What are some common techniques used by malware to evade detection by antivirus software?
Malware creators often employ various techniques to evade detection by antivirus software. Some common techniques include using packers or obfuscation tools to hide the true nature of the malware, encrypting the payload to make it harder to analyze, or using polymorphic or metamorphic code to change the structure of the malware with each new infection. Additionally, malware may use rootkit techniques to hide its presence from the operating system and antivirus software.
One way to evade detection by antivirus software is by using a specific vulnerability present in a widely used antivirus program. By exploiting this vulnerability, the malware can bypass the antivirus software without detection. Another technique is to use a Trojan horse to disguise the malware as a legitimate software update, tricking the user into installing it unknowingly.
