Use Armitage and Cobalt Strike on Amazon’s EC2

July 10, 2012

James Webb has an interesting blog post on how to use Armitage to manage a pen test through Amazon’s Elastic Computing Cloud.

He does a good job articulating the benefits which include using Amazon’s EC2 to test your security from an outside in perspective or using it as a central point for a distributed red team to work from.

He also explains how to obtain authorization for penetration testing activities from Amazon. They do have a process for this and they’re very good about responding to these requests.

You can use Cobalt Strike or Armitage to work with Amazon’s EC2. If you use Cobalt Strike, I recommend using the quick-msf-setup script included with Cobalt Strike to quickly setup your environment. This process is described in the Cobalt Strike Linux Installation Instructions.

Also, when you run the teamserver, make sure you specify the external IP address of the EC2 node and not the private address bound to the network interface on the system. By specifying an external IP address, you’re telling the Metasploit Framework where it should send reverse connections to by default. It’s really important that this IP address is something your target systems can talk to.
