What is a rootkit? Features of the rootkit
Nowadays when hackers have grown too strong, any host system despite how solidly could be compromised with many different sophisticated manner. During the approach, the rootkit intrusion system is a pretty dangerous stuff. The term "rootkit" became popular when the debate on the anti-piracy systems Sony music CD in 2005, they will automatically install a rootkit on the PC running Microsoft Windows, but users are not being consulted. What is a rootkit? rootkit-la-gi-dac-diem-crab-rootkit-may-chu rootkit is software or set of software tools to conceal the existence of the other software that virus usually enters the system the computer. Rootkits are often used after hackers gained access to computer systems. It will hide system data, files or processes running, so that hackers can enter a computer system that can not be known. A computer is installed rootkit called was "gaining root access." The term "rootkit" was initially used for systems using Unix toolset, it can carefully concealed traces of intruders for users who use the command "ps", "netstat", "w" and " passwd "to test, so it allows intruders to maintain" root "privileges on the system, even the system administrator can not see them. Nowadays this term is also used for Microsoft Windows when these same tools. Features of the rootkit rootkit-la-gi-dac-diem-crab-rootkit A key feature of the rootkit is capable of hiding up if Using the program from the system as: "Registry Editor", "Find Files", "Task Manager" can not be detected. Even though there discovered rootkit away, then delete it also is not simple at all. Can not use normal tools that must be used for anti-rootkit program special. Rootkits often operate at two levels is the application (user-mode) and the operating system kernel (kernel-mode) so detecting them is extremely difficult. The only negative for the system Rootkit Rootkit is often used to hide the tool for creating "back door" to help the hacker to access the system easier next time. Rootkit workers may have similar functions to create a back door. They allow the processes from ordinary users to implement the functionality for root. It hides all the different types of tools can be used to infringe system. The management system being infiltrated still unaware or consequences may bring the owner of the information, the data is extremely large, even in the long run. One of the best ways to avoid being infected with the rootkit was hired to host the virtual server from the service provider professionals to run the program as well as store important data. Many of us often think virtual servers usually safe, because everything is separate from the computer "all" physical, not directly related to each other. But Jason Geffner had discovered a flaw from the virtual server can be dangerous for the system, because the bad guys have access to other host systems running on the same host system via vulnerabilities. Security vulnerabilities are named VENOM (Virtualized Environment Operations Neglected Manipulation) attack on the virtual floppy code used as the basis for a number of virtual systems. Praiseworthy as VMWare, Microsoft Hyper-V and Bochs unaffected. Through vulnerabilities, hackers can penetrate other VM series and then access the server's network, and vital information can easily be stolen. VENOM not intervene to source virtualization software, but the attacker must obtain the highest authority (root) on the VM operating system. However flaws caused VENOM no serious damage but against this vulnerability causing much anxiety among software developers. Because previous security flaws often only detected in the virtualization software is not set by default and is not an official application, especially it does not affect the entire system. Therefore, VENOM can see the unique vulnerabilities so far, can alter the default configuration and host system, allowing the bad guys to run malicious destruction system directly. Because many platforms are built on the code of the virtual disk so even if you have turned off the virtual floppy drive still has 1 error help attackers turned on the virtual floppy drive, which means that vulnerabilities existed VENOM ago 11 years. Therefore, Geffner announced this to the relevant enterprises to quickly find directions fixes. If the system of your virtual server is running to meet this gap, you need to update the latest version of virtualization security today. Be safe maximum protection for virtual servers as well as servers that their real reason by updating your virtual servers to avoid unnecessary losses on physical servers.
