Setting up infrastructure for a Red Team engagement can be time consuming and difficult. Jeff Dimmock and Steve Borosh have done a lot of work to make this process easier and more transparent. They gave a great presentation. that went over the fundamentals of setting up good Red Team nfrastructure. As part of this effort they released a wiki.
One of the most interesting bits of tradecraft released in this talk and on Jeff's blog is their very creative use of apache2’s mod_rewrite functionality. Mod_Rewrite is very powerful for a few reasons:
- It can be used to hide the true location of your Teamserver
- It can be used to evade detection from Incident Response
- It can be used to redirect mobile users away from a payload to a spoofed login portal, to capture credentials
- It can be used to block specific ip addresses from your teamserver, to aid in IR evasion
- It can be used to only allow your Malleable C2 traffic to the Teamserver
In a Red Team engagement, there are often multiple teamservers, and multiple redirectors in front of each teamserver. In the event that a defender identifies and blocks one of the redirectors, they should be easy to recreate. However, manually setting up mod_rewrite ruleset for each redirector can be very difficult and time consuming. To make this easier, I automated some of the setup process and tried to include as much functionality as possible.
