A rootkit is a malicious software that allows an unauthorized user to have privileged access to a computer and to restricted areas of its software. Choosing to infect the boot records also makes them less vulnerable to detection or removal since most antivirus software programs are not designed to focus on boot records when scanning for malicious code. The first rootkits for Windows were detected at the turn of the century, with some of the most notable examples being Vanquish, which recorded the victims’ passwords, and FU, which worked in kernel mode and was used to modify the structure of the system rather than just the ways to access it.

For example, a loadable kernel module (LKM) rootkit can be utilized to monitor and report activities on the ECU, after the attacker gets inside an ECU. Memory Rootkits. rootkits do not affect the operating system and are therefore even more difficult to detect than kernel-level rootkits. 3. It serves as an intermediate connector between the application and the hardware. A rootkit is a clandestine computer program designed to provide continued privileged access to a computer while actively hiding its presence. Rootkit can also be taken as a part malware that may be able to hide it from your eyes on your computer and secretly provides entry to unauthorized accesses. 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. Most rootkits, however, were developed by unknown hackers with the goal of compromising the victims’ computers and obtaining their sensitive information for personal gain (mostly financial) of the hackers. A good example of a kernel mode rootkit is the Zero Access rootkit of 2011.

The BIOS (basic input/output system) is firmware that resides in memory and runs while a computer boots up. Rootkits provide attackers with continued access to infected systems. As the name suggests, these rootkits target the memory of a computer system. Kernel mode rootkits are a little bit trickier to detect. Hackers can install rootkits on the target machine in many ways, but most of them involve a phishing attack or some other type of social engineering.
