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.

In my VMWare (32bit XP, .NET3.5 SP1) it tries to delete itself by running cmd.exe and ping.exe for delay. The same behaviour is very common in malware.

Considering that, there is no way I will run this shit on my real PC.

It autodeletes if you modify it. I am not posting a virus, if you want scan on virustotal or whatever yourself do it

Funny - I didn't change a single byte in it. I just launched it from C:\ using Windows Explorer.

@kao: Kao i would ask something, i  don't know if is possible: is possible that in some way the extracted file from the rar you downloaded has different md5?

No-one can do /wanna try it?

Why the hell would we try this...

 

hackforums already said the file is fishy...

 

now ill tell you why i think it is...

 

based on your screenshot its a simple login form with a few checks, yet upon downloading it the file size is 17MB

 

Why is it so big for such a small app???

 

This file clearly does something not mentioned in your post.

 

DO YOU THINK WE ARE STUPID

File connects to the net on startup:

 

www.frserver.altervista.org

 

Connects to:

 

http://www.frserver.altervista.org/CleanUp/CleanUp5.php

 

Then connects to:

 

http://frserver.altervista.org/CleanUp/__f.php

http://frserver.altervista.org/CleanUp/_f.php

 

 

 

Then to: (Data seems to be SSL cert info.)

 

http://frserver.altervista.org/CleanUp/_s.php

 

 

Didn't bother going further after seeing it attempt to connect to the net.

Yea at0mos you're right, it connects there to do antitamper cheks, and richyb look well on hf isn't a virus lol

@LoLLo90:
After unpacking it and entering a random name/password it gives me an message "PaneENuttella"

Is it normal? And what this means?

Codecracker congratulations! You did really a great job... but there is something you still need to fix.. the msgbox isn't completely correct:

in your exe it says(for other users except for me):

but it should exit to all users like this:

 

There is still another check you need to fix
