You can always encounter numerous types of malware when browsing the internet. And some types are more harmful than others. Rootkits are part of this most harmful group of malicious software: they are very difficult to identify and remove from the system. Here, you will learn more about what they are, how they spread, how they work and, of course, how to protect yourself from them and remove them from your system.

Rootkit is a type of malicious software (or malware) widely used by malicious hackers to invade, infect and control victims' devices. Rootkits are sets of tools that allow cybercriminals to gain administrator privileges on the infected system, which allows greater freedom of action within the invaded system.
Furthermore, they offer another advantage to cybercriminals: they are extremely difficult to detect, which makes them very subtle, making it difficult to identify and adopt security measures against this type of threat, as they use very advanced techniques to avoid detection by protection mechanisms (such as antivirus software, for example). Many rootkits manage to disguise themselves as legitimate programs, which means that systems do not interpret them as a threat. They can even hide in the kernel used to control and manage the entire system, making them one of the most invasive Coinbase Virtual Currency Database groups of digital threats in action. Rootkits are also quite versatile: they can attack desktops, notebooks, laptops, mobile devices and even smart devices that are part of the IoT (Internet of Things). So, in a simple way, we can understand that rootkit is a term used to designate a group of malware created especially to guarantee access, control and dominance over infected devices, with the ability to infect not only operating systems and software in general , but the hardware itself (and also the firmware) of the infected devices. How do rootkits work? First, the rootkit needs to infect the device.
To do this, hackers use various techniques to trick victims into downloading malicious content: they disguise the rootkit as if it were a legitimate program, a trusted application or anything of the sort. Or they send emails with infected links and attachments, using phishing strategies (or any social engineering attack strategy ). When the victim clicks on one of these links or downloads any of these programs, it opens holes for the rootkit to install itself on the system. After infecting and lodging itself in the system, the rootkit begins to act without the victim noticing and without most defense mechanisms being able to detect it. At this stage, rootkits give hackers practically total control of the infected device and, in many cases, total dominance over the system. Criminals can execute files, make changes to system settings, steal sensitive personal information , monitor the victim's activities, use keylogger functions to discover passwords and credentials (such as credit card, email and social media data, for example) and a series of changes. These changes include security settings, which allow cybercriminals to spread various other types of malware and even turn the device into part of a botnet used to carry out DDoS attacks.
