Hunting for common Active Directory Domain Services Exploitations

Ok this morning I woke up really really early! I then went on a bit of a KQL thread on twitter, and then IRL work destroyed my plans to play in the lab. However I’m publishing this in its current state [use at own risk etc.] because I think it might help people! So let’s get to it:

These queries can help you identify 3 common active directory attack techniques from logs on a domain controller (this does not rely on ADCS logs etc.)

Leadership

The business ‘value’ of Cyber Investments

A massively common analogy I see in security is the idea that security is like paying for insurance incase something goes wrong. I think this is great if you have 3 seconds only to describe security, but that’s not really how I have conversations with people. A sound bite isn’t reality, and to be honest I personally find that rather meaningless. I also know that many people don’t like or even pay for a range of insurance so when we look at how we try and improve digital security from a whole of society perspective, I think this phrase doesn’t work, it’s too narrow…

A threat actor is inside your perimeter… what routes…

Ok that subject is massive…so this is a bit more of a targeted thought process to consider.

Each network is unique and technology deployments vary. One time I was in a network that was almost entirely Apple MacBooks and a door control panel…. which was ‘fun’.

So this is a general list of some things to consider if you have tech deployed such as:

Active Directory
Printers
SCCM
MSSQL

What are the top Active Directory Security vulnerabilities I…

Ok so here’s the thing, I do NOT like getting pwn3d! I think you probably would rather your organisation does not too!

What I really don’t want to occur is a ransomware event! They suck, they are like a digital bomb going off.

So I’ve knocked up a quick list to get people thinking (these are NOT all the vulnerabilities I networks you should care about.. but they are some that could lead to a ransomware event!)

Threat Analysis Tools

I’ve not blogged in a while, but I wanted to put down a note of some useful tools people can use to help them combat cyber crime.

This isn’t going to be an in depth look at each tool, however I do want to, in the near future, try and do some demos/videos etc. of how to investigate potential/suspected or identified threats. I’ll drop a list of some of the useful tools below and also do a quick demo of investigating an event (from this blog)

Cyber Tips for Normies (without the FUD)

The Cyber Threat landscape in 2023

The digital world is complex and cyber threats appear to be around every corner. What we need to do however is look at how we can enable people and keep them safe from common (realistic) threats that they will almost certainly face (rather than saying everything is a risk!), The intent of this post is to tackle key common threats, risks and vulnerabilities (and countermeasures). It is high level, it is a generic and general, it is not a bespoke tailored guide for each person. It does not cover every single risk scenario someone may face, it simply looks at what I think people may want to focus on (given what I see). (I’m having to caveat this loads to try and stop the tin foil hat loonies making a scene about edge cases I haven’t covered)

No one is responsible for your OWN Cyber Defences…

Introduction

I talk to hundreds or maybe even thousands of people online. I work in the Cyber security industry, I worked previously with central government, local authorities, finance, third sector, healthcare, defence and well most verticals of business. I often see people comment online about how “GCHQ has failed” or some other silly nonsense when it comes to an organisation (not GCHQ) being victim to a cyber incident.

I fear the world has watched a few too many Bond and Bourne films and let’s their imaginations run wild! The true reality of defending cyberspace is frankly vastly different to what I think people believe it is.

Hacking

The Manual Version 2.0

Working in Cyber security can expose you to all kinds of information. I’m an offensive and defensive security architect and occasional (haha that’s daily right!) pew pew slinger (pentester) and I am also a threat intelligence practioner (CTI) (we need The Many Hats Club back!). Which is why sometimes when things appear on the internet I think I decide to take a look.

Introduction

The other day there was a lot of focus on “ATLASOS” a rather oddly branded project, just to be clear:

ATLASOS is NOT AN Operating System (OS) (despite it’s name!)

ATLASOS (at the time of writing) disables basically the majority of Windows Security features including:

Defender
Smart Screen
Windows Update
Spectre/Meltdown Mitigations

Basically, if you can think of “nightmare” in the cyber world, ATLASOS’s security posture is basically that (in my opinion)! That said, it’s cool from a nerd Windows customization/build pov, however based on my initial investigations I would strong recommend NOT using it on a “PRODUCTION” system (or anything that’s connected to the internet!).
