Recently, a new Worm/trojan has been very "popular" in the We Net world. This worm uses email and various phishing the WEB sites to spread and infect computers. When the worm breaks into the system, it installs a kernel driver to protect itself. With the help of the driver, it then injects and runs malicious code from the legitimate process "Services.exe". So, it can bypass firewalls easily and open a back door for the bad guys.
This worm contains an SMTP client engine and a Peer-to-peer client
suspicious processes including the network. this command displays all running processes and how they are started, including the original files that employ these processes.If attackers already have Super User Permissions, we may not be able to identify any suspicious activities because they often install rootkit immediately. rootkit can completely tamper with our environment, change important executable pro
6667, and the files associated with it (including deleted files) are included in the/tmp directory, it can be preliminarily determined that there is a problem with the program.
It is also important to check suspicious network activities because almost all attackers want to leave a backdoor so that they can easily connect to the victim's computer again. therefore, we can use the ps auxwf command to search for any suspicious processes including the network. this command displays all running proce
The Jiangmin anti-virus center has detected that among the new viruses recently intercepted by the center, more and more viruses have begun to deliberately hide their whereabouts (to hide them for a longer time ), the destruction process is completed without the perception of computer users. Experts especially reminded that computer users should guard against deeper and deeper attacks under the cover of virus and low-profile faces.

You can change the registration table's sensitive key valueUnknown module appears in the loaded module. Of course, if you replace the original DLL with the same name as the original trojan dll, you can avoidThe above problems, but there will be new problems, that is, how to bypass Windows System File Protection and administrator routineSystem File integrity check.Hxdef uses the hoo

Platform-independent environments such as OpenOffice.org, Perl, and Firefox are not spared. For example, Dropper. MsPMs-a malicious Java archive (JAR) file was found on machines running Windows, Mac OS X, and Linux.
Some malicious packages are specially written for GNU/Linux. Rootkit is a collection of tools that allow attackers to gain account access permissions from the root administrator on the computer. It is part
The development of the IT industry to now, security issues have become crucial, from the recent "prism door" incident, reflected a lot of security issues, information security issues have become urgent, and as operations personnel, it is necessary to understand some of the safe operation and maintenance standards, while to protect their own responsible business, The first thing to do is to stand in the attacker's shoes and fix any potential threats and vulnerabilities.Analysis of a post-Linux in

A rootkit is a tool commonly used by a class of people. This kind of tool is usually very secretive, so that users are not aware of, through such tools, the establishment of a regular system, or real-time control of the system. T

Rootkit from a superficial point of view is a self concealment of backdoor procedures, it is often an intruder as an intrusion tool. By Rootkit, intruders can secretly control the compromised computer, which is a huge hazard. Chkrootkit is a tool for searching the back door of a Linux system to detect rootkit.

Super backdoor Hackerdefender should be said to be well-known, and it is also a headache to scan and kill. Recently I found that www.sysinternals.com has a good tool that I don't dare to exclusive to write this article. The latest version of RootkitRevealer1.4 can be used to detect whether Rootkit is running in Windows. By analyzing the differences between the Registry and system API files, it can detect all rootkits released by www.rootkit.com, inclu
the process space of the browser, and the rogue software will be automatically called as long as the browser runs.Because the browser program itself calls a large number of DLL files, even if you use a third-party process to view the tool, you cannot tell which DLL is a rogue software. And because the rogue software using thread injection technology has been incorporated into the memory space of Normal programs, even firewall programs will not intercept, so that users can freely access and exit
How xti9erOSSEC checks netstat rookit is: Use netstat to view the port and bind this port for comparison.
If the port cannot be bind, it indicates that the port is occupied. If netstat does not find this port, it indicates that netstat is replaced by rootkit.
The idea is good. However, the difference between the two causes false positives. For example, some temporary ports are enabled after run_netstat, And the return value of conn_port is turn, a fal

Some methods in the http://www.la-samhna.de/library/rootkits/detect.html are worth reference, especially the last section To get a list of kernel modules, two standard methods can be used: In addition, one can look at the list of symbols exported by modules (/proc/ksyms), where the name of the corresponding module will be listed in square brackets, like the following symbol exported from the snd (sound) module: c85029f4 snd_task_name [snd]Unfortunately, being a kernel module, an LKM

different from other unlocking software in that it does not forcibly close the programs that occupy files, but rather unlocks the files and programs in a way that disconnects them, therefore, user data may not be lost due to forced shutdown like other unlocking programs.
The Unlocker installation is very simple. After downloading, you only need to double-click the file to install it. During the installation process, the program will allow the user to choose to integrate Unlocker directly into t

The main problem is that there are not many methods to Hook in Ring3, and the effect is not very good, because it is more "active" (Hxdef injects Trojan data into all processes in the system, it is easily discovered by Ring0 RootKit Detector, such as ICESWORD.
