Rootkits are programs that hide the existence of malware by intercepting and modifying operating system API calls that supply system information. Rootkits or rootkit enabling functionality may reside at the user or kernel level in the operating system or lower, to include a Hypervisor, Master Boot Record, or the System Firmware.1

Adversaries may use rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components.


  • Winnti Group used a rootkit to modify typical server functionality.2
  • HIDEDRV is a rootkit that hides certain operating system artifacts.3
  • Hacking Team UEFI Rootkit is a UEFI BIOS rootkit developed by the company Hacking Team to persist remote access software on some targeted systems.4
  • Uroburos is a rootkit used by Turla.5
  • Zeroaccess is a kernel-mode rootkit.6


Identify potentially malicious software that may contain rootkit functionality, and audit and/or block it by using whitelisting7 tools, like AppLocker,89 or Software Restriction Policies10 where appropriate.11


Some rootkit protections may be built into anti-virus or operating system software. There are dedicated rootkit detection tools that look for specific types of rootkit behavior. Monitor for the existence of unrecognized DLLs, devices, services, and changes to the MBR.1
