For example, Realtek-based routers and smart devices were being gobbled by a voracious botnet thanks to a software flaw.

But hackers can take advantage of firmware vulnerabilities to hijack hardware. No, firmware from your device’s manufacturer is certainly not a virus. But completely deleting firmware will brick your device. If you roll back a firmware update correctly, your device’s firmware should go back to an older version. Or how all computer viruses are malware, but not all malware are viruses. All firmware is software but not all software is firmware, much like all iPhones are mobile devices, but not all mobile devices are iPhones. The difference between firmware and software is that firmware is simply a type of software. What is the difference between firmware and software? The 'firm' in firmware refers to the fact that it is embedded into hardware and is not intended to be easily changed or modified, making it more 'firm' or 'fixed' compared to traditional software. Why is it called firmware?įirmware is called as such because it is a combination of 'firm' and 'software'. According to our Malwarebytes Labs firmware definition, these files are written to the hardware device’s memory. Like the one found in some digital cameras, some firmware can also be the primary operating system. So, what is firmware, and what does it do? Firmware is software embedded in hardware that allows it to function as intended and provides manufacturers low-level control.

Its primary purpose is to ensure the reliable and efficient operation of the hardware it is embedded in, and it plays a critical role in the overall performance and functionality of the device. Firmware can be found in a wide range of devices, from consumer electronics like smartphones and smart home devices to industrial equipment and automobiles. It serves as a bridge between the hardware and software layers of a system, allowing the hardware to interact with the operating system and applications. Unlike traditional software, firmware is not designed to be modified or updated frequently, and it is typically stored in non-volatile memory. Firmware is a type of software that is embedded into hardware devices to control their functionality.
