Not all hidden components detected
by anti-rootkit (ARK) scanners and security tools are malicious
. It is normal for a Firewall, anti-virus and anti-malware software, CD Emulators
, virtual machines, sandboxes
and Host based Intrusion Prevention Systems (HIPS) to exhibit rootkit-like behavior or hook into the OS kernal/SSDT (System Service Descriptor Table) in order to protect your system. SSDT is a table that stores addresses of functions that are used by Windows. Whenever a function is called, Windows looks in this table to find the address for it. Both Legitimate programs and rootkits can hook into and alter this table.
API Kernel hooks are not always bad since some system monitoring software and security tools use them as well. If no hooks
are active on a system it means that all system services are handled by ntoskrnl.exe which is a base component of Windows operating systems and the process used in the boot-up cycle of a computer. ARK scanners do not differentiate between what is good and what is bad...they only report what is found
. Therefore, even on a clean system some hidden essential components may be detected when performing a scan to check for the presence of rootkits. As such, you should not be alarmed if you see any hidden entries created by legitimate programs after performing a scan.
If you are using a CD Emulator
, Alchohol 120%
, etc) be aware that they use rootkit-like techniques
techniques to hide from other applications and can interfere with investigative or security tools. This interference can produce misleading or inaccurate scan results, false detection
of legitimate files, cause unexpected crashes, BSODs
, and general dross. This 'dross' often makes it hard to differentiate between genuine malicious rootkits and the legitimate drivers used by CD Emulators.
