How can malware creators avoid detection by antivirus software?
Malware creators employ various techniques to avoid detection by antivirus software. These techniques include code obfuscation, polymorphism, packing, and using encryption. Code obfuscation makes the malware code difficult to understand and analyze, while polymorphism allows the malware to change its code structure with each infection, making it harder to detect. Packing involves compressing the malware code and encrypting it to evade signature-based detection. Finally, using encryption techniques can hide the malware's payload, making it difficult to identify and analyze.
To avoid detection by antivirus software, malware creators can use techniques like rootkit integration, fileless malware, and zero-day exploits. Rootkit integration allows the malware to hide its presence by modifying the operating system's kernel and evading detection. Fileless malware operates in memory, leaving no traces on the infected system's hard drive, making it difficult to detect. Zero-day exploits target vulnerabilities that are unknown to antivirus software, giving the malware an advantage. These advanced techniques help malware creators stay undetected and prolong their malicious activities.
