Enable Number Matching in Azure MFA

Introduction

MFA was the “silver bullet” but friction and security kind of go hand in hand, the idea of a push notification and simple “authorise” is great in theory, but in practise it is vulnerable to brute force and human error. In this post we are going to check out enabling number matching authentication in Azure.

This is just one configuration option, as you can see there are loads of options for methods and specific configurations. Bear in mind the pros and cons for each one, for example SMS based 2FA can be vulnerability to SIM swapping attacks. I’m going to focus on Number Matching in Authenticator for this post: Read more “Enable Number Matching in Azure MFA”

When running Nessus is a good thing!

Oh that’s “just a Nessus scan” or that’s not a real pen test etc. is something that if you are in the infosec/cyber world for a few minutes you will probably hear.

It’s honestly a bit odd, some sort of way of diminishing something because a tool was used, which doesn’t really make a whole lot of sense given most activity involves using something that already exists (sure there are fields and scenarios where this isn’t true but I’m generalising).

So why are we as an industry obsessed with tools and obsessed with berating people for using them? It’s all rather odd.

It perhaps ties in with this Cyber Myth about penetration testing being the tool that’s good and useful in every scenario… I hate to break it to people, but it’s not the principles of security and it certainly isn’t the best/most appropriate “tool” in every scenario.

Supplier Assurance Tools

Do they replace the need for OSINT and Supplier engagement?

I’ve been conducting sales and assurance-based activities for some while (I’m not counting it will make me feel old!) and I have started looked at a range of supplier management tools which leverage tool-based OSINT, attack surface mapping and manual data inputs and I have to say this:

Vulnerability Management Concerns by Role Type

Have you ever thought about what kind of data/intelligence you may need with regards to vulnerability management? It tends to vary at levels of abstraction based on the audiance, but don’t think the person doing the patching may not be considernig upwards or that someone in a C level position won’t care about the zeros and ones (life doesn’t work that way!)

Anyway I was talking to a friend and came up with these so thought I’d share them with the world. Have I done a decent job? can you think of others? How do you measure and report? What are your concerns?

Let’s take a look at what I came up with (this wasn’t a very long time in the making 😉 )

UK NCSC Active Cyber Defence (ACD)

Defending a single server is often far more complex than people apreciate, defending a single organisation is significantly harder than a single server, defending a country… a much more complex challenge than I think people actually realise.

What is ACD?

According to the NCSC:

The aim of ACD is to “Protect the majority of people in the UK from the majority of the harm caused by the majority of the cyber attacks the majority of the time.” We do this through a wide range of mechanisms, which at their core have the ability to provide protection at scale. 

ACD is intended to tackle the high-volume commodity attacks that affect people’s everyday lives, rather than the highly sophisticated and targeted attacks, which NCSC deal with in other ways.

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.
