Yes, an attacker with write access to boot already compromised the entire OS and data. Usually replacing the storage or reinstalling the OS would get rid of the attacker. But this exploit happens early in the boot process, before the OS even loads.

This means the only way to ensure a network remains uncompromised after an attack is physically destroying any infected devices or replacing their mainboard.

There are major benefits to this approach. One is that no executable code ever touches the hard drive, a technique known as fileless malware that hampers detection by antivirus and other types of endpoint protection software. Another benefit: Once the image is in place, it ensures a device remains infected even when an operating system is reinstalled or the main hard drive is replaced.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
