Posted: Fri Jun 06, 2014 4:37 am Post subject: Need help disabling this script.

Code:

[enable]
alloc(mem,1024)
registersymbol(mem)
createthread(mem)
mem:
mov eax,[01005194]
lea eax,[eax+1]
mov [01005194],eax
push #1000
call sleep
jmp mem
[disable]
mem:
ret
unregistersymbol(mem)
dealloc(mem)

In this script,I need the 'ret' to execute before the dealloc command,because the ret will kill the thread,if I could make the 'dealloc(mem)' execute one second after the other part of the script,it would solve the problem,also,I did not use globalalloc because there is no 'globalfree' command like in MHS,and as I know,there is no lua command to kill target threads,is there?
Also,what is the heaplist?what kind of useful informations can I gather from it?

globalalloc is specifically used for cases like this. You do NOT want to free it

Code:

[enable]
globalalloc(mem,1024)
registersymbol(mem)
createthread(mem)
mem:
mov eax,[01005194]
lea eax,[eax+1]
mov [01005194],eax
push #1000
call sleep
jmp mem
[disable]
mem:
ret

this way you can toggle it on and off without it allocating more memory each time (globalalloc reuses the memory block)

in 6.4 you can do:

Code:

[enable]
alloc(mem,1024)
registersymbol(mem)
createthread(mem)
mem:
mov eax,[01005194]
lea eax,[eax+1]
mov [01005194],eax
push #1000
call sleep
jmp mem
[disable]

{$lua}
writeBytes("mem", 0xc3) --write the ret, autoassemble() would be an option to
sleep(1000)
{$asm}

unregistersymbol(mem)
dealloc(mem)

Why would you do this instead of inc eax?

@Dark Byte the 6.4 solution is the one I was looking for,I agree that using globalalloc is better than using alloc in this case,thanks.

Oops!Thanks for reminding me,forgot about those simple integer instructions.
