5. BACKDOOR: this is an image metaphor. After using some methods to successfully control the target host, intruders can implant a specific program in the system of the target host, or modify some settings. on the surface, these changes are hard to detect, but intruders can use appropriate programs or methods to easily connect to the computer and re-control the
If you installed in the computer Kaspersky antivirus software, it is possible to encounter the opening of the site, the site is blank, and the site after the address is followed by the 1x1, and after a number of browsers, is still so, then this is how it? Encountered open the site is blank, how to deal with it? Take a look at today's Kaspersky user opens a Web site with a blank solution.

When talking about Trojan horse or Trojan activity, there are two frequently used terms. The identification methods and explanations are as follows:

Usually, after the intrusion is successful, one or several backdoors will be left for re-entry. For Unix/Linux systems, there are many types of backdoors and there are some preliminary modifications. rhosts file, copy a Shell to a hidden directory, modify the etc/passwd file and add the user.
