They do know how to get the keys, yes, but, it's not automated and requires utilizing an inherant flaw in software players. So, to make this approach work you need one of the following:
-Slysoft would need to either have a predefined list of keys, which in my opinion is an unworkable approach
-or would have to figure out a way to automate the memory scanning approach which would require you to have a specific software player that they know about and can work with which is also unworkable IMO
I've been wrong before, so, it's possible I'm wrong here.
