The “prepend” option in this script can be used to overcome this. Usually, this is because it’s missing the magic bytes for the Python version number within the Python bytecodes.

Occasionally, the main Python file, which contains the main logic for the program, can’t be decompiled.

Once everything is unpacked, it will proceed with decompiling all the extracted Python byte code by using uncompyle6.

However, if the script detected any encrypted bytecode, it will ask whether it should proceed with the decryption process (Figure 7).

After it has completed the check it will proceed using either unpy2exe.py or pyinstxtractor.py for unpacking.

Once a binary is specified as input, it will automatically determine if this is packed using py2exe or PyInstaller.

This will bundle everything into one executable.Ĭ:\Users\test\Desktop\test>pyinstaller -onefile hello.pyĥ967 INFO: Building EXE because out00-EXE.toc is non existentĥ982 INFO: Building EXE from out00-EXE.tocĥ982 INFO: Appending archive to EXE C:\Users\test\Desktop\test\dist\hello.exeĦ325 INFO: Building EXE from out00-EXE.toc completed successfully.Ī number of useful Python decompilation scripts already exist, including unpy2exe.py, pyinstxtractor.py and uncompyle6 however, each supports different options and file types. To speed up analysis the Countercept team created a single script ( Github) that can be used as a one stop shop for decompilation, calling other scripts as needed. After that, we will issue the command “pyinstaller –onefile hello.py” (a reminder that ‘hello.py’ is our payload).

Install PyInstaller using pip (pip install pyinstaller).

Once the script is ready, we will issue the command “python setup.py py2exe”.

The option “bundle_files” with the value of 1 will bundle everything including Python interpreter into one exe.

For the payload (in this case, we will name it hello.py), use a script like the one in Figure 1.

To start off we’re going to show you how payloads can be compiled in py2exe and PyInstaller.

In this article we’ll walk through how to generate Python binaries and how our script can be used to decompile them.
