WPBT is a fixed firmware ACPI (Advanced Configuration and Power Interface) table introduced by Microsoft starting with Windows 8 to allow vendors to execute programs every time a device boots. Rootkits are malicious tools threat actors create to evade detection by burying deep into the OS and used to fully take over compromised systems while evading detection. Security researchers have found a flaw in the Microsoft Windows Platform Binary Table (WPBT) that could be exploited in easy attacks to install rootkits on all Windows computers shipped since 2012.
