One of the problems that most affects computers is viruses and malware, because they can be found practically anywhere, be it in a website, in a file that is downloaded over the Internet or through an email received. The truth is that any of them can reach considerably affect the performance of your machine.
In general, when the computer has been infected, over time it begins to show some symptoms of them, as it is a much slower operation, problems in executing some tasks, slowness in booting at startup, among others. In the event that you are affected by a rootkits You probably won’t even notice it, since one of its functions is to make believe the user that everything is fine while carrying out each of their illegal activities.
Being a malware that works invisibly It is very important to be able to know everything related to him, what is it, how does it work, how many types exist and above all how to know if your computer is being affected by rootkits. So that you can begin to know all these details, simply follow in detail everything that we will teach you next in the post.
What are rootkits and what are these types of software for?
They are considered one of the most dangerous malware that allows specific people to carry out Criminal acts at the time of access your computer without your prior authorization.
the same usually access computers silently and likewise stay hidden in them while carrying out each their illegal activities. These types of malware They are mainly used to manipulate computer equipment without the owners’ authorization and above all without their being aware of it. One of his main tasks is to hide processes and files that allows the intruder to be constantly accessing the computer.
Furthermore, it should be mentioned that these malicious software are used in a wide variety of operating systems. Finally you can define what the word is root kitsin the case of root it meansthat is, that there will be access to all device details and aspectswhile Kit means the way unlock access to affected computer.
Functions of a Rootkit What can they do and what are they used for?
The main function of rootkits is to make another malware can successfully hide within the destination computerhe himself will be in charge of making cleaning processes inside the machine cannot be executed correctly, avoiding being removed from there.
When these items have been installed on the computer, automatically get a remote access to all functions of operating system in a secret way. To hide your tracks on the computer they work from system programming depths. This will prevent them from being easily detected, all of these preventive measures they take are what make it so dangerous.
Many of them have the ability to reach disable or manipulate security programs installed on the computerso these will not be able to detect them, much less eliminate them. It is important to mention that these elements are used mostly by people to achieve extract personal data and other private information of other equipment to later use them to carry out malicious activity or financial fraud.
Companies are constantly affected by these types of software. Finally, it should be mentioned that the creators of rootkits they have the ability to tailor it to their needs, so many of them leave a back door to access the system whenever they want, while others they prefer to spy on the user all the timethus achieving extract all data and content that is of value to them to carry out each of its activities.
Types of Rootkits What are all that exist and what does each one do?
It is important to mention that rootkits are generally divided into six categorieseach of these types are based primarily on the part where affect the infected computer and its level. Considering that this is a very dangerous malware, It is very important to be able to know it in detail and know which of them exists.
In this way, here we show you each of the types of rootkits that currently exist:
user mode
rootkits of these types tend to infect mostly the operating system administrator account, taking into account that from said account they can get all permissions and privileges that they need when having to modify each one of PC security protocols. By having absolutely everything control of the system same can hide itself and hide other malware who are working with him.
In addition, it should be mentioned that these types of elements of user mode start automatically every time the PC boots, so that restarting the computer to try to improve its operation will not be of much help. Some of antimalware security programs that are installed on the computers may be able to detect them, since said detection software I know plays at high levels of depthbetter known as .
Kernel mode rootkits
Realizing that the analyzers of these malwares at Kernel level they were given an answer then their creators decided to launch a new rootkits but this time kernel mode. These will find in the same operating system level on the machine, so their activity will compromise the entire operation of the OS.
East kernel mode is usually considered quite dangerous and advanced. This means that if your machine is affected by a rootkit from this there is basically nothing that can be done on your computer anymore, since everything will be found there pollutedincluding the results of antirootkit program scans.
An advantage over the kernel mode is that hardly this can act without actually causing a problem for your victimso its detection may be possible if malfunctions, blockages in the system begin to be generated, among other possible errors that indicate that there is an infection on the computer.
Firmware rootkits
for what you don’t know firmwares are a type of computer software which have as function control a piece of hardware in computers. By having this kind of function malicious people they made the decision to create malware that has the ability to hide inside these firmwares every time the user turns off the computer.
So that every time the equipment is turned on again, this element automatically it will reinstall and start working again. By working in this way it allows its removal is almost impossible or very difficult to achieve. If a antimalware program detects it during its operation and removes itautomatically to turn off the computer and turn it on again this reinstall.
in hybrid ways
Unlike the ones mentioned above, these harmful elements are not going to work from a only specific placebut some of them are going to run from user-level components and others through the kernel.
This means that those of hybrid modes will depend on the stability of user mode rootkitsbut this time they are being more empowered. It should be mentioned that this is one of the most popular rootkits among all users who carry out these activities. Due to its appearance in the affected computers is very frequent.
virtual rootkits
As its name indicates, they are based on a virtual machine What is it installed on a physical computer, are generally known as emulation softwares from a separate computer. And it is that you are Virtual machines are used by users to be able to emulate an operating system inside the computer.
They are mostly used for emulate mobile operating systems within a windows computerthis will allow the user to have several OS on his computer. One of the reasons for carrying installing emulators It is to test some programs, in the case of mobile OS for test applications created for them or for enjoy its functions but this time from the PC.
Nevertheless, virtual rootkits are based on these machine types, so it is load under the original OS and then enter the virtual machine system. Considering that they are going to run independently of the computer’s operating system, its detection is going to be very difficult to achieve. Furthermore, at work quietly the user will not be able to realize that he is being affected by this type of software.
Bootkits
Finally we found Bootkits or Rootkits Bootloader as they are also known, they are considered as a variant to those of kernel mode that infects the MBR of computers. This means that each time the computer performs a consult the MBR, the bootkits it will also load. It must be remembered that every time a computer is turned on, it will consult the register of main boot “MBR” this allows you to get all the necessary instructions on how to load the operating system.
So these elements decide to attack right at this point. Currently the programs antimalware are not able to detect bootkits or the possibilities of doing so are very minimal, as is the case with those of kernel modesince in these cases said malware is not found in The operating system. However, for Windows 10 users Bootkits they will no longer be a problemsince with the secure boot function the chances of infection are quite reduced.
Learn how to detect if there is a Rootkit on your computer quickly and easily
As it has already been mentioned previously in the post, be able to detect these malware is practically impossible, especially if they do their job properly. These are placed in The computers with the mission of commit illegal acts such as the extraction of information or private data. One way to try to stop these illegal activities is using a rootkit scanner, since this can be considered as the best alternative to try to detect and eliminate them.
There are also some ways that will allow you to know if there is a presence of them on your computer and which we will show you below:
The operating system of your computer works strangely
You have to remember that these malwares manipulate the entire operating system of the machine, so it is possible that it starts to work in a strange way to how it works normally. Therefore, if your team starts doing things that it shouldn’t, it is very possible that it is trying a rootkit.
Signature Analysis
It must be remembered that the operation complete of a computer is through numbereither all the data stored and executed on it, the files, all the programs,…
