The first binary version of BO2K was compiled and spread in the US. A few days later there appeared an international version of this backdoor. With the time there may appear lots of versions of BO2K with different compilers and having different features. As its previous versions, the Back Orifice 2000 backdoor has 2 major parts: client and server. The server part needs to be installed on a computer system to gain access to it with the client part. The client part connects to the server part via network and is used to perform a wide variety of actions to remote system.

The client part has a dialog interface that eases the process of hacking of the remote computer. Here's the screenshot of the client part. In the same package there comes also a configuration utility that is used to configure the server part of BO2K. Minecraft Hd Texture Pack 512x512. By default the server part doesn't install itself to system being run. It should be properly configured to be used as a backdoor.

Does Bridgehead Have Wifi. The configuration utility has a wizard that helps to quickly configure the server part. It asks the user to specify networking type (TCP or UDP), port number (1-65535), connection encryption type - simple (XOR) or strong (3DES) and password for encryption that will be the password for the server access also. Here's the screenshot of the BO2K configuration wizard. The configuration utility allows to flexibly configure the server part. It can add or remove plugins (DLLs) from the server application, configure file transfer properties, TCP and UDP settings, built-in plugins activation, encryption key, and startup properties.

The startup properties setup allows to configure automatic installation to system, server file name, process name, process visibility and also NT-specific properties (NT service and host process names). Here's the screenshot of BO2K configuration utility. When the server part is configured to act like a trojan i.e. To install itself hideously to someone's system it writes itself to Windows System or WinNT System32 folders under a name specified during configuration (default is UMGR32.EXE).

Then it modifies the Registry. Under Windows 95/98 server execution string is written to: HKEY_LOCAL_MACHINE Software Microsoft Windows CurrentVersion RunServices under Windows NT the execution string is written to: HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows CurrentVersion Run Then the file from which the server part started can be deleted (if it was specified during configuring). After that the BO2K will be active in memory each time Windows starts and will provide access to the infected system for hackers who have the client part and the correct password. Being active the server part can hide its process or prevent its task to be killed from Task Manager (on NT). The backdoor uses a smart trick on NT by constantly changing its PID (process ID) and by creating the additional process of itself that will keep the backdoor alive even if one of the processes is killed. Besides, the server part adds a random (but large) number of spaces and 'e' at the end of its name, so the server part file can't be deleted from Windows (invalid or long name error occurs) though disk checking utilities don't find any problems with filename. The server part file can be only deleted from DOS or DOS session (if the file is not locked of course).

Back Orifice 2000 like its ancestors has a lot of features. Download Beamng Drive Keygen. But unlike the older versions the BO2K has many improvements: connection encryption (including strong 3DES), ability to work under NT, to use UDP, to allow internal plugins in DLL format, a more advanced security, more remote system control features.
