KreiosC2 in the Press
Version 2 was launched at Defcon 2009 in a presentation by Tom Eston and Kevin Johnson called "Social Zombies: Your Friends Want to Eat Your Brains". Here is a video of their talk.
Version 1 was featured in Tom's Notacon presentation The Rise of the Autobots where he discussed the topic of creating and using bots with social media sites to either automate their use or use the sites themselves to aid other enterprises.
We also made it into an article on Dark Reading in an article on the new ways handlers are communicating with their bots.
