Thus, the first rule of security all employees should learn when they’re granted access to corporate computers is never to open attachments in emails from unknown senders and only to download or install software approved by the IT department (preferably from an IT-provided download or shared file).

The most common infection mechanism is to trick an unsuspecting user to download and install a file or program of some kind (e.g., an image, an executable file, a PDF file, a macro, and so forth), often from a website or an email attachment. Like any other program, a rootkit requires user interaction or system compromise to take up residence on a PC. If a call involves any data that might reveal the rootkit to a user, it will be hidden or supressed, so the user sees nothing alarming or out of the ordinary. And because it can access the OS kernel and its APIs, a rootkit can hide itself by intercepting any system call that includes a filename or any other data that might reveal its existence. This means a rootkit can run everything from keyloggers to backdoors. It makes itself “persistent,” which means it activates every time a user boots the PC. Such a rootkit modifies the Windows kernel. That’s what makes any kernel mode rootkit so dangerous and so difficult to detect and remove. Thus, kernel mode rootkits essentially operate as if they were part of Windows itself. Privileged programs and the operating system run in kernel mode, which can make direct access to operating system resources and can interact directly with other operating system services. (The most renowned rootkit, Hacker Defender, is an example of a user mode rootkit.) In the Windows operating system, ordinary programs run in user mode, which can only make mediated calls on operating system services and resources. Generally, rootkits can be divided in two categories: user mode and kernel mode.

The term rootkit is a concatenation of ‘root’ (the traditional name of the privileged account on Unix-like operating systems) and the word ‘kit’ (which refers to the software components that implement the tool).” Please note that the term “tool” in the previous sentence refers to the rootkit itself and reflects the increasing tendency for malware creators to make use of code libraries and various other kinds of programming building blocks to construct such things, including rootkits. Wikipedia defines a rootkit as “a collection of computer software, typically malicious, designed to enable access to a computer or areas of its software that would not otherwise be allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.
