A rootkit is a type of malicious software that is designed to hide the presence and activities of other computer software, such as malware, on a computer system. Rootkits are typically used to maintain control of an infected system, as they can be used to hide additional malicious software, add malicious user accounts, and even interfere with network communications.
Rootkits generally have the ability to conceal themselves from traditional solutions, which means they can remain undetected for quite some time. They are primarily used to gain maintenance access to a system, allowing malicious actors to access, modify, or otherwise disrupt a system without detection. Rootkits are most often installed on root level, usually with administrative privileges, giving them complete control over a system.
Rootkits can be installed manually by users with escalated privileges and there are also a variety of techniques used to spread rootkits, including viruses, worms, and Trojans. Once installed, the malicious software can be difficult to detect, as the rootkit works to hide its own processes and files from detection. Common rootkit detection methods include using intrusion detection systems (IDS) and anti-malware software.
Rootkits are destructive pieces of software that can be used to disrupt computer systems or gain access to sensitive information. As such, it is important to be aware of rootkit activity and take the necessary actions to protect against them.
