Adversaries may use rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components. Rootkits are programs that hide the existence of malware by intercepting/hooking and modifying operating system API calls that supply system information.[1]

Rootkits or rootkit enabling functionality may reside at the user or kernel level in the operating system or lower, to include a hypervisor or System Firmware.[2] Rootkits have been seen for Windows, Linux, and Mac OS X systems.[3],[4]

Rootkits that reside or modify boot sectors are known as Bootkits and specifically target the boot process of the operating system.
