Advanced Rootkit Exploit – Demonstrated
This is mainly post-expoitation demonstration, that first starts with a walk-through of exploiting a windows machine. Next, we walk through getting a copy of the web server’s home page and then modify it with an iframe that points to an exploit server. Anybody that browses to the victim webpage now gets owned.
Once it’s set up, we move to post exploitation.
This is a great example of some of the hands-on labs you will do in the InfoSec Institute Advanced Ethical Hacking class.
After we own the page and make it a browse by attack page, we then exploit the server again, create an .ini file for a rootkit to make the rootkit hide the infected page from every windows service (including windows itself mostly), except for the w3wp service (which actually serves the page out). The kit also makes netcat listen on port 100, then hides netcat, and even HIDES the open port 100! So taskmgr, netstat, Anti-virus et al are useless. You wont find anything. We then prove that the port is open by telneting to it and gaining yet another shell. Then we go back to the victim (playing the victim) run netstat -an to see all open ports, and show that 100 doesn’t show up.
Then we go to task manager, and tasklist to see there’s no netcat running. And lastly, but most importantly, I show that there is no way to actually see the infected page unless you browse to the actual web page. You cannot see it from the victim side by doing any command line stuff nor by looking at it through windows explorer. Traditional live forensics will NOT help you…we need to do some rootkit forensics, which we do in-depth on this exact case coming up next (will be linked here when live tomorrow).
