#Fud crypter update
!!Important!! If you want to test your crypted exe with online AVs, do it only here ( ) and don't forget to check the checkbox "Do not distribute the sample"! Otherwise your exe will be distributed to the AV companies so they can exermine it and update their virus databases.ĥ. Cybergate: 290KB (before), 327KB (after) Poison Ivy: 10KB (before), 46KB (after) I don't know if this also works for Vista and 7.

(other tools might also work with this technique, just test with your exe) Cybergate server (v1.07.5) (Hint: "Compress with UPX" must be disabled) Maybe these ideas are not new to you and someone else posted them already here somewhere. In this tutorial I'm going to explain how you can implement your own crypter and how you can play around with the code to get your exe FUD again if it gets detected some day.

So I figured out a way to write my own crypter in C++. But the problem with those crypters is that they get detected very soon after they were published. I guess most of the public available crypters do it similarly.

I'm not going to explain a completely new method of how executables can be made FUD. Please, Don't abuse this tutorial, Use it wisely. This tutorial is strictly for educational purposes only, I am not responsible for any of the action you may take upon others.
