CWFI - Cyber Warfare Forum Initiative
There are many great discussions that take place within that group, many projects in the works and a lot of interest being generated all over the place. There is a website, cwfi.us, though still in development but is expected to be launched soon. I would expect that many discussions will be migrated over to the site once ready but I'm sure they'll continue on LinkedIn as well.
There are a lot of opportunities to help out if you feel inclined as well. They'll usually make a post in the discussions asking for volunteers or you can just speak-up and say you want to help
Anyway, just wanted to pass that along as I figured it might be of interest to many people here and I think they'll continue to expand and become pretty important.
Disclaimer: Yes, I joined. Yes, I participate/volunteer. And yes, it's a great group of people
