Malware will not be able to do much unless they actually do some system 
calls... They can of course corrupt their own memory if they want to. 
Not that any other process would care...

But it will not even get that far I would suspect, since I doubt VMS 
would even find the image headers digestible. Even if they use the same 
object format (VMS switched to COFF/ELF, didn't they?), a Unix image is 
still not runnable under VMS.
