NXcrypt - 'python backdoor' framework

nxcrypt's Issues

not an issue just a question.

don't you think it's a bit ironic that the script you use to crypt your python "backdoor" is written in python, :P

pyinstaller doesnt conert the .py to .exe

cant convert the py file to exe.....any method working?

works in runtime?

It's only not detected in scan time? or run?

encoding problems

Good job for your script, but I encountered an issue. After crypting, and when I open the crypted program, it raises: File "myscript.py", line 1 SyntaxError: Non-UTF-8 code starting with '\xf3' in file myscript.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

but it raises an invalid syntax. Where am I wrong?

have an error

hello,

i'm trying this tool but i have this problem :
Sorry: TypeError: compile() expected string without null bytes

someone already have this ?

thanks

Error when I try to compile it to .exe

Hello,
My Question is very simple, I try many times to convert a output file to .exe with pyinstaller or py2exe but... I have some errors : File "/usr/local/lib/python3.8/dist-packages/PyInstaller/building/build_main.py", line 413, in assemble
priority_scripts.append(self.graph.run_script(script))
File "/usr/local/lib/python3.8/dist-packages/PyInstaller/depend/analysis.py", line 301, in run_script
self._top_script_node = super(PyiModuleGraph, self).run_script(
File "/usr/local/lib/python3.8/dist-packages/PyInstaller/lib/modulegraph/modulegraph.py", line 1390, in run_script
contents = fp.read() + '\n'
File "/usr/lib/python3.8/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf3 in position 1: invalid continuation byte

I think the junkcode injected by the NXCrypt cause some issues.
The other solution I have see is to use an older version of Python but I need ur help and ur opinion about that

[Question] Compile output

Is it possible to compile the py output to exe ?

can't work

thank u for your excellent job!

details

Invalid Syntax Errors

Hey,

For some odd reason, when I attempt to encode a simple payload from msfvenom thats encoded in base64, your program gives me an invalid syntax error.

HERE IS WHAT I TYPED AND THE CONSOLE LOG:

root@kali:~/NXcrypt# python NXcrypt.py -f /root/Desktop/hack.py -o /root/Desktop/meme.py

Compiling to exe

Can I use Pyarmor for compiling it into exe file?

Dear Sir

Please don't upload to fuck'en virustotal thanks:)

Commands module not found

Not opening meterpreter session!

After converting the payload to FUD using NXcrypt, the payload no longer open a meterpreter sessions!

This requires 'root'... why exactly?

So, Hadi, why exactly does this script of yours require root permissions to run? I skimmed through it and see no function that would require higher privileges than a simple user.

Care to comment on this?
