Malware Obfuscation Techniques: A Brief Survey

Key Points

• Analyze how malware creators apply code obfuscation techniques to evade standard antivirus detection mechanisms.
• Reviewed evasion architectures across four primary obfuscation categories: encrypted, oligomorphic, polymorphic, and metamorphic malware.
• Assessed emerging patterns and future technical directions in malware obfuscation strategies.
• Demonstrated how structural transformations and encryption routines enable malicious binaries to evade signature-based detection engines.
• Outlined evolutionary trends in obfuscation engineering that necessitate more adaptive, heuristic-driven security frameworks.
