What occurs when a Rootkit successfully embeds itself in an operating system?

When a Rootkit successfully embeds itself in an operating system, it primarily conceals its presence from traditional security measures. This is a key characteristic of Rootkits, as they are designed to manipulate the operating system at a low level, making them difficult to detect by standard security tools and antivirus software. By hiding their presence, Rootkits can maintain control over the compromised system, allowing malicious actions without alerting the user or security programs.

While logging keystrokes, encrypting files, and creating backdoors are actions that other types of malware may perform, these are not defining features of a Rootkit. A Rootkit's primary function is to remain hidden and facilitate further interaction with the system under the radar, which enables additional malicious activities that can proceed unchecked.
