I think personally:

Viraa knows she's an Innovade
Nobody else knows she's an Innovade
Julia knows SOMETHING is off about Viraa

And Viraa knows every detail about each and every one of you because she's Veda's assistant and probably watches you while you sleep. 

-And on a more serious note when it comes to that, she was the one who went around recruiting the Meisters so it would make sense she knows most everything about them, as she would have been given that information by Veda when she was told to go get them.

As for the Super Soldier program, I'm not sure who would know many details about that. It wouldn't likely be something that is openly talked about, so only people with a personal connection to it, or people he told about it would know. 

And Viraa because she's creepy and knows all your secrets.
