Challenge of Reverse Engineering

Good day reverser ! I propose today a new crackme that has been created by me and Lollo90.Target : Silver : Create a patched executable; Gold : Create a patched,cleaned executable and reveal the correct password.Programming Language : Visual Basic .NETInfo The program was developed and protected by me and Lollo90. To test your username and your password you have to click the image on the right. A window will open, which will clearly show the success of the crack. At the start, and at the check of the password ,it can seem that is going to crash, wait some seconds and it will works perfectly.

I have made this little unpackme for themida.. its different than some themida unpackmes in that it was compiled in net framework v4.0 attached are two files one using x64 and the other is x32 bit the vb.net source Public Class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click MsgBox("Hello") End Sub End Class see attached rar file for packed themida.. lets see who can unpack it and if you do please post the result.. good luck! tuts4you.rar tuts4you_x32.rar

This is a crackme using vb.net the modified app should accept any key and say registered. if you crack it mention what tools you used! CrackMe.rar

Hello all, welcome to my first unpackme. It won't make your code smaller though, it's more of a protector. The attached file is a simple window. The goal is to restore the .exe to it's original transparent state, and if it were a real app it could then be reversed. Compiler: mingw Name: simple Difficulty: 1 or 1.5 / 10, no anti reversing/debug Feedback is welcome, do enjoy and thank you for reversing! SimpleUnpackMe.rar
