Theef is definitely among the best hacking tools I have ever used. It is easy to use and intuitive, but best of all it gives you a great deal of options. This is why you will be learning to use it today.

Theef is a Windows based application for both the client and server end. The Theef server is a virus that you install on your victims computer, and the Theef client in what you then use to control the virus. The biggest problem with using Theef is that most Anti-Virus programs will pick it up. But with a little bit of social engineering you can generally get people to turn off their AV for you.

Before we begin you need to get a copy of Theef. I have uploaded a copy to Rapid Share here: http://www.ziddu.com/download/14394582/theef.zip.html.

So lets begin. First of all you need a target. This should be relatively easy to find, as I would imagine that the large portion of you reading this article already have someone in mind that you want to hack. If not, feel free to grab a second computer just so you can try this stuff out. For the purpose of this tutorial our victim is named TEST. And we are going to pretend that we are giving him an installer for a game called Theef Game.

Now you need to convince your victim to turn off their Anti-Virus if they have any. This is because Anti-Virus programs will generally pick up Theef as a virus and delete it. Convincing someone to turn off their Anti-Virus is not often a difficult task, most of the time you can just tell them something along the lines of, &quote;Your Anti-Virus says Awesome Game is a virus, but it isn’t so don’t worry about it.&quote; People are gullible, they want to believe you will cause them no harm, they want to trust you. Use this to your advantage.

The next thing we have to do is configure the program. This is an easy task to do. And to make it easier I will walk you through it using screen shots to help showcase the items you might want to change.

First make a copy of the Theef server. The Theef server is named Server210.exe. Name your copy of the server awesomegame.exe.

Now that we have a copy to work on we need to open up the editor. The server editor is named Editserver210.exe. Once it is opened you should be presented with a window that looks like this:

From here we need to open up our server for editing using the Load button. Once the server is loaded some values our to be filled into the boxes. The values on the first page can be left alone. In the forums I will be putting up a detailed list of what every option does, but for this tutorial we will only focus on what is needed to give TEST a virus.

To make it look plausible that Theef Game is indeed a game and not a virus we need to setup a false error message. 

To do this click Setup - False Error. On this screen check the box to enable false errors, then fill in the Input box labeled text with the following “The installer failed to run!” Your screen should look like this.

Now the server is ready to be saved and sent. Click the Save button to save the server configuration. The status bar should now say “Finished writing new server settings.” You may now close out of the server editor.

The next step is generally the hardest. You need to send the virus (in our case theefgame.exe) to your victim and get them to run it. Now for the purposes of our tutorial we have decided to send TEST a “game” by the name of Theef Game. Little does TEST know that Theef Game is not a game, but our virus. We have sent TEST Theef Game using Windows Live Messenger. If your victim is running Vista (like TEST is) then you will need to have them run the virus using Admin privileges.

Now that you have given them the virus the real fun can begin. From here we do everything in the Theef Client. This is the program that you use to control the virus. It is named Client210.exe. You should open it at this point.

You will need to get your victims IP address at this point so that you can connect to their computer. This is an easy task to do, and there are numerous ways to accomplish it. For our example we have convinced TEST to go to http://privax.us/ip-test/ and read his IP Address off to us from that page. We could also have gotten him to run ip-config or done any number of other things. If you have no idea what an IP Address is, just direct them to Privax’s IP Test and get them to send you their IP address off the page.

Using one of the aforementioned methods I have determined that TEST’s IP Address is 127.0.0.1 (please note your victim’s IP Address will differ from the address I have used in this example).

I now enter that into the IP input box on the Theef client and press Connect. If you have the correct address and they have run the virus you should see something similar to the following show up in the log box:

If you don’t have their IP Address correct or they have not run the virus you will see this instead:

Now that we are connected we can start to take do stuff. There are numerous features in Theef so I will only cover a small number of them here. I will likely cover more in the forums as time goes on. Also note that not all features of Theef work, and fewer features will work in Vista than in XP.

One of the most useful features of Theef is the key-logger, which is available under the Spy menu. Upon selecting it a key-logger window will open up as shown.

After you click the Start button on this window you will begin to see everything that they type on their computer. This is very useful as it shows you ever password they enter. It is a one stop shop to getting their passwords to everything and things such as their bank account numbers, etc.

There are other features in Theef that can be used for just screwing with people as well. Underneath of the Control Menu there is a button labeled Power. If you click that you will notice an Open/Close CD-ROM Drive button. Most people freak out if their CD-ROM Drive randomly opens and closes without them doing anything.

So this concludes my brief tutorial on how to use Theef. There is a lot more in this program that I covered here, but this should give you the basics on how to get started. Below I have posted two videos showing many more things that Theef can do. If you play these videos at the same time you can see how the client controls the server.

Thanks...
