Python Obfuscation and Analysis Evasion Techniques

Why this course?

Sometimes you need your code to be hard to read. Post-delivery control, license management, intellectual property protection… There are legitimate reasons to hide logic.

This course teaches you how to create, execute and hide Python code you need to keep under the radar. It’s not theory: you’ll implement real techniques that work against static analysis tools.

Dani García has created hacking tools that are still in use. He knows the techniques from both sides: hiding and analyzing. Here he shares that knowledge.

By the end, you’ll create a functional obfuscated TCP payload in one line that evades most automatic detection tools.

What you’ll learn

• Dynamic code execution: eval(), exec(), compile() and more
• Hiding techniques: How to hide dangerous method calls
• Static vs dynamic analysis: What tools detect and how to avoid it
• Bytecode and marshal: Code compilation and serialization
• Manual obfuscation: Artisanal techniques that work
• Obfuscation tools: Process automation
• Encoding: Base64, ROT13 and combined techniques
• Tool evasion: Bandit, Semgrep, Pysa and others

Final Project

Obfuscated TCP payload in one line:

• Connects to remote server via TCP
• Sends information without raising suspicion
• Obfuscated with multiple techniques
• Evades static analysis

Who is this for?

• Advanced Python developers who need to protect their code
• Security researchers who analyze malware
• Red teamers who need evasion techniques
• CTF enthusiasts in reversing challenges
• Product developers who want to protect licenses

Prerequisites

• Intermediate-advanced Python level (required)
• Mastery of functions, imports and string handling
• Familiarity with security concepts (recommended)
