Spending New Years Eve on Hack the Box is perhaps a sad story but someone mentioned the Pro Labs and as I looked into what those were about, I thought maybe I should take on a box or two.  Chatterbox is one I hadn't seen so I fired it up to take a look and I haven't come across Achat but the style isn't unfamiliar.  The privilege escalation is a bit of a downer but it's different and there's a lesson to be learned.  I don't really want to spoil part of the box so let's just dive in.  We kick off with Nmap:


    I'm teaching a class this weekend but my time is limited so instead of building something from scratch, I thought I would grab a couple of the more recent Vulnub boxes to see if there's anything I can use instead.  This box is perfect because I've wanted to give a brief primer on Burp and to make the job easier for the pwning, Burp comes in handy which you'll soon discover. 

    Without giving away too much, we kick off with Nmap:


    I'm giving away my book.  I've been sitting on it for a few months and I honestly don't know what to do with it.  It wasn't anything more than an idea, then I started putting words to paper, and the next thing I knew, I had something that resembled a book.  Over the course of the last 10 years or so, I've often thought about writing a book but I'd hammer out a few pages, lose interest, and the idea would fade off.  But not with this one.  I conjured up a vulnerable server and in parallel, I wrote lessons on how to approach it, enumerate it, exploit it, and eventually root it.  It's essentially a vulnerable server with a lesson manual.


    First, let me state that this is not my creation -- if it's not obvious with the author's signature in the menu.  I just happen to stumble across it, I watched the Youtube video, and I wanted to see if there was more to it.  The author, zhacker13, has an excellent start and I hope they continue to build this out further.  I didn't bother to check to see if it could bypass a/v or anything like that because in its current state, it has very limited use.  It can, however, get shells, take screenshots, and upload files.  I didn't bother taking a screenshot because that's part of the video.  I did upload a file and that worked flawlessly.


    First, let me state that I did not create this tool.  Honestly, I don't even know how I stumbled across it because I wasn't even looking for anything of the sort.  I just happened to come across it and it seemed interesting so I decided to fire it up.  It's basically a multi site brute force tool that covers Wordpress, Joomla, Drupal, OpenCart, and Magento.  If the goal is just to brute force the site, this is much easier than Hydra or the specific tools like WPScan.  In advance of running the tools, you need to create a text file which contains the URLs and then you can fire it up as follows:


    The other day, someone asked me why I run my Nmap scans with the flags that I typically use. I think maybe they were asking why I use sT instead of sS.  I don't think sS is any faster and if I choose to use Nmap, I don't care about the noise.  When I DO care, I'm not using Nmap. 

    If you drop onto a Windows machine, right off the bat, what do I want to know?  The OS version, the Fully Qualified Domain Name, and the IP Subnet (/24, /23, /##?).  From there, where is DNS being served.  That's likely to be an important server -- possibly a Domain Controller.  I'd also want to know the location of the mail and web server.  And finally, I'd want to know the names of all of the devices on the network because the names are sometimes telling.
