Cyber Leadership – Real Life Incidents over the years!

Introduction

I’ve been around a bit now, I started ‘playing’ with technology very young as a kid! Wolf 3D/Doom era etc (ok even before that but whatever) …

In my professional career I’ve worked with literally hundreds of companies, from mega to small, from household names that sell games consoles through to orgs that sell you yummy food! I’ve worked across loads of industries from government through to manufacturing. I’ve dealt with major incidents for the finance sector, healthcare but also, I’ve been inside a range of networks for some time.

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.)

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

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)

Cisco IOS XE Incident Update

Update 30-10-2023 (fast publish)

This is a fast publish. Based on honeypot data from @SI_FalconTeam we can make some analysis:

  1. The webshell has an authorisation header is 40 characters long. (it is unknown how this was generated)
  2. The user agent in the sample: User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36
  3. The source IP: 192.3.101.11
  4. The stages:
    1. Check for webshell
    • If not in place:
      1. Bypass Authentication (CVE-2023-20198
      )
      1. Create a local LEVEL 15 User AccountSet IP HTTP/HTTPS SERVER and Enable Local Authentication (AAA)Use this account to conduct a device inventory.
    • Inventory the System
    • Kill the created Level 15 account

In the lab we have attacked HTTP and HTTPS and have been able to get AUTH bypass. (thanks @leak_ix)
