    The less specific, the more challenging.

    I won't tell you what to do...

    BUT!

    I can give 1 clue:

    I love assembly!

    BTW I know not everyone can understand what's in, but if you have enough logic, you will get.

    You just need to know that in the original program, the .data's in the beginning were coupled with the alphanumeric codes just after those liines of code beginning with .data, wich are used later in the program.

    EDIT: Visibly, there are missing data's in the debbugging, wich proves taht it refers to alternate programs, wich can be used to debug the original programmation language of this.
    I mostly believe it's C++, since strings are "decompiled" in hexadecimal instead of db "" strings format.

    Ah, and this is a x64-bits program.

    Wait... You're shitting me right? Sheild's original post is of an encrypted 7z, unless this one is different from the one he gave us in chat last night...

    Or is it that you are refering to your pastebin. In that case I'm even more as to how you concluded that this is a executive when the magic numbers are definitely not that of an executable file.

    EDIT: Ninja

    Ok so I'm the only one understanding that the .datas at the beginning are just compressed datas (or sort of plots to make data go into certain positions in the 7z).
    Then that the rest of the code is mainely the way to decode password ?
    That's why the code begins without any declaration of a program part, it is on it's own!
    If you go into a professional disassembler, then you'll get that the datas at the beginning are in black or grey probably:
    it refers to non-coded datas, but only to ROMs!
    So now that you have this pastebin I made, if you well search, there's the encryption in it!
    It doesn't mean there is the direct password, but there's the encryption, wich could be used to decrypt then.

    I just want to make it more challenging through making you search the way I do!

    EDIT: I though it was in C++, as real, this program is in the same language than 7z!

    And yes, compressed archives are active on bytes, but to "execute" them, you must use 7-zip!

    someone's getting close.... ;D Also, this is just level 1. I have about 16 more levels of encryption that will go on the real contest file.

    I got the data's and the order to place...
    But bullshit! I'm too lazy...
    You also have the data's, just focus 5 minutes.
