I haven’t had tea but I was thinking about the MAC i was remoting into and I suddenly thought.. I wonder how to crack the hashes from a MAC. Surely it’s just cat /etc/passwd and cat /etc/shadow and then unshadow and run hashcat right?
WRONG!
The hashes for local users are stored here:

When you gain access to a target node you will want to explore, the exact method you use to do this will depend upon operational security considerations, time constraints and style. You will be looking for a range of elements to support progressing an objective.
It should be noted that the objective may NOT require elevation. You may be trying to obtain data and access might already be possible using the context you have assumed.
You also may need to move from a www-data user to a named user account or get to root level of access. If so there’s a range of questions we should be asking ourselves:

TLDR: If you have been hunting for privescs before you will know it’s normally not a fast task, you will have a shed ton of data to look at. Sure WINPEAS is good but it’s not a silver bullet.
Here is a really small script which focuses on system administration files/scripts, scheduled tasks and scheduled task history to help you hunt for weaknesses:

Ok imagine this, you have got access to a file server and behold you find an unsecured, unencrypted backup of a domain controller (this isn’t made up I find these in networks sometimes!) and you yoink the NTDS.dit (or maybe it’s just a workstation SAM/SYSTEM file), you extract the hashes but now what, you need to crack those bad boys!
Check out the MS docs on how NT or LM Hashes are computed(hashed)! – (thanks @ANeilan for spotting my mistake!)

If you know me that one of the first things, I recommend organisations do is conduct password audits against active directory on a regular basis. There are a ton of ways to do this and depending upon size of directory and budget you will likely want to do this with more than a CPU however the process remains the same. So, with the news that a new release of L0phtcrack (open source) is online let’s take a look at how we can deploy and start cracking those hashes! This isn’t an end to end guide to cracking with l0phtcrack – but it does show the install process and provide considerations for your cracking adventures. Remember, only do this where you have authorisation. Read more “Password Auditing with L0phtcrack 7 – A quick intro”
I created a PDF notebook a while ago when I decided on a whim to to the Pentest+. I have quite a few people ask me about getting into cyber security and well, you know when I was younger this stuff was just called IT mainly (IT + Infosec) so I thought let’s go test out the Pentest+. I did the course and exam in a week (whilst writing the notebook) (don’t think that’s a good idea but my objectives were more to make sure if I think it’s any good or not). Pleased to say I thought the course was good (I used pluralsight at 1.x speed) and the exam was fun (for an exam).
Hopefully this helps people explore the some of the world of offensive security and appsec. Read more “mRr3b00ts Pentest Plus Study Notebook”
Now this might come to a shock to some of you but I’m not actually (as my LinkedIn profile currently says) Tony Stark! I know, shocking but it’s true. Why I’m experimenting with this will hopefully be apparent after reading this post (although this isn’t an explanation specifically). What I’m looking at is how deception is used from a range of perspectives from marketing, cybercrime and how we can use deception in a positive way, to actively defend ourselves from the cyber criminals!

Protecting admin interfaces is a really good idea, network segmentation however is one thing that many organisations struggle with. Most networks are what we call flat. They may be carved up into VLANs but generally speaking, in a lot of networks if you are “inside” then you have full access across the TCP/IP space.
Now here we are talking about the internal attack surface, so a threat actor would need network routable access which should not be the case for things like vcenter interfaces from the internet, however it appears that’s not really exactly how the world works.
Let’s look in Shodan! Read more “CVE-2021-22005 – vCenter RCE”
There’s a new CVE in town but don’t think it’s the only problem you get when you expose administrative interfaces to the wild west of the internet (yeeha or something). Let’s go on a quick exploration of what the world looks like with the help of our friends at Shodan and then let’s see the ramblings of Dan when looking at how benign enumeration and exploration of services can work. Let’s get started looking at the world, a quick face analysis on Shodan with vmware as a product shows a hit or two, what we are going to focus on is vCenter but you know.. you might want to review your attack surfaces so any exposed services (damn people expose some risky stuff!)

Ok today we are going to look at deploying Kali 2013.3. The install process for this is fairly standard and familiar from previous version but for those new to this world, it seems like a good place to start.
Boot from the ISO
