Probably not. Plenty of toxic proteins have a published structure and are quite easy to grow in a lab (i.e. an undergraduate could do it). The problem with using proteins to do evil things is that they tend to have short half-lives, aren't easily transmissible, etc. There are some exceptions to this, of course, but there's far more practical ways to do evil things.
