Is there a way to cause SciTE to crash?

[GGili]

Hello!
im new here.

i found that in this community i can ask all the dark questions and i very happy for that!

so this question nearly gave me eternal Ban in the normal autoit community..
i hope that here i can fell more free with my "Illegal" questions.


what i need to do is simple - I want to create a fake problem.
the fake problem will occur when the script detect that he was modified before / un-compiled .

the problem that i whant to create if the script detect that he was modified and un-compiled is that the script will cause SciTE to crash.


I want to achieve this protection..
I want to get some code for this.

thanks for helpers!

EDIT:
i don't need that you will write to me this part:

if the script detect that he was modified and un-compiled

i need code only for this part:

the script will cause SciTE to crash

doesnt seem dark to me... just script protection^^

but since all the time i used scite it never crashed, i think that scite runs stable.
but why crash scite? just add some lines, which let the script exit, or use an undefined array and obfuscate them. would also make the script useless. (unless the user knows how to deobfuscate, but then you cant do anything^^)

It is also a solution I had in mind.
But cause scite to crash is solution with pretty good benefits.

in scite you have console and the console can be used for debugging technique.

if i will craete fake error then the hacker can see what line cause the error because scite still running...

if the hacker do some debugging in scite while he runs the script, i want that he will can't use the information which provided in the console in scite.



so the solution is that the script will close scite.
but this solution is not perfect because the hacker realizes he should search for the command "ProcessClose" ..

you could also use this to terminate:

or create a recursion loop, which results in stack overflow. if the loop is complex, it would be hard to fix it.
or edit the script with controlsend, so the lines dont match anymore^^

what about using nomadmemory, to change many values. if i do this in games and change the wrong adress the game crashes^^
would be the hardest to spot i think, but you would have to deal with different scite versions.

i have something for you. it is called ASSP (Agressive Script Stealing Protection).
it works like that: you copy the entire content of the included files and add some lines between the include functions (or in functions that are often used in your script) that check if the script is compiled or not, or if the GUI window (if it exists) has the specified name or whatever and if the script detects an abnormal thing in your script then it will delete itself (because autoit only reads the au3 file once, closes it again and runs the autoit exe with that informations you can delete the au3 file) and will do whatever you want to happen (shutdown the computer, show an fake scite-has-stopped-working errormessage, earrape or whatever).

if there are many include lines (for example if you include GDIPlus.au3) and you put it somewhere in there (between 2 functions or in a function that you use much in your script) then noone will notice it and everyone will fail at stealing whatever type of program you did.

thanks for the suggestions.
But what will help me the most is how effectively hide the fact that exe file is autoit exe.

this is what i whnt to know now.

thank you!

it doesnt matter if someone or a decompiler and other programms know if this is a autoit .exe
