I'm working on implementing Adobe Content Server to deliver locally stored ebooks to users in my library. Many of the books that we have come with DRM restrictions such as online reading only, single user, etc. Anyway, we've been doing security testing and found quite a few ACS DRM crackers online (like epubor) that work quite well and are very simple to use, which makes us wonder if ACS is even worth it. Does Adobe keep up with these and actively patch against them?
did you get any security patch from adobe againest ACS DRM crackers.
