What is a rootkit designed to do?

1. Log keystrokes to capture personal information

2. Change network configurations

3. Hide itself within the OS, making detection difficult

4. Replicate itself without user intervention

The correct answer is: Hide itself within the OS, making detection difficult

A rootkit is designed to integrate deeply into the operating system to conceal its presence and maintain control over the system without detection. It typically alters system files and processes, enabling malicious software to execute or provide unauthorized access to an attacker while remaining hidden from traditional detection methods. This stealthy behavior is essential, as it allows the rootkit to persist and operate undetected, making it particularly dangerous. The focus of a rootkit on hiding itself from system monitoring and security measures is crucial, as its primary goal is to maintain control while evading detection by users and security software. Other options may describe harmful activities associated with malware, but they do not capture the primary function of a rootkit, which is concealment.
