Firmware rootkits – These rootkits gain access to the software that runs devices, such as routers, network cards, hard drives or system BIOS.

Bootkits allow a malicious program to execute before the target operating system loads.

Bootkits – These rootkits gain control of a target system by infecting its master boot record (MBR).

In addition to being difficult to detect, kernel-mode rootkits can also impact the stability of the target system.

Kernel-mode – These rootkits are implemented within an operating system’s kernel module, where they can control all system processes.

User-mode rootkits are relatively easy to detect because they operate at the same layer as anti-virus programs.

User-mode or application rootkit – These are installed in a shared library and operate at the application layer, where they can modify application and API behavior.

There are a number of types of rootkits that can be installed on a target system.

For example, a kernel-level rootkit might use a loader that exploits a Linux vulnerability to replace operating system code with a rewritten Loadable Kernel Module.Įxample of a two-stage kernel rootkit injection Rootkit types The loader exploits vulnerabilities to ensure the rootkit loads together with the target system.

Loader – A loader is malicious code that launches after a user initiates the dropper program, either by opening or executing a file. Droppers can be distributed in a number of ways, including through social engineering or a brute force attack, in which a perpetrator uses a program to repeatedly guess a system’s root username and password.

This is achieved by combining the rootkit with two other components-a dropper, and a loader.ĭropper – A dropper is a program or a file used to install a rootkit on a target computer. In order to spread a rootkit, attackers form a blended threat to exploit several different vulnerabilities and infiltrate a system. Blended threatĪ rootkit cannot infect target computers on its own. However, hackers were able to exploit vulnerabilities in Sony’s rootkit to gain malicious access to the affected systems. The rootkit modified host operating systems and tried to prevent users from making copies of CDs. In 2005, Sony secretly bundled a rootkit with its Extended Copy Protection software, which came with millions of Sony CDs. When the administrator gives permission to install the software, the rootkit also silently installs on the computer. Users can unknowingly install rootkits that have been bundled with apparently trustworthy software. There are a number of ways that a rootkit can stealthily be installed on your system.

This grants attackers remote access, allowing them, for example, to use the computer in a botnet.

Remote access – Rootkits can alter system configuration settings, such as opening up backdoor TCP ports in firewall settings, or altering startup scripts.

File execution – After subverting anti-malware software on a system, rootkits allow perpetrators to remotely execute other files on target computers.

Eavesdropping – Hackers can use rootkits to eavesdrop on users and intercept their personal information.

File deletion – Rootkits can delete operating system code or other files on a system.

Information theft – Malicious software installed with the aid of rootkits can be used to steal user passwords, credit card information, or other sensitive data without being detected.

They hide malicious programs from users and any anti-virus software installed on a computer.

Concealed malware – Rootkits allow attackers to install additional malware on infected computers.

Potential consequences of a rootkit include: There are, however, rootkits that can boot up before the target operating system, making them very difficult to detect. Once installed, a rootkit typically boots at the same time as the computer’s operating system, or after the boot process begins.

Simply put, it is a nasty type of malware that can severely impact your PC’s performance and also put your personal data at risk. A rootkit is a software program, typically malicious, that provides privileged, root-level (i.e., administrative) access to a computer while concealing its presence on that machine.
