Rootkit Virus

A rootkit is more than a malware or virus. A rootkit cyber attack destroys the entire computer devices, operating system and the applications.

Therefore, it is necessary to understand the relationship between BIOS, user, application, operating system and the hardware devices, to absorb the sensitivity of a rootkit attack.

What is BIOS?

Bios stands for “Basic Input Output System”. A BIOS is a chip which is placed in a motherboard to start a P.C.

During a BIOS process, the connections of the hardware devices, operating system and the applications are validated to make sure there is no interruption and error.

A BIOS process checks the availability of the following hardware devices, operating system and the applications for a user prior to give a command to a user to use a P.C.

Motherboard: A combination of many hardware devices. It is a printed circuit board and a part of a P.C., where all the hardware devices are connected to, run a computer system, and we will name and explain each device below.

  1. CPU (Central Processing Unit) : A CPU is a chip not the entire “system unit or box” that is placed on a computer's motherboard to convert a user's raw data in a meaningful format. A CPU is a not a chassis, container or casing, rather it is a chip which extract results for a user.
  2. Keyboard: It is an external device which is connected to the motherboard to input data to convert in a meaningful format for a user.
  3. Serial Port or VGA Port : It is connected with motherboard to connect LCD, Projector and other display devices with the P.C.
  4. Parallel Port: It is also part of the motherboard and use to connect scanners and printers with the P.C.
  5. USP Port: It is connected to the motherboard and use to connect external discs.
  6. Lane Cable Port: It is also a part of a motherboard and use to connect your internet.
  7. Audio Port : It is used to connect the audio devices.
  8. CMOS Battery: It is part of a motherboard and use to adjust the time and date of your computer.
  9. Floppy Board: It used to be a part of motherboard to add floppy discs what is not used anymore.
  10. PCI Slot: It is part of the motherboard and use to add an extra modem hardware, sound card, video card, network card and other related devices.
  11. AGP Slot: It is part of a motherboard and use to add a graphic card to play high definition games.
  12. Heat Sink: It is used to absorb an unwanted heat in your motherboard.
  13. Ram Slot (Random Access Memory): It is part of your P.C motherboard and it enhances your workflow. It is a temporary memory of your system, that does not restore your data when it restart. The processor of your P.C directly demand for the data from RAM to process the activities.
  14. Power Connector: It supplies power to the motherboard.

Operating System:It is an application which is designed to manage your hardware devices and the applications that you use to get a meaningful output.

It is a manager of your P.C, that manages all the functions of your P.C. There are many types of operating systems, such as window operating system, android operating system, apple operating system, lynx operating system and many more. It is an interface between a user, applications and the devices. It is a combination of User + Application + Operating System + Hardware Devices.

An operating system process management, interruption, memory management, file system, drivers, networking, security and input and output.

Applications: The applications are your software that is installed on your operating system to shape your work in a readable or the understandable format.

Conclusion: A rootkit malware can damage your above mentioned P.C's hardware and software. So, it is highly recommended to use an effective antivirus software to find such vulnerabilities on them to protect your P.C from a damage
