BYOVD involves adversaries writing to disk and loading a legitimate, but vulnerable, driver to access the kernel of an operating system. This allows them to evade detection mechanisms and manipulate the system at a deep level, often bypassing protections like EDR. For the exploitation to succeed, attackers must first ensure the driver is brought on the target system. This is followed by the initiation of a privileged process to load the driver, setting the stage for further malicious activities.
