OMG The Cyber SKY is falling down!

Ok a bit dramatic, but that’s often what you might feel if you spend lots of time in the vulnerability space (which if you work in cyber security.. you probably do!). We often hear about the NEXT: STUXNET, HEARTBLEED, WANNACRY/ETERNAL BLUE, LOG4J etc. but actually when it comes to it… the number of times we have word endangering unauthenticated remote code execution that is a danger to global society is far less than when we have other vulnerabilities. It’s the exception not the rule.

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

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.

Adopting an Attacker Mindset to Defend Healthcare

This post started as a reply to a great topic on LinkedIn, but I hit the character limit so now it’s a blog post!

Years ago I simulated attacks (authorized obviously for the people that have wild imaginations) on a customer which included a physical attack where I walked into a healthcare organization, armed with a suit a smile (and a USB key) I needed to gain access and attempt to move laterally and escalate privileges.

Active Directory Security Cheat Sheet

Ok you need to do some AD Security Auditing or Security Testing/Exploitation, great. Let’s look at some of the common misconfigurations and some tools to help you, a list of things will obviously not be the answer, you will need a method and process to go through from recon/enumeration through to exploitation and impact (effects), but that’s what google is for (and CTFs/Labs)! This post is just me jotting down some notes, hopefully they help defenders think about improving their posture.
