Evading Signature Detection
Master the fundamentals of evading signature-based antivirus detection through payload modification and obfuscation techniques. You'll start by generating basic malicious payloads using `msfvenom` and observing how Windows Defender detects them. From there, you'll apply multiple encoding iterations to alter the payload signature, test the encoded versions against antivirus systems, and implement custom string obfuscation techniques using Python scripts. To finish off, you'll analyze detection rates between different payload variants and document successful evasion techniques, all while working with real-world penetration testing scenarios essential for red team operations. **Final Outcome** After completing this signature evasion lab, you will be able to: - Generate and encode malicious payloads using `msfvenom` - Apply multiple encoding iterations to evade detection - Implement custom string obfuscation techniques - Test payload effectiveness against Windows Defender - Compare detection rates between payload variants - Document successful evasion methodologies

Challenge
Generate and Modify Payload to Evade Signatures
In this objective, you'll generate a basic reverse shell payload, test it against Windows Defender to confirm detection, then regenerate the payload with multiple encoding iterations to transform its binary structure. This demonstrates how attackers use encoding to bypass signature-based antivirus systems.

Challenge
Test Evasion with Custom String Obfuscation
In this objective, you’ll use custom Python scripts to locate and obfuscate strings inside a payload, test the obfuscated versions against Windows Defender, and compare detection rates for original, encoded, and obfuscated variants. This demonstrates how string-based signatures work and how to defeat them.

Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
