Decompiled Python Code Collection by @AtomixClub
Welcome to CracksTheCodes — a curated archive of reverse-engineered Python applications, scripts, and compiled bytecode. Whether you're a security researcher, malware analyst, or just curious about how Python programs work under the hood, this repository is for you.
⚠️ Disclaimer: This repository is intended for educational and research purposes only. Please respect intellectual property and only decompile code you have permission to analyze.
AtomixClub is a reverse engineering enthusiast and Python security researcher passionate about understanding how software works at its core. This collection represents countless hours of decompilation, analysis, and documentation.
This repository contains decompiled source code from various Python formats, including:
- 📦 Compiled Python Bytecode –
.pycfiles from Python 2.7 to 3.11+ - 🔒 PyInstaller Executables – Decompiled standalone Windows/Linux/macOS apps
- 🥧 Py2EXE & Py2APP – Recovered source from packaged applications
- 📱 Python-for-Android – Kivy, BeeWare, and other mobile Python apps
- 🕸️ Obfuscated Python – Deobfuscated and cleaned source code
- 🧩 Python Modules – Extracted from various sources and platforms
The decompilation process relies on a variety of specialized Python reverse engineering tools:
| Tool | Purpose |
|---|---|
| uncompyle6 / decompyle3 | Decompile Python bytecode (Python 2.7-3.8) |
| pycdc (Python Bytecode Decompiler) | Modern decompiler supporting Python 3.9+ |
| pyinstxtractor | Extract PyInstaller packages |
| pyi-archive_viewer | Explore PyInstaller archives |
| unpy2exe | Decompile py2exe executables |
| pyREtic | Dynamic analysis for obfuscated Python |
| xdis | Cross-version Python bytecode disassembler |
| 🧠 Brain | The tool that actually does the work when all the automated ones fail |
Not all files can be perfectly restored!
Due to limitations in decompilation tools (uncompyle6, pycdc, etc.) and the nature of Python bytecode:
- 🔨 Some files decompile to 100% working source code – Clean and executable
- 🔧 Some files produce partial code – May have missing sections or syntax errors
- 📋 Some files only yield
.disoutput – Raw disassembly when decompilation fails - ❓ Some files are completely unrecoverable – Corrupted, heavily obfuscated, or unsupported Python versions
Files with .dis extension contain Python bytecode disassembly – not source code, but still useful for understanding program flow. Think of it as assembly language for Python.
- Obfuscation Techniques – Before/after comparison of obfuscated vs clean code
- Pyc Structure – Raw bytecode vs decompiled source side-by-side
- Failed Decompilations – Examples of
.disfiles and why decompilation failed
Want to try decompiling Python yourself? Here's how:
# Using uncompyle6
uncompyle6 file.pyc > file_decompiled.py
# Using pycdc (for newer Python versions)
pycdc file.pyc > file_decompiled.py# No command for this. Just pure suffering.python -m dis file.pyc > file_disassembled.dis# You're now officially a reverse engineer.
# Congratulations? 🎉# Extract the executable
python pyinstxtractor.py your_app.exe
# Decompile the extracted .pyc files
cd your_app_extracted
uncompyle6 struct.pyc > struct.py
# Question all your life choices
