Anti Rootkit – Best Rootkit Virus Scanner, Checker and Removal Tool

What is Rootkit?

A rootkit is a class of program intended to cover the fact that a system has been compromised.

Rootkit authorizes virus and malware to stow away from being recognized, by disguising it as important windows file which allows it to bypass the system firewall and stay hidden from any security program.

Rootkits themselves are not destructive; they are just used to cloak malware, bots, and worms.

Rootkits get their name from the Unix appearance of its administrator account called "root" and "packs," which refer to the software pieces that execute the tool.

To introduce a rootkit, an attacker should first access the root directory by utilizing an exploit kit or getting the password by breaking it or via social engineering. Hence, always keep your PC updated with a Rootkit scanner and remover!!!

Rootkits were first seen in the mid-1990's and originally worked on UNIX operating system. Today, rootkits are prepared for many other operating systems, including Windows. Since rootkits initiate before the PC even boots up, they are particularly hard to identify and therefore provide a dominant way for attackers to access and use the target computer without being noticed.

Because of the way rootkits are utilized and introduced, they are hard to eliminate. Rootkits today usually are not used to gain access, but instead, are being used to cover malware payloads more efficiently.

Techniques used to spread Rootkit Virus

A rootkit virus can install itself automatically, or a hacker can authorize its installation once they've gained administrative rights or root of the system.

Gaining such access is a result of a personal attack on the system, i.e., overriding a known vulnerability or the system password (acquired by cracking or social engineering tactics like "phishing").

Once installed, it becomes possible to cover the infections on the system as well as to control administrative access. The key is the root or administrator access.

Full control over a system means that existing software can be modified, including programs that may be some way or another be utilized to distinguish or evade it.

Behavioral-based Identification

The behavioral-based approach to detecting rootkits attempts to indicate the appearance of a rootkit by watching for rootkit-like function. For example, by profiling a system, variations in the timing and frequency of API calls or in overall CPU utilization can be associated to a rootkit.

The process is complicated and is hindered by a high percentage of false positives. Incomplete rootkits can sometimes inject very obvious changes into a system: The Alureon rootkit crashed Windows systems after a security update revealed a design defect in its code.

Logs from a packet analyzer, firewall, or intrusion prevention system may present evidence of rootkit behavior in a networked environment.

Discovering Rootkits from memory Dump

Constraining a total dump of virtual memory will catch a dynamic rootkit (or a part dump on account of a kernel-mode rootkit), permitting an offline experimental investigation to be performed with a debugger against the following dump file, without the rootkit having the capacity to take any measures to shroud itself.

This procedure is profoundly particular and may expect access to non-open source code or debugging symbols.

Memory dumps launched by the operating system cannot always be utilized to recognize a hypervisor-based rootkit, which can capture and subvert the most minimal level trials to read the memory—a hardware device, such as one that implements a non-maskable interrupt, might be required to dump memory in this situation.

Virtual machine likewise makes it simpler to break down into the memory of a compromised system from the hidden hypervisor, due to which some rootkits will avoid infecting virtual machines.
