Password Auditing with L0phtcrack 7 – A quick intro

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”


mRr3b00ts Pentest Plus Study Notebook

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”


Can Cyber Deception be used as a force for…

Scams, Disinformation & Supply Chain Compromise

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!

CVE-2021-22005 – vCenter RCE


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”


Exposed VMWARE vCenter Servers around the world (CVE-2021-22005)

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!)

Installing Kali 2021.3

Hax fun with the Dragon distro

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.

Install Procedure (Virtual Machine)

Boot from the ISO

Graphical user interface, application

Vulnerability Management – Actually doing it!

Vulnerability Management, Assessments and Vulnerability scanning is sometimes treated a with distain in the Offensive security community, I personally don’t understand that. Vulnerability management is key to inputting into security strategy, architecture, and operations. It’s coupled heavily to many other processes such as:

  • Asset Management
  • Risk Management
  • Patch Management
  • Change & Release Management
  • Security Testing
  • Security Monitoring

Before we start deploying let’s think about some areas for consideration when performing vulnerability scans:

  • Scope
    • Asset/Hosts
      • IP Ranges
      • Hostnames
    • Connectivity
      • VPNs
      • LAN/WAN
    • Device Types and Configuration
      • Domain
      • Workgroup
      • Appliance
      • ICS
      • Printers
      • Network Equipment
    • Unauthenticated View
    • Authenticated View
      • Auth Types
      • Protocols
    • Scheduling
    • Authority to execute
  • Impact
    • Performance
    • Availability
    • Confidentiality
  • Objectives and Outcomes
  • Reporting
    • Information Flow
    • Report Storage and Confidentiality

How to Identify Hashes

Some hashes are obvious but even then, it’s a good job to check. There are a few ways to check a hash outside of manual validation.

Using the Hashcat example list:

Graphical user interface, text, application, email

Description automatically generated

Using hash-identifier:

Using cyberchef Analyse hash:

Background pattern

Description automatically generated with low confidence

Using hash-id:

Using HashTag:

As you can see there are range of tools available to you, and remember if you want to keep the hashes to yourself you can download Cyberchef and run it locally!
