There was a discussion about it on Reddit netsec a few days ago: http://www.reddit.com/r/netsec/comments/1ozoiy/darpas_cyber_...
Finally, the program manager running it, Mike Walker, is going to be giving one of his first public talks about the Cyber Grand Challenge at THREADS in NYC on Thursday, November 14th: http://threads.isis.poly.edu

Once they've automated defense, how long until someone automates offense... and then how long until everyone is caught in the middle of a cyber arms race?
If a computer system is designed to defend itself against attackers, where does that path lead? Before this project, I've laughed off the Skynet conspiracy theories, but given the recent revelations about the amount of trust we can put in U.S. government agencies, and a project of this nature in the hands of a U.S. military agency, this should be raising huge red flags in people's minds.
