Start runable c#!

[00niels00]

Hello, im creating my own launcher but i have 1 problem. If i do the normal way of starting a exe like this:

            Process theduel = new Process();

            theduel.StartInfo.FileName   = "theduel.exe";

            theduel.Start();

OR

            System.Diagnostics.Process.Start("notepad");

But it doesn't start when serialkey is enabled. I can make the serialkey disabled but thats not save becasue people can start without running launcher. Does some on have a way to start it when serialkey is enabled?

Irony, I'm reading a tutorial on C# right now.
You have the serial key code in your source?

 

[00niels00]

Whats the serialkey?
and how to add.

 

[Demantor]

Disable the launch serial key in runnable, its 1 address to change..

 

[shortymant]

there is no serial key in runnable.
edit: i think im wrong there, if there is no serial key in the runnable, how would it know when the serial key's been changed?
anyway, serial key is something like 25 chars, it tells it to open the runnable if those 25 chars are the same.

 

[Demantor]

Hit control + G and write "004972A7" :

You will see this:

[COLOR="Purple"]004972A7[/COLOR]  |.  [COLOR="DarkOrchid"]3D FFFF0000[/COLOR]   CMP EAX,0FFFF

Change it by hitting space, it will assemble at 004972a7, then write the red marked "MOV EAX,0FFFF"

[COLOR="Purple"]004972A7[/COLOR]      [COLOR="SandyBrown"]B8 FFFF0000[/COLOR]   [COLOR="Red"]MOV EAX,0FFFF[/COLOR]

Its also here on ragezone posted this edit..

See how the Laucnher uses the serial key to open/Launch the runnable, i have no idea, sry

I believe the launcher checks for certain values in the clipboard at certain times. "I_love_maiet", "I_hate_hacker" are what they used to be. Most likely above your level, but you could give it a shot.

Also, why not just use the official launcher?

Because i scripted anti-hack inside launcher it's very unstable but it's a start

The text has to have a certain timestamp.

The launcher uses a custom clipboard format so you cant see it unless you know the format ( its viewable through ollydbg ), and also the string is encrypted with the SEED algorithm.

Near the address that demantor have posted there is a lot of calls to OpenClipboard, IsClipboardFormatAvailable(theformatid), GetClipboardData and CloseClipboard.

 

[00niels00]

Ok i need to set clip board.

            Clipboard.SetText("I_hate_hacker", TextDataFormat.Text);
                System.Diagnostics.Process.Start("theduel.exe");

It doesn't work. Which format it has?

 

[Mr.Lucifer]

SetClipboardData(1378, THESERIALKEY);

 

[00niels00]

Ok i will try later. At which address in olly u can see the serial key?
I use xiao runable filelist skip. Whats the serial key in it?

 

[Mr.Lucifer]

It's not clear text... Read what Lambda said.

 

[Demantor]

Lambda in his server had made his Own Launcher, he knows all about Gunz, try asking him ^^

Do you know his msn? And was it scripted in c#?

Btw did any one here ever make a own launcher working.

I had my own launcher but i use other method to block the "double click run" on my GunZ exe, its more easy to use a mutex than emulate the GunZ way.

What would you say is the easiest solution among the two? Personally I have barely ever heard of mutex (dekker, spinlock or something, right?) myself. It sounds difficult.
