How can malware be disguised to evade detection by antivirus software?
Malware can be disguised to evade detection by antivirus software through various techniques. These include code obfuscation, which alters the structure and appearance of the malware to make it more difficult for antivirus programs to recognize. Polymorphic malware can also change its code and behavior on each infection, making it harder for antivirus software to detect. Additionally, attackers may use packing techniques to compress and encrypt the malware, making it more challenging for antivirus scanners to identify.
To disguise malware and evade detection by antivirus software, attackers can use advanced techniques such as rootkit installation, which allows the malware to hide in the operating system and avoid detection. Another method is by utilizing zero-day vulnerabilities, which are unknown to antivirus software, to exploit systems and deliver malware. Remote Access Trojans (RATs) can also be used to gain unauthorized control over a victim's computer and bypass antivirus detection.
