What Is BIOS Rootkit?

The term "Basic Input/Output System" is referred to by the abbreviation "BIOS." This form of firmware, which is embedded in the motherboard of a computer, is responsible for controlling both the process of initializing the hardware of a computer and starting the computer itself. A rootkit is malicious software intended to hide its presence from the operating system and allow unauthorized access to a computer system. Its primary function is to prevent unauthorized users from accessing the system. Its primary purpose is to enable an adversary to obtain administrative responsibilities within the system. One type of malware is known as a BIOS rootkit, and it is distinguished from other rootkits because it conceals itself within the firmware of a computer's BIOS. It demonstrates that it can function lower than the operating system, making it more challenging to discover and eliminate. The primary purpose of a BIOS rootkit is to simplify the process of gaining remote access to and conducting eavesdropping on a computer system. System administrators and original equipment manufacturers can directly access and update a system using this feature. However, this can also be exploited maliciously to obtain unauthorized access to a system, which can make it helpful for maintaining and troubleshooting a system in certain circumstances. The fact that a BIOS rootkit is stored in the computer's physical memory and can be retrieved from that location is one of the essential aspects of this type of malicious software (RAM). It suggests that it is still there even after the operating system has been reinstalled or after the hard drive has been thoroughly wiped clear. To summarise, a BIOS rootkit is malicious software that can generally be difficult to detect and remove entirely from a computer system. Since it is stored in the computer's firmware, it is preserved even after the operating system has been wholly reinstalled, even though it enables remote access to the system and surveillance.
