What are some common techniques used to hide malware from detection?
Common techniques used to hide malware from detection include code obfuscation, where the malware's source code is deliberately made difficult to understand or analyze. Another technique is polymorphism, where the malware constantly changes its code structure to evade detection by antivirus software. Rootkit installation is another method, where the malware gains elevated privileges and hides itself deep within the operating system, making it hard to detect and remove.
A sophisticated technique to hide malware from detection is known as steganography, which involves embedding the malicious code within innocent-looking images, videos, or other media files. Another method is known as process hollowing, where the malware injects its code into a legitimate process, making it appear as part of a trusted application. Finally, attackers can employ encryption to encrypt the malware's code or communications, making it difficult for security solutions to analyze and detect the malicious activity.
