What is a Rootkit?


A rootkit is a type of malware that allows attackers to gain access to and control a victim's system undetected. They usually work by hooking into the victim's operating system kernel and hiding from view. Once installed, a rootkit can be used to steal sensitive information, launch attacks on other systems, or even take complete control of the victim's system.

Rootkits are notoriously tricky to detect and remove, making them a serious threat to individuals and organizations. If you think your system is infected and wondering how to detect it, you must run a scan with an antivirus program that includes rootkit detection capabilities.

What is a rootkit?

Rootkits operate by altering user account permissions and security through a process called 'modification.' A computer administrator typically authorizes this process. The purpose of modification in computers is to make valuable modifications to improve systems. However, attackers seeking complete control might use modification to gain unfettered access. In addition, since rootkits are not designed to spread on their own, attackers typically use covert methods to distribute them.

The attacker can also install a rootkit if they have root or administrator access. Attackers can gain access using known vulnerabilities, like privilege escalation or phishing for personal passwords. This process is sometimes automated.

How to detect a rootkit?

There are several ways to check for a rootkit in a system. One is to scan the system with an anti-malware program — many of these can detect and remove rootkits.

Another option is to use a dedicated rootkit detection tool. These tools are designed specifically to look for signs of a rootkit and can be very effective at finding them.

Finally, you can also check for signs of a rootkit manually. This process is tricky as rootkits are designed to be stealthy and difficult to spot. However, there are some common indicators that you can look for:

  • Unusual or unexplained activity on your computer.

  • Files or programs that suddenly appear or disappear.

  • Changes to system settings that you didn't make.

  • Slow performance or strange errors.

If you notice any of these things, you may be dealing with a rootkit. Of course, not all these signs necessarily mean that you have a rootkit — there may be other problems as well. However, if you see multiple suspicious symptoms, it's worth an investigation.

How to remove a rootkit?

When downloading software or surfing the internet, exercise caution since rootkits are dangerous and difficult to detect. You may employ the same safeguards you use to avoid computer viruses to reduce the risk of rootkits:

1. Implement an all-encompassing cyber security solution

Install a robust and comprehensive antivirus solution on your devices. Consider selecting a security program that protects you from cyberattacks and scans your computer for rootkits.

2. Stay up to date

Keeping your software up to date is critical for staying safe and preventing malware infection. Updating your operating system and programs will help you avoid rootkit attacks.

3. Keep an eye out for phishing scams

Phishing is a type of social engineering assault in which scammers use email to mislead consumers into disclosing financial information or downloading harmful software such as rootkits. To prevent rootkits from infecting your machine, avoid opening suspicious emails, especially if the sender is unknown to you. If you are unsure whether a link is reliable, do not click on it.

4. Use only reputable sites to download files

To avoid rootkit installation, be cautious while opening attachments; avoid opening attachments from individuals you don't know. Download software only from reliable websites. When your web browser warns you that a website you're trying to access is hazardous, don't disregard it.


Malware such as rootkits gives attackers complete control over your system. Preventive measures are essential against rootkits because they are tough to detect and remove. Running a reputable anti-malware program and keeping your software up to date are the best ways to avoid rootkits. Be extra careful while downloading files and opening attachments from unknown individuals.
