Detailed explanation-1: -Rootkits are a type of malware that are designed so that they can remain hidden on your computer. But while you might not notice them, they are active. Rootkits give cybercriminals the ability to remotely control your computer.
Detailed explanation-2: -Rootkit malware is a collection of software designed to give malicious actors control of a computer network or application. Once activated, the malicious program sets up a backdoor exploit and may deliver additional malware, such as ransomware, bots, keyloggers or trojans.
Detailed explanation-3: -Some examples include: User-mode or application rootkit – These are installed in a shared library and operate at the application layer, where they can modify application and API behavior. User-mode rootkits are relatively easy to detect because they operate at the same layer as anti-virus programs.
Detailed explanation-4: -Rootkits hide by using some of the lower layers of the operating system, including API function redirection or undocumented OS functions, which makes them almost undetectable by common anti-malware software.
Detailed explanation-5: -It is common that a rootkit creates a hidden, encrypted filesystem in which it can hide other malware or original copies of files it has infected. Operating systems are evolving to counter the threat of kernel-mode rootkits.
