Vivi Posted October 27, 2015 Posted October 27, 2015 Hey dear community,i write alot of programs that i sell.i coded a sucessfull license system but sadly i have no protection against memory dumps. i already tried playing with "memory.au3" but failed at it. Reveal hidden contents #include <WinAPI.au3> #include <Memory.au3> #include <NoMadMemory.au3> $Mem_Open = _MemoryOpen(@AutoItPID) $baseAddress = _WinAPI_GetModuleHandle(0) _MemVirtualAlloc($Mem_Open, BinaryLen($Mem_Open), $MEM_COMMIT, $PAGE_GUARD) anyone has a idea how i can call use page guard ? Thanks
Mobius Posted October 27, 2015 Posted October 27, 2015 Many products have tried but all fail in this regard, particularly in situations where someone knows what they are doing.Sorry Vivi but that's just the way of it.Vlad

Mobius Posted October 27, 2015 Posted October 27, 2015 Who's talking about decompilation?(despite you bold and incorrect assumption regarding this long term)We (or rather you) are talking about memory, the weakpoint of every application to date.Am I saying implementing page guard is Impossible? No not really, and hopefully someone will at least help you do this much to put you in a false sense of security mindset short term so you can continue developing your content without worrying where the holy grail has been stashed.

JohnOne Posted October 27, 2015 Posted October 27, 2015 That is not the only decompiler, and it will not protect a script against decompilation.If it did, you would not be here looking for a solution.Plenty get the script from memory at runtime. you cannot stop that.

Mobius Posted October 27, 2015 Posted October 27, 2015 (edited) @Vivi please remove the name of the decompiler in post 6 and use something like "memory based or focused decompiler". As JohnOne has stated it isn't the only one these days so there is no real need to reference any single one by name. Edited October 27, 2015 by Mobius
