Some inject a dynamically linked library (such as a .DLL file on Windows, or a .dylib file on Mac OS X) into other processes, and are thereby able to execute inside a "rescue" CD-ROM or USB flash drive).[69] The technique is effective because a rootkit cannot actively hide its presence if it is not running.

Typically the malware loader persists through the transition to protected mode when the kernel has loaded, and is thus able to subvert the kernel.[36][37][38][39] For example, the "Stoned Bootkit" subverts the

Removal can be complicated or practically impossible, especially in cases where the rootkit resides in the kernel; reinstallation of the operating system may be the only available solution to the problem.[2] Rootkit detection is difficult because a rootkit may be able to subvert the software that is intended to find it.

But, while a rootkit might somehow be installed on a system through the use of a virus or Trojan of some sort, the rootkit itself is not really malware.


As of 2005[update], Microsoft's monthly Windows Malicious Software Removal Tool is able to detect and remove some classes of rootkits.[78][79] Some antivirus scanners can bypass file system APIs, which are vulnerable There are legitimate uses for rootkits by law enforcement or even by parents or employers wishing to retain remote command and control and/or the ability to monitor activity on their employee's For example, binaries present on disk can be compared with their copies within operating memory (in some operating systems, the in-memory image should be identical to the on-disk image), or the Obfuscation techniques include concealing running processes from system-monitoring mechanisms and hiding system files and other configuration data.[59] It is not uncommon for a rootkit to disable the event logging capacity of

Additionally, the compiler would detect attempts to compile a new version of the compiler, and would insert the same exploits into the new compiler. It loads its own drivers to intercept system activity, and then prevents other processes from doing harm to itself.

Rootkits and their payloads have many uses: Provide an attacker with full access via a backdoor, permitting unauthorized access to, for example, steal or falsify documents. By exploiting hardware virtualization features such as Intel VT or AMD-V, this type of rootkit runs in Ring-1 and hosts the target operating system as a virtual machine, thereby enabling the In Al-Shaer, Ehab (General Chair).
