The three biggest content management systems (CMS) are:

  • WordPress which controls over 50% of the market share.
  • Joomla which controls a little over 6% of the market share.
  • Drupal which controls a little under 5% of the market share.

Personally, we've been hosting, developing, and managing WordPress sites for over 5 years.  Joomla is the first CMS we've used and we've been hosting, developing, and managing it for over 10 years.  But when it comes to Drupal, we have very little experience other than exploiting it and almost exclusively with Drupalgeddon in the last few years.  Aside from that, we haven't seen a need to learn yet another content management system for the purpose of using it for its intended design.

I'm a big fan of people who take time out of their day to help others in the community, especially with something as time consuming as building a vulnerable server.  So when I state that I don't really like the capture the flag style boxes, it's nothing against the maker and it's just a personal preference.  I'm sure it's enhancing my critical thinking skills and I should be happy with that but sometimes these challenges frustrate me. 

FristiLeaks is one of those boxes that tested my patience.  My frustration came out at the end when I saw how I was supposed to conquer this box and instead I went for the kernel exploit.  Granted the kernel exploit is the fastest way to root so there's that but the author had intended for it to be more of a game.  

Anyway, in protest:

I spent the weekend at a red teaming class -- when I returned, I jumped up on Vulnhub and I found a new batch of boxes waiting to be exploited.  Needless to say, it's like winning twice in the same week. 

I'm so appreciative of people who are willing to spend the time building these boxes because it allows others in the community to work on their skills -- for free.  Needless to say, I've downloaded a number of boxes from this recent batch and while perusing the list, I randomly picked Web Developer as my first to attack.  

If this box is any indication of how the rest will go, I will be very pleased because the author tossed in a couple of new avenues that I've yet to see.  While not particularly hard, if you have some knowledge with these avenues, this box still makes you think and jump through some hoops.  

Bottom line, this one was clever and a lot of fun!

As I like to do in my spare time, I work on vulnerable machines for my continuing education.  The vuln box W1R3S: 1.0.1 crossed my path and I uncovered a previously seen entry point with a new twist.  Aside from this new twist, if you've come in through this door, you know how to get through, you just have to work it a little more than the previous times you've seen it.  I'm going to leave it at that because this isn't a walk-through and I'm probably spoiling too much already.  

While enumerating the box, I saw what I believe to be an intentional rabbit hole and it seemed like a great way to play around with Burp's Invisible Proxy.  

Starting from the beginning, we kick off with an Nmap scan:

Microsoft has given us the ability to report messages as Junk or Phishing to help improve their accuracy.  I would love to customize what they've given us to send messages elsewhere but Microsoft didn't provide us with that option.  

The problem is that not all messages are black & white obvious and users might not be able to determine the legitimacy of a message.  I would love a single click button that would forward suspicious email to our team where we can give it a hard look.  Now thinking about that scenario for a second -- if a user forwards spam, it could get flagged on our end as spam.  

Spoiler alert:  We're going to create such a button.  In the design, we're going to forward the message to a specific address that we can whitelist to prevent the forwarded message from getting trapped on our end.  In addition, we're going to change the subject to one that allows for easy identification.

I've seen quite a few good phishing emails and, generally speaking, the object is to get you to open or click on something.  Often times, clients will forward messages to me and ask me for my opinion before opening and / or clicking.  I got one of those emails and I moved it over to the burner machine for investigation.  Maybe you've seen this particular approach but it's a new one for me as far as seeing it in the wild.  It looks like an attachment and it's from a known sender domain.  

Right off the bat, it seems suspicious because it got flagged on my end before it even got to me.
