Evolution and Detection of Polymorphic and Metamorphic Malwares: A Survey

TL;DR

This survey reviews the evolution of polymorphic and metamorphic malwares and discusses the challenges they pose to traditional detection methods, highlighting recent advancements in malware detection techniques.

Contribution

It provides a comprehensive overview of malware evolution and evaluates current detection techniques addressing polymorphic and metamorphic malware complexities.

Findings

Malware complexity has increased with polymorphic and metamorphic variants.

Traditional anti-malware methods struggle with evolving malware structures.

Recent detection techniques aim to reduce false alarms while identifying complex malware.

Abstract

Malwares are big threat to digital world and evolving with high complexity. It can penetrate networks, steal confidential information from computers, bring down servers and can cripple infrastructures etc. To combat the threat/attacks from the malwares, anti- malwares have been developed. The existing anti-malwares are mostly based on the assumption that the malware structure does not changes appreciably. But the recent advancement in second generation malwares can create variants and hence posed a challenge to anti-malwares developers. To combat the threat/attacks from the second generation malwares with low false alarm we present our survey on malwares and its detection techniques.
