Attacks on WPF applications

Question

What attacks or security vulnerabilities are specific to WPF applications?
To clarify, I'm not asking how to do SQL Injection on WPF apps, or what kind of crypto should I use, or... I'm also not specifically asking about flaws in the Framework, or in WPF itself, rather flaws that might manifest based on improper implementation.
Very specifically, I'm interested on new attacks, or new vectors, that are particular to a client application implemented in WPF. Not specifically XBAP... ClickOnce related issues would be great too.

Answer 1

With WPF, it's easier for someone to steal your GUI. In general, though, it may result in better security because WPF controls do not get windows messaging by default. They use hit testing for dispatching events using routed commands. As far as windows is concerned, it's a game running in that space, not a windows app.
