How to Perform a Linux Rootkit Detection Problem?

Linux rootkit detection has been made easy with the recent development of Linux kernel patches. The kernel is a complex part of any Linux operating system, and it is not uncommon for bugs to be found in the kernel that allow malicious programs to execute code within the kernel and do harm. Linux itself has had several security issues in the past, including the “Plesk Panel Bug” that was found and fixed in 2001. One of the more common problems is the “kernel panic” bug that shows a series of different panic messages, causing computer users to lose control over their computers. Some of these bugs are so severe that they can even cause an airplane to crash. Fortunately, the latest Linux patches have taken these problems and fixed them, allowing Linux users to continue using their computers safely.

There are two common ways to get rootcheck results. The first way is done manually and involves analyzing the boot up logs of the computer, looking for the occurrence of the linux-agent kernel module. When the Linux kernel detects the linux-agent kernel module during the boot up process, it will try to load additional modules into the kernel, including the rootkit. If the rootkit is loaded successfully, the program exits with an error message.

Linux rootkit detection:

The second method that Linux users can use for the purpose of finding rootkit is by using an online Linux utilities. One such utility that can be used is the Linux Rootkit Detector. This utility has been programmed to search for patterns, or anomalies. Whenever the Linux kernel returns a response of an error. Whenever an instance of the Linux rootkit exists in the system, this utility will search for the specific pattern or anomaly that has caused the problem. Each time the utility searches, it will print a progress message on the screen, which will let you know whether the rootkit has been detected.

The Linux Rootkit detector can be used to scan for any possible kernel level rootkit, and even detect if a specific rootkit is loaded into the system. The advanced version of this utility has a built-in database. With this database, all the past activities of users in the same computer (including their login name and passwords) are stored. Using this database, it is possible to search for anomalies, and trace whether they are rootkits or not.

Aside from being used to detect rootkit events. The Linux Rootkit detection can also be used to debug other performance issues on your system. The following events that the utility can debug are kernel crashes, hung processes, and busy signals. The following commands can be executed to debug the Linux Rootkit Detector.

To debug the Linux Rootkit Scan Method, the command that you will use is “rootcheck -d”. The Linux Rootkit Detector will start to debug the process that has crashed. By pressing “ctrl+f” you can then view the debugging output. However, this is just a basic mode for the utility. More complex operations such as debug logging or detailed events recording will require rootcheck to be switched to the “full” debug mode.

Using the rootcheck tool:

To debug the Linux Rootkit Checked Process Method, the following command line should be entered: “rootcheck -c”. The “c” stands for ‘configure’. In this instance, you will be telling the utility to configure the Rootkit detector. When you switch to the configuration manager, you will be able to see the various options that you can change. Some of these options include disabling or enabling modules. To disable modules, you will have to enter the following command: “rootcheck -c”, where “c” is replaced with “enable”.

It is important to reboot your computer and disable the detected application. When the above, Linux rootkit detection method is used to find and remove the rootkit. Normally rootcheck will not be completely removed if the problem was not serious enough to disable the application. You may however need to temporarily disable the application in order to allow the removal of the rootkit files. To restart your computer after the removal of the rootkit. You will need to enter the following command: “shutdown -r now” and then press enter. Rebooting your system will ensure rootkit detection in future processes.
