Could Metatrader steal data?

Given that Metatrader knows exactly where your expert advisor script or the DLL file is on the disk, then the software could very easily open it, maybe serialize it and then send to one of their servers. Actually MT for sure loads the EA scripts in the app memory, while for DLL I think that it communicates via OS mechanisms(I'm not very sure about this). Eitherway, the idea is that yes, it is possible.
