Hi,
First of all i have to say " this is not my project and some friend ask me to upload challenge here "

Compiler : .NET

Protection :
[+] Binary Obfuscation

[+] Code Virtualization

[+] Anti-Debugging / Anti-Tampering

[+] Maybe some other protection

Rule :

Patch file to accept any password or find real password ( both accepted )
i will appreciate if you write something about you have done

Hint :
Run & Analyze file inside VM or isolated environment becuase of file isn't mine so i'm not responsible for anything
