOf = lambda s: ''.join(chr(int(kqpNzUDLvT(ord(c)))) for c in s)
PJqBVcwOALjXyF = __import__(SPHQDyemOf("~znvp�"))
XB = module.socket(module.AF_INET,module.SOCK_STREAM)

Proje oldukça iyi, geliştikçe sorunların çözüleceğine inanıyorum. İyi çalışmalar 👍

Describe the bug
PyObfx obfuscates the Python builtin "exec" as a random variable name but fails to set it. For example, exec(myfunction) is replaced by aashcdhs(acdbchdc) with no definition of aashcdhs.

To Reproduce
Steps to reproduce the behavior:

1. Create a sample script that uses exec (I am making a remote code execution malware program for fun)
2. Run PyObfx on the script
3. Execute and see the error

Expected behavior
There should be a definition that maps the random name to the exec statement

Screenshots
None

Desktop (please complete the following information):

• OS: Windows 10
• Browser Chrome
• Version Latest version of PyObfx (git cloned it yesterday)

Obfuscator obfuscates magic methods too. It's a big problem for class based programs, obfuscator should ignore them.

[scripts/obfuscator.py] [+] Variable Value Obfuscation

[scripts/strgen.py] Write a function for random string generation.
Params will be the string type (unicode)[boolean], language[chinese/japanese for instance] and string length.
At the end, import this class and demonstrate a random generation with random length.

Describe the bug

Obfuscation of import <library-name> as <short-name> produces unusable results.

To Reproduce
Steps to reproduce the behavior:

1. create a filen called test.py with content

import pandas as pd 

df = pd.DataFrame()

print(type(df))

2. run > python test.py. It will print to stdout: <class 'pandas.core.frame.DataFrame'>

3. Obfuscate with > python PyObfx.py -f test.py

4. the resulting test_obfx.py looks like:

# Obfuscated with PyObfx #
import pandas OnUVvJaBoxpz

TROhSgWpkL = lambda n: n - sum([5, 4, 1])
vVtdzETYyL = lambda s: ''.join(chr(int(TROhSgWpkL(ord(c)))) for c in s)
rXkhlFus = pd.DataFrame()

print(type(rXkhlFus))

4. run > python test_obfx.py. The error you get is:

File "test_obfx.py", line 2
    import pandas OnUVvJaBoxpz
                             ^
SyntaxError: invalid syntax

Expected behavior
It should be on the lines of;

# Obfuscated with PyObfx #
import pandas as OnUVvJaBoxpz

TROhSgWpkL = lambda n: n - sum([5, 4, 1])
vVtdzETYyL = lambda s: ''.join(chr(int(TROhSgWpkL(ord(c)))) for c in s)
rXkhlFus = OnUVvJaBoxpz.DataFrame()

print(type(rXkhlFus))

Additional context

import pandas as pd or import numpy as np are a common convention used widely in python programming for data science/machine learning.
