Python / Nuitka / PyInstaller

Protect your Python applications compiled with Nuitka or PyInstaller

Compile your Python code to a native binary with Nuitka, then apply real binary protection. Code virtualization, string encryption, and anti-analysis defenses.

The Problem

Current Python protection tools are broken

PyArmor is cracked

PyArmor's obfuscation has been publicly defeated. Multiple tools exist to deobfuscate PyArmor-protected scripts. Paying for PyArmor gives you a false sense of security.

PyInstaller is trivially extracted

PyInstaller bundles .pyc files in a ZIP archive. Tools like pyinstxtractor and uncompyle6 extract and decompile the original source code in seconds. It is not protection.

Nuitka output is still readable

Nuitka compiles Python to C, then to native code. This is better than .pyc, but the resulting binary is standard C code. IDA Pro and Ghidra decompile it back to readable logic.

The Solution

Compile to native, then protect the binary

The right approach is a two-step pipeline. First, compile your Python application to a native executable using Nuitka. This eliminates .pyc files and bytecode extraction entirely. Then, run ChaosProtector on the compiled binary. Your functions are virtualized into encrypted bytecode. Strings are encrypted. Import tables are wiped. Debuggers are blocked. The result is a Python application that is genuinely hard to reverse engineer.

How It Works

Compile, protect, ship.

Compile with Nuitka

Use Nuitka --standalone or --onefile to compile your Python application to a native Windows executable. This is the input.

Run ChaosProtector

Open the GUI or use the CLI. Load the compiled .exe, select functions to protect, and choose your protection level.

Ship the protected binary

The output is a hardened Windows PE. Same functionality. Now resistant to reverse engineering, debugging, and tampering.

Features

Full protection stack for Python executables

🔒

Code Virtualization

The native x86-64 instructions generated by Nuitka are replaced with encrypted custom bytecode. Your Python logic, now compiled to machine code, becomes an unknown instruction set.

🔐

String Encryption

All string literals are encrypted at rest and decrypted only at runtime. API keys, database URLs, and internal messages vanish from the binary.

🛡

Anti-Debug

TLS callback detection blocks debuggers before your application starts. Works against x64dbg, WinDbg, and all common Windows debuggers.

💥

Anti-Disassembly

Exploits CVE-2024-44083 to crash IDA Pro during loading. Static analysis is blocked before it begins. Covers IDA versions up to 8.4.

✅

Integrity Check

CRC32 verification of the .text section at runtime. Any patch or modification terminates the process immediately. Stops crackers from NOPing out your license checks.

📦

Import Protection

Windows API calls are resolved at runtime via PEB walking. Import tables are wiped clean. API monitoring tools cannot trace your calls.

🧹

Zero AV False Positives

ChaosProtector does not use packing, process hollowing, or other techniques that trigger antivirus heuristics. Protected binaries pass VirusTotal cleanly.
