Tool Sharpening

As honest Abe Lincoln said, “Give me six hours to chop down a tree and I will spend the first four sharpening the axe.”

For the last six months, I have been playing the part ofย Hey Blinkin, getting the tools in my toolbox sharpened, honed, configured, and ready as I am inches away from starting the PWK/OSCP course. As soon as some paperwork clears, I’ll be signing up, hopefully to start in mid-July. You may have seen me posting things I’ve learned so far here on my blog. I intend to keep it up, as finding other OSCP adventurer blogs, tips, and tools along my journey has been invaluable. I hope to pay it forward here.

That said, here are a few very sharp tools I’ve come to love (as recently as this evening):

iTerm 2 – http://iterm2.com/ – a better Terminal app for Mac. Highly configurable, integrative, and versatile. Not exactly a pentesting tool, but something anyone doing command line work on a Mac should check out.

Sn1per –ย https://github.com/1N3/Sn1per – a super-thorough and invasive reconnaissance tool. It is very noisy and not recommended for actual pentesting, but it is great for working on CTF and Vulnhub VMs.

OSINT Framework –ย http://osintframework.com/ – a hefty, well-organized set of free tools for gathering all kinds of information. Originally geared towards security, it includes a lot of other fields as well. Follow it on GitHub here.

Microsoft Windows has Free Virtual Machines

Wish I had know about these earlier. Microsoft offers free Windows virtual machines for VirtualBox, VMWare, and others. You can choose from Windows 7, Windows 8, or Windows 10 (a few different flavors of each). They last 90 days before expiring, but you can snapshot them right after you install them to make it easy to reset that 90 days by rolling back to the snapshot.

Officially, these are for testing out the Edge browser, but you can also use them for whatever else ๐Ÿ˜‰

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 ๐Ÿ˜‰

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? ๐Ÿ˜‰ ) 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.
