So in Artmoney i recognized int, string, double, and float valules... programatically they can only be assigned as the correct type but what about externally?

So with Artmoney or related programs could you enter a different value type (without having it convert the value to the correct type)?

Possible? -> Complications?

_{I don't have artmoney pro ofc}

I'm kinda confused as to what you are asking. Artmoney can read a process in RAM, and edit values of data. I don't see why you can't edit a bit of data to contain an incorrect data type, maybe Artmoney checks the entry fields and ensures only correct types are sent in, I don't know.

For example a character value would require 8 bits, so you could modify those 8 bits however you want, but whatever program is reading that character value will read the 8 bits as a character representation.

Could you enter 4 bytes instead of 2 bytes?
Of course. You can change one byte at a time, or 32 bytes at a time. If you use the memory editor you don't have to convert the number to decimal either.

If the program uses the value as 2 bytes then the extra data wont do anything (unless the next memory location was read as a different variable, in which case undesired results may occur).

Does that basically mean you can abuse a program like you could abuse EUDs in SC? Of course it would be much different, but same basic concept, no?

Yes, using artmoney or some memory editor is exactly like using EUDs, except that it's built into the map itself. Using artmoney, you can give your units shields, make them really really fast, etc...

@bioatk yeah, that's called a buffer overflow. You can exploit bad code to access other parts of a user's operating system using it, which is ostensibly why blizzard patched EUD actions. If any program which uses the internet is susceptible to buffer overflows, it then means the user's computer is open to a cracker, which is why good code is so important.
