I'd be surprised if Helena didn't know, and if she wasn't Kathy's agent in place. She covered for him a few too many times in those first 8 issues, and didn't report him for any transgressions, even the ones where the innocent explanation might be that he hadn't fully settled in yet.
And it was always just a little too pat that when Minos detected transmissions taking place, she found Lotti's cameras... but it was Dick's room that we saw her investigating. In all likelihood she'd known about Lotti's games for a while and had been saving them up for a useful opportunity, and she went through Dick's room just to check that he hadn't left any incriminating evidence behind him.
Minos clearly didn't know though. And I'd tend to agree that Tiger doesn't either, and that it's likely to become a point of conflict if and when he does find out.
