Metasploit Tidbits

I’ve been working through Metasploit Unleashed in preparation for the PWK course and the ensuing OSCP exam. Looks like I’ll be signing up for that in early July. While you can’t use Metasploit on the OSCP exam, they do teach it in the PWK course itself, and it’s a very powerful tool anyway, so learning it now seemed like a good idea.

I’ve been taking a lot of notes in OneNote as I progress on all things OSCP, but I thought I’d share some of the handier Metasploit tricks that I might find myself using from day to day. Additionally, writing all this out and thinking about it as I do so helps me commit it to memory, so this blog post isn’t an entirely selfless effort šŸ˜‰

Find Hosts on Your Network

The arp_sweep auxiliary module comes in handy to find hosts on your network. In the below example, you select the arp_sweep tool, show its options, then set the RHOSTS variable accordingly for you your network range.

Running the above will return some output that looks something like this:

If you want to be sneaky when you do this (and why would you need to be sneaky on your home network? šŸ˜‰ ) you can spoof the source host (you) and the source MAC address so that it doesn’t look like you have been scanning anything. Typically, you might set this to appear to be coming from your router.

Scan a Host

Metasploit lets you scan hosts that you discover.

You can set THREADS (10) and CONCURRENCY (20) too, to help speed things up without getting too crazy.

You can even use nmap from within Metasploit, and store the results in the database, or import normal nmap results (saved as xml) into the Metasploit database. The advantage of doing this is that you can save your work and results in workspaces in Metasploit. Workspaces let you create projects and keep things organized, which is useful when working on many targets, or with a team.

I will provide some examples of this soon. Stay tuned. For now, here’s what looks like a great reference for this.
