RE: AutoIt Decompile

AutoIt version of DUmp__AllowExec.exe is:

With problems like this first of all get the SCRIPT.a3x from the script.
(use 7-zip or some other resouce extract tool to get DUmp_.exe\.rsrc\0\RCDATA\SCRIPT)
Well I tested the SCRIPT.a3x with the following autoit3.exe
3.3.12 and

only the green | blue ones worked.

Target is Garena Cracker 1.3
[Image: garenacracker_1.3_dezezusy.png]
compiled byfarid on 19.12.2014 19:31:17 on AutoIT

What it does is basically running for example:
C:\Program Files (x86)\Garena Plus\bbtalk\BBTalk.exe -login cw2k17 403c0314f89857402b2863e97ed9e3d5 -md5 -ignoreupdate -multiinstance
for testing if certain combination of from usernames.txt & password.txt is correct.
  • To find \bbtalk\BBTalk.exe correctly the script need to be copied and run from C:\Program Files (x86)\Garena Plus
  • without -md5 password can be also passed in clear text
Well unfortunately BBTalk.exe 1.2.40 has some bug that makes it hang if you enter an invalid password or usename. (I just only once made it say invalid Login)

furthermore there's some subtile change the au3 code:
  • PHP Code:
    is WinGetClientSize()  width=360 and height=277 
    used to trigger if login succeed need to be updated. to width=100 and height=50
  • also the function that uses WinList("Garena Talk (Beta)") to look for the invalid Login windows needs to be changed to WinList("TalkTalk (Beta)") to successfully fulfill its task
However that kind of implement might work - but don't complain it's wacky and slowDodgy

And there's already a newer Version
Garena Cracker 2.5

[Image: garenacracker_2.5_novxgulm.png]
compiled byfarid on 08.11.2015 08:00:43 on Autoit

beside 2.5 the only link one that is also still working on is GarenaCracker-2.3-Setup.exe

The cool thing about Version 2 is that it uses direct communication via curl with (<- url is now different) which is more direct fast and stable.
(Well next step would be to make it multithreading so you can slam many checks in parallel - how I don't wanna complain)

It has some little strange and stupid check to see if it's compiled or a script.
  • from Libraries\Libraries.dll!DllEntry via IDA 6.8 hexrays
    PHP Code:
    BOOL DllMain(HINSTANCE hinstDLL ,...

    // is Garena Cracker running
    if ( OpenMutexA(0x100000u0"Garena Cracker: Running");)

    // get 128 bytes from GarenaCracker.exe (seek 0x2000 from the End Of File)...
    GetModuleFileNameA(0, &Filename0x104u);
      if ( 
    fopen_s(&File, &Filename"rb") )
    fseek(File, -0x2000uFILE_END)
    // ... Compare Buffer with 0x80 Bytes from this Dll
    if !<Compare  succeed>

and this Libraries.dll has 2 important exports
  • GetPackets(_DWORD *aOutBuff) these are important configuration data for sending and check the receive packets to check login
    => can be replace by just hardcoding them:
    PHP Code:
        $MessageType     0x020A    ;DllStructGetData($tBuffer"p1")
    $Unknown1         0x1220    ;DllStructGetData($tBuffer"p2")
    $Unknown2         0x180122013128E44F;DllStructGetData($tBuffer"p3")
    $Receiv_1         0x020A    ;DllStructGetData($tBuffer"p4")
    $p5_Case1         0x200801    ;DllStructGetData($tBuffer"p5")
    $p5_Case2         0x200802    ;DllStructGetData($tBuffer"p6"
  • MD5(BYTE *pbData, BYTE *MD5) to create md5 hash from the password.
    = > Well Autoit can also create MD5 beside the official Crypt.au3 _Crypt_HashData() way here's an other undocumented one:
    PHP Code:
    #include <WinAPIDiag.au3>
    Func MD5($Base$Data)
    end Func 
so by this that dll can be removed completely

What also is a little weird is the way it load it's picture resources. Normal you do this in autoit via Fileinstall however here it adds the pictures directly into the exe -
resources uses and uses _WinAPI_LoadResource(). For script it just performs _GDIPlus_ImageLoadFromFile() to \Resources\*.png

Interesting is the way on using and introducing some kind of OOP classes to Autoit that are heavily based on arrays.
The whole thing is called AutoItObject in the end you can code things like this:
PHP Code:
$Msg.Information("Cracking successfully finished."$Main
the '.' is not really new in programming but for AutoIT that is mostly just 'functions base' its kind da uncommon.

Well enough writing soon I'll release here the more (or less) finished script
