How can malware be disguised to evade detection by antivirus software?
Malware can be disguised to evade detection by antivirus software using various techniques such as code obfuscation, polymorphism, and encryption. Code obfuscation involves modifying the malware's code to make it more difficult for antivirus programs to recognize and analyze it. Polymorphism allows the malware to change its code structure and appearance each time it infects a new system, making it harder for antivirus software to detect. Encryption involves encrypting the malware's code or payload, making it unreadable to antivirus programs until it is decrypted.
To disguise malware and evade detection by antivirus software, you can use packers and crypters that will compress and encrypt the malware's code, making it undetectable to most antivirus programs. Additionally, you can use rootkit techniques to hide the malware from the operating system and any security software running on the infected system. By modifying the malware's code signatures and behavior, you can also bypass antivirus heuristics and signature-based detection methods.
