Common Windows Services

Exploitation of common windows services is an important area of knowledge for both offense and defence.

Server Message Block (SMB)
Remote Desktop Protocol (RDP)
Windows Management Instrumentation (WMI)
Windows Remote Management (WinRM)
File Transfer Protocol (FTP)

Other common technology platforms in the Windows Stack Include

Active Directory Domain Services (ADDS)
Active Directory Certificate Services (ADCS)
Internet Information Services (IIS)
Microsoft SQL Server (MSSQL)

For now I’m just going to look at a few of the common protocols and vectors.

Creating a tracker and dashboard for Cyber Essentials

I was talking to a friend about a requirement to “measure” cyber essentials compliance. Now if you know a thing or two about standards and applying standards to complex technology environments you might come up with:

Can’t we just script a checker?
Don’t we have all the audit data in the *checks notes* 1000 inventory systems we have?

Well sure, you could write a massive set of rules which ignore any context and try and cater for a huge number of different scenarios. You could use the Q&A approach as well (which is how the standard workbook works anyway so that already exists). But let’s say you are an IT manager, and you want to KNOW how your environment stacks up!

The question is simple, it’s easy to ask, look:

“How compliant are we against Cyber Essentials?”

Testing Risky Egress Ports

Have you ever wanted to run a quick test of egress ports from userland from a windows machine?

Well worry not, I didn’t even have to write anything, the nice people at Black Hills security have done it for us. However I did decide that there’s a few other things we might want to do, so I made a quick modification, now we have colours, randomisation and some sleeps.

If I was looking for entry level jobs in…

Sales darling, it’s all about sales. It’s a harsh but true part of the world where you need to be able to sell. I’m not talking about business to business or hunters, farmers etc. I’m talking about being able to sell to someone that you are the right person to help them and their organisation.

Now this isn’t easy in the middle or tail end of a career let alone when you are starting off. But let’s for a minute role play and look at what I would do if I was new to the cyber world and was looking for a role?

This isn’t meant as a guide, it’s off the back of a convo I’ve just had with someone struggling in the job-hunting space. So, it’s a rough brain dump from me. The key thing I would say is: Read more “If I was looking for entry level jobs in cyber security – what would I do?” →

Reporting an email as phishing in Office 365 with…

Did you ever just ignore or delete a phishing email? I mean that’s great in one sense that you won’t have any negative impact. But if the email did get past the mail security filters, you can report it using the “Mark as phishing” option.

What if as well you wanted to not only enable users to report but also pass the intelligence onto the NCSC Suspicious Email Reporting Service (SERS)? How cool would that be! Well, have no fear people, we are going to show you how easy this stuff is to deploy and configure. Read more “Reporting an email as phishing in Office 365 with NCSC SERS” →

The problem with gatekeeping in the cyber security industry

Stark Realities

Imagine having an industry where you can’t be in it without already being an expert in all fields, imagine having to be able to command policy and drive strategy but not having anyone having ever helped you learn how to do this, imagine that if you did all the activities involved with secure service and yet people say you aren’t part of the industry because your job title doesn’t have the word “security” in it and imagine if that you are told you aren’t part of the cyber security industry because you also have to worry about budgets, sales, marketing, new business initiatives, IT services and well anything else!

What would happen if we had this as our cyber security industry principles… well that’s simple?

My MSBlaster Story

We looked after about 3-3500 endpoint devices. We were running Windows servers/clients and we leveraged technologies such as:

Dameware Tools
Remote Desktop Protocol
GFI LanGuard
RCP/SMB/WMI
McAfee Antivirus

Cyber Security Assesments for Normal People

Ok so you might think I’m mad with the title but bear with me!

So, the world is in an interesting place, we’ve got a pandemic, we’ve got prolific cyber crime and we have all kinds of different views on how we should tackle this problem.

Now I love a framework and there’s ton’s of them. But the truth is they are complex, detailed, nuanced and generally require a level of nerd that a lot of organistaions do not have.

In 2020 during the pandemic I decided to try and write something to simplify this position, whilst I didn’t want to be too narrow, I wanted to try and capture the breadth of cyber security that is relevent to the general purpose organistaion. I came up with a set of 140 questions which I believe are a good take on things to consider and ask when conducting a security review at a high level. (yes 140 questions is a high level view, this stuff is complex as hell at the detailed end of things, and the devil is in the detail).

Cyber Defence is Hard

Introduction

If you read a book about management theory or specifically cyber security management you will find lots of frameworks, methods, formulas, models etc. None of them really let you know how insanely hard it can be to defend a moving target where regardless of how many controls you have, all it takes it someone doing something which may seem bonkers to you but perfectly reasonable for them. Their objective is to do business in an efficient manner, your objective is to protect the business in an efficient manner. Fundamentally these two things are not at odds, but there are a lot of human factors that come into play on top of some serious technical challenges. Read more “Cyber Defence is Hard” →
