Like kernel rootkits, these can reduce the performance of your RAM memory, by occupying the resources with all the malicious processes involved. Memory rootkits hide in the RAM memory of your computer. To make matters even worse, the rootkit might modify the boot records, and, by removing it, you risk damaging your PC.

As a result, antivirus and anti-rootkit software will have a hard time detecting the malware.
Since it attaches itself to those boot records, the rootkit won’t show up in the standard file-system view. This type of rootkit boots up at the same time as your operating system, by infecting the master boot record (MBR) or the volume boot record (VBR). And because they bury themselves so deep within the device, removal can be nearly impossible. The boot-up process is the second box that goes within the first box.Īs you can imagine, virtualized rootkits have even more control over your system than a kernel one. In a virtualized rootkit, the first box is the rootkit itself.The rootkit is the second box, that goes inside the first box. In a kernel rootkit, the first box is the boot-up process.To give you a visual sense of this, imagine the rootkit and the boot-up process as if they were two boxes. Security researchers developed the first such rootkit as a proof of concept in 2006 and are even more powerful than a kernel rootkit.Ī kernel rootkit will boot up at the same time as the operating system, but a virtualized rootkit will boot up first, create a virtual machine and only then will it boot up the operating system. Virtualized rootkits are a new development that takes advantage of new technologies. This proof-of-concept rootkit, for instance, managed to bury itself in the hard drive itself, and then intercept any of the data written on the disk. This then allowed them to intercept the credit card data and send it overseas. In 2008, a European crime ring managed to infect card-readers with a firmware rootkit. Instead of targeting the OS, firmware/hardware rootkits go after the software that runs certain hardware components. On a more positive note, a buggy kernel rootkit is easier to detect since it leaves behind a trail of clues and breadcrumbs for an antivirus or anti-rootkit. If the rootkit has numerous bugs and glitches, then this heavily impacts a computer’s performance. Kernel rootkits are advanced and complex pieces of malware and require advanced technical knowledge to properly create one.
#MALEWAREBYTES ANTI ROOTKIT CODE#
What this means is that the rootkit can effectively add new code to the OS, or even delete and replace OS code. This type of rootkit is designed to function at the level of the operating system itself. In this section, we’ll go through kernel rootkits, hardware & software rootkits, Hyper-V, and more. Of course, there are cases when malicious actors would manually exploit vulnerabilities before dropping a rootkit on the victim’s machine. Most are designed to automatically identify and exploit backdoors or, if none is present, rubber-stamp the installation process of legacy or deprecated software. Despite their overtly clandestine behavior, rootkits are only intended to bypass user authentication mechanisms before the arrival of a malicious payload (i.e., they often work in tandem with trojans or other types of viruses).Īs rootkits come in advance of various infectors, they do possess some degree of autonomy.
Rootkits are malicious computer programs designed to infiltrate a machine for the purpose of obtaining administrator or system-level privileges. In this article, we will discuss the functionality of a rootkit, go through classifications, detection methodologies, and, of course, rootkit prevention.
