Cortana: real-time collaborative hacking… with botsAugust 3, 2012
At BSides Las Vegas, I talked about Force Multipliers for Red Team Operations. In this talk, I shared several stories about how my evil bots stole passwords, instantly installed back doors, and generally wreaked havoc on college students defending (sometimes) unpatched systems. Today, I’d like to introduce you to the technology behind this havoc: Cortana.
You may know Armitage: a red team collaboration tool built on the Metasploit Framework. Cobalt Strike is Armitage’s commercial big brother. Both packages include a team server. Through this team server, multiple hackers may control compromised hosts and launch attacks through one instance of the Metasploit Framework.
Inspired by my days on IRC in the 1990s, I wondered what would happen if I added bots to this collaborative hacking setup. This wondering (and a DARPA contract) led to Cortana, a scripting language for Armitage and Cobalt Strike.
What can I do?
Using Cortana, you may develop stand-alone bots that join your red team. Cortana bots scan hosts, launch exploits, and work on compromised hosts without stepping on each other or getting in the way of their human teammates. Think of this system as
Google Wave Apache Wave for hacking.
Cortana scripts may also extend the Armitage and Cobalt Strike clients with new features. Cortana scripts can expose hidden Metasploit features, integrate third-party tools and agents, or control other Cortana bots.
If you’ve ever written scripts for an IRC client such as mIRC, irssi, BitchX, or even jIRCii–you’ll find yourself right at home with Cortana. The best place to start is the Cortana Tutorial. This document is a 55-page tutorial, reference, and collection of examples.
If you’d like to get involved writing Cortana scripts, head over to the Cortana Scripts Github repository. Fork the repository and start hacking away. Several example scripts are available, right now, for your copying and pasting pleasure.
If you have questions, join the Cortana Hackers Mailing list. Send a blank message to email@example.com and you will be subscribed. You may send a message to firstname.lastname@example.org to unsubscribe from the list.
If you’d like to connect on IRC with other Cortana hackers, join #armitage on irc.freenode.net.
The latest trial of Cobalt Strike has it too.
I first announced Cortana at DEFCON 20. The slides from this presentation are available as well.
