Rookie introduction: Trojan in the system hiding point

1, integrated into the program

In fact Trojan is also a server-client program, in order not to allow users to easily delete it, it is often integrated into the program, once the user activates the Trojan, then the Trojan file and an application bundled together, and then uploaded to the server to cover the original file, so even if the trojan was deleted, As long as the application bundled with the Trojan, the Trojan will be installed up. Bound to an application, such as binding to a system file, every time Windows startup starts a Trojan.

2, hidden in the configuration file

Trojan is too cunning, know the rookie is usually using the graphical interface of the operating system, for those who have not very important configuration files are mostly indifferent, which just give a trojan to provide a hiding place. And the use of the special role of configuration files, Trojans can easily in everyone's computer run, attack, and thus peeping or watching everyone. However, now this way is not very covert, easy to find, so in Autoexec.bat and Config.sys loaded Trojan horse program is not seen, but also can not be taken lightly oh.

3, lurking in the Win.ini

Trojan Horse to achieve control or monitor the purpose of the computer, must run, however, no one will be silly to their own computer to run the damn Trojan. Of course, the Trojan is also early psychological preparation, know that human is a high IQ of animals, will not help it to work, so it must find a safe and can be in the system, start automatically run the place, so lurking in the Win.ini is a trojan feeling more comfortable place. You may wish to open Win.ini to see, in its [Windows] field has the start command "load=" and "run=", in general, "=" after the blank, if there is followed by the program, for example: Run=c:\windows\file.exe Load=c:\windows\file.exe, at this time you must be careful, this file.exe is probably a Trojan oh.

4, camouflage in the ordinary document

This method appears late, but it is now very popular, for unskilled windows operators, it is easy to be fooled. The method is to disguise the executable file as a picture or text--in the program, change the icon to Windows Default Picture icon, and then change the file name to *.jpg.exe, because the Win98 default setting is "Do not show known file suffix name", the file will appear as *.jpg, People who don't pay attention to this icon is a Trojan horse (if you embed a picture in the program is more perfect).

5, built into the registry

The above method makes the Trojan really comfortable for a while, no one can find it, and can automatically run, it is fast! However, the long time, the human quickly took it out of the hand, and it was severely punished! But it is also unwilling, summed up the failure of the lesson, that the above hiding place is very easy to find, now must hide in not easy to find place, so it thought of the Registry! Indeed, due to the complexity of the registry, Trojans often like to hide in here merry, quickly check, what procedures in its next, open eyes carefully look, do not let off the Trojan Oh:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

A key value that starts with "run";

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion

Next all key values that start with "run"

Hkey-users\. Default\software\microsoft\windows\currentversion

All key values that begin with "run".

6, hiding in the System.ini

Trojan Horse is really everywhere! Where there is a loophole, where it is drilled! This is not, Windows installation directory under the System.ini is also a trojan like hidden place. Or be careful, open this file to see if it is different from the normal file, in the [boot] field of the file, is there such content, that is Shell=Explorer.exe File.exe, if there is such content, then you are unfortunate, because here File.exe is the Trojan server program! In addition, in the [386Enh] field in System.ini, be careful to check the "driver= path \ Program Name" In this paragraph, it may also be used by Trojans. Again, in the System.ini [mic], [drivers], [drivers32] These three fields, these sections are also played to load the role of the driver, but also add Trojan program good place, now you should know also to pay attention here.
