So I don't know if you guys check out other forums or anything, but I've been reading several things about Warden turning on for D3. We should take heed with what we do and hope for the best!

Blatant warmods are being distributed. Specific details will not be provided as to what each one does for various reasons. As the end-user (read: cheater), all you need to know is that they are there and you should be using a hack with preemptive measures in place to deal with them (such as D3A!). It is the job of the developer to deal with it. Anyone with the need-to-know should already know how to dump and analyze themselves. There is plenty of information floating about. I believe tracing back from FIC or [md5].mod reference and obtaining RC4 decryption key on warden loading is still the common convention, but I don't know much direct information regarding D3's implementation specifically.
