How can malware evade detection by antivirus software?
Malware can evade detection by antivirus software through various techniques, such as obfuscating its code, using polymorphic or metamorphic techniques to modify its signature, employing rootkit technologies to hide its presence, and utilizing packers or crypters to encrypt the malicious payload. Additionally, malware authors may constantly update their code to stay ahead of antivirus signatures and use sandbox evasion techniques to avoid execution in controlled environments.
One effective way for malware to evade detection by antivirus software is by exploiting vulnerabilities in the antivirus software itself. By exploiting these vulnerabilities, the malware can disable or bypass the antivirus software, allowing it to operate undetected on the system. Another method is to encrypt the malware code using custom encryption algorithms that are not recognized by antivirus signatures, making it difficult for the antivirus software to identify and detect the malicious code.
