Summary of the Article: Rootkits and Their Impact
1. Rootkit Introduction:
A rootkit is a software tool that grants unauthorized access to a computer or network, enabling an attacker to control various aspects of the operating system. Originally, rootkits were developed to provide administrator-level access to Unix and Linux systems.
2. Common Ways to Get a Rootkit:
The most common method for someone to get a rootkit on their computer is through phishing or social engineering attacks. Victims unknowingly download and install malware embedded within other processes on their machines, giving hackers control over the operating system.
3. Origin of the Term “Rootkit”:
The term “rootkit” is a combination of “root” and “kit.” “Root” refers to the admin account on Unix and Linux systems, while “kit” refers to the software components that implement the tool.
4. Installation Locations of Rootkits:
Rootkits typically operate near or within the kernel of the operating system, granting them low-level access to execute commands on the computer. Nowadays, rootkits have evolved to target Internet of Things (IoT) devices, turning them into zombie computers for malicious activities.
5. Removal of Rootkits:
You can remove rootkits from your computer using various tools such as Avast Rootkit Scanner, Malwarebytes, Kaspersky, Lynis, or McAfee. These rootkit removal software perform thorough scans to eliminate any malicious software, ensuring your computer is free from infections.
6. Difficulty in Detecting Rootkits:
Detecting rootkits can be challenging as they can range from low-level firmware attacks to high-privileged operations. Moreover, rootkits have the ability to disable security software, making it harder to track and identify any keylogging or other malicious activities.
7. Frequency of Rootkit Attacks:
Compared to other types of malware, rootkits are less common in the attacker’s arsenal. According to Bitdefender, less than 1% of the total detected malware is classified as rootkits. However, it is important to note that all instances of detection are associated with high-profile attacks.
8. Spread of Rootkits:
In order to spread a rootkit, attackers create a blended threat by exploiting multiple vulnerabilities. This involves combining the rootkit with a dropper and a loader, allowing the rootkit to infiltrate and compromise the targeted system.
Questions and Answers:
1. How can someone get a rootkit on their computer?
A rootkit is typically acquired through phishing or social engineering attacks where users unknowingly download and install malware.
2. What is the origin of the term “rootkit”?
The term “rootkit” is derived from the words “root” (referring to the admin account on Unix and Linux systems) and “kit” (representing the software components of the tool).
3. Where are rootkits usually installed?
Rootkits operate near or within the kernel of the operating system, granting them deep access to execute commands on the computer.
4. How can rootkits be removed from a computer?
Rootkit removal tools such as Avast Rootkit Scanner, Malwarebytes, Kaspersky, Lynis, or McAfee can be used to scan and eliminate rootkits from an infected machine.
5. Is detecting a rootkit difficult?
Rootkits can be challenging to detect due to their ability to disable security software and perform covert malicious activities like keylogging.
6. How common are rootkit attacks?
Rootkit attacks account for less than 1% of the total detected malware. However, they are associated with high-profile attacks.

Where does rootkit come from
The term rootkit is a connection of the two words "root" and "kit." Originally, a rootkit was a collection of tools that enabled administrator-level access to a computer or network. Root refers to the Admin account on Unix and Linux systems, and kit refers to the software components that implement the tool.

Is it hard to detect a rootkit
Rootkits can range from low level firmware attacks through high privileged operations. Rootkits also give hackers the ability to disable security software to track the keys that are tapped on your computer. Because rootkits hijack security software, they are hard to detect.
How common are rootkit attacks
Compared to other tools in the attacker's arsenal, rootkits are less common than other types of malware. For example, according to Bitdefender, rootkits account for less than 1% of the total malware detected. That said, all instances of detection are associated with high-profile attacks.
How does a rootkit spread
Blended threat
A rootkit cannot infect target computers on its own. In order to spread a rootkit, attackers form a blended threat to exploit several different vulnerabilities and infiltrate a system. This is achieved by combining the rootkit with two other components—a dropper, and a loader.
