Fully Undetectable (FUD) Crypter’s, pivotal for eluding antivirus detection, necessitate advanced techniques. This study explores encryption, code obfuscation and anti-virus evasion techniques implemented in FUD Crypter development. It plays a crucial role by bypassing vigilant antivirus software. As the arms race between malware creators and security defenders intensifies, the development of FUD Crypter’s demands the integration of advanced techniques. This study rigorously examines the efficacy of our FUD Crypter’s design and different mechanism engaged in the process, subjecting them to comprehensive evaluations against a spectrum of antivirus solutions. Additionally, the research delves into the intricacies of conversion processes, limitations, and the normalization characteristics of some well-known malwares. It further scrutinizes the attributes of Python-based malware through the lens of normalization curves, encompassing both size and execution time metrics. Empirical analyses contain extensive Python malware datasets and evaluations across prominent platforms. The culmination of these insights underscores the development of a robust and holistic antivirus evasion strategy.
