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.

Cyber Security for PC Gamers

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!).

Broadband Routers

When it comes to digital technology, we have to consider many things.

Availability, Confidentiality, and Integrity are good building blocks for considerations. We can probably split this into two major views to start with:

  • What does a typical consumer care about?
  • What security and privacy considerations could be made?

A typical consumer may be about:

  • Availability
  • Cost
  • WIFI Coverage
  • Performance
  • Ease of Use
  • Ease of Support/Troubleshooting
  • Style/Looks
  • What happens if it breaks?
  • Can I stop my kids messing with it? (Probably not so why bother)

What to do when you think you are being…

Planning is key but you can also respond

Recently I was helping a friend out when they were being targeted by a criminal online. I thought I’d put some notes down to try and help people. This isn’t a “how to” it’s more like thoughts and ideas. It’s UK centric, but probably works in lots of places.

One thing to note, preparation is greater than response, the more prepared you are, the less vulnerable you may be, the more prepared the smaller the attack surface.

You may for a variety of reasons become under heightened threat from an internet perspective. The information on here is not a catch all, a detailed guide to personal (PERSEC) and operational security (OPSEC). Read more “What to do when you think you are being targeted in cyberspace”

Defending against Denial of Service (DoS) Attacks

What is a DoS Attack?

According to NIST, a denial of service (DoS) is:

“The prevention of authorized access to resources or the delaying of time-critical operations. (Time-critical may be milliseconds or it may be hours, depending upon the service provided).”

denial of service (DoS) – Glossary | CSRC (nist.gov)

a distributed denial of service (DDoS) is:

“A denial of service technique that uses numerous hosts to perform the attack.”

Ransomware Defence: Part 2a – Persistence, Privilege Escalation and…

Recap

In Part 1 (Initial Access Defence and Checklist) we looked at ways of hardening your attack surface to defend against initial access. When it comes to ransomware there is a range of elements and variables in the kill chain that need to be successful for the outcomes to be achieved by the criminals. Here we are going to move further into the kill chain to look at further defences. Remember you need to have an “Assume Breach” mindset if you are going to be able to defend against ransomware, that being said, there is a hell of a lot of things you can do for 0 to low investment costs that provide a great ROI. Now some of this is going to be repeated guidance from part 1, that’s ok repetition is good (make sure you are covered from multiple perspectives). Ok let us get to it!

Thoughts on IOCs for Exchange Hafnium/ProxyLogon

Intro

This isn’t a rant, far from it but I’ve been working on this for over a week now and some major questions are sprining to mind with regard to how the IOCs and detection details released may have hindered response efforts. These vulnerabilities were known about since at least December 2020, there were months to get detection intel and scripts/tools ready for people (that’s if you don’t question why did it take so long). So I’ve put some of my thoughts down here on some of the challenges with the IoCs initially released and the detection tools etc. I’ll probably update this later but wanted to publish it before it becomes virtual dust!
