What are some common techniques used by malware to evade detection by antivirus software?
Malware creators often use obfuscation techniques to hide their malicious code from antivirus software. This can include encrypting the code, using packers or compressors, and employing polymorphic or metamorphic techniques to constantly change the code's appearance. They may also utilize rootkit technologies to hide the presence of the malware on the infected system.
One effective technique used by malware to evade detection is to exploit zero-day vulnerabilities in antivirus software. By identifying and exploiting these vulnerabilities, the malware can bypass the antivirus software's detection mechanisms. Additionally, some malware creators collaborate with insiders in antivirus companies to obtain information about the software's detection methods and update their malware accordingly.
