Reporting an email as phishing in Office 365 with…

Did you ever just ignore or delete a phishing email? I mean that’s great in one sense that you won’t have any negative impact. But if the email did get past the mail security filters, you can report it using the “Mark as phishing” option.

What if as well you wanted to not only enable users to report but also pass the intelligence onto the NCSC Suspicious Email Reporting Service (SERS)? How cool would that be! Well, have no fear people, we are going to show you how easy this stuff is to deploy and configure. Read more “Reporting an email as phishing in Office 365 with NCSC SERS”

The problem with gatekeeping in the cyber security industry

Stark Realities

Imagine having an industry where you can’t be in it without already being an expert in all fields, imagine having to be able to command policy and drive strategy but not having anyone having ever helped you learn how to do this, imagine that if you did all the activities involved with secure service and yet people say you aren’t part of the industry because your job title doesn’t have the word “security” in it and imagine if that you are told you aren’t part of the cyber security industry because you also have to worry about budgets, sales, marketing, new business initiatives, IT services and well anything else!

What would happen if we had this as our cyber security industry principles… well that’s simple?

Cloud Security – 26 Foundational Security Practises and Capabilities…

That is quite the catchy title don’t you agree? Ok so that needs some work and when we think about cloud security, we need to realise that Computing as a Service isn’t a silver bullet.

One Cloud to Rule them all and in the darkness bind them

Ok so the cloud was promised as the saviour of IT and Cyber security but the promise vs the reality. Well, let’s be frank, they don’t really match up. But have no fear – secure cloud design is here (omg cringe)! Ok now we have that out of my system let’s look at some basic cloud security considerations to make when thinking about cloud services.

Checklist

Ok so the world doesn’t work with a checklist however, if you are like me you will want to use lists and aides to jog the little grey cells into action. Let’s think about cloud services and security: Read more “Cloud Security – 26 Foundational Security Practises and Capabilities Checklist”

CVE-2021-22005 – vCenter RCE

Introduction

Protecting admin interfaces is a really good idea, network segmentation however is one thing that many organisations struggle with. Most networks are what we call flat. They may be carved up into VLANs but generally speaking, in a lot of networks if you are “inside” then you have full access across the TCP/IP space.

Now here we are talking about the internal attack surface, so a threat actor would need network routable access which should not be the case for things like vcenter interfaces from the internet, however it appears that’s not really exactly how the world works.

Let’s look in Shodan! Read more “CVE-2021-22005 – vCenter RCE”

Defending against authentication attacks

Ok so my most popular blog on pwndefend is about using Hydra… so I guess that’s all the goodies using it for good things, right? Probably not but it does help people understand the weaknesses of single factor authentication systems without supplementary controls.

So, let’s look at authentication defences, but let’s do this from an attacker perspective! (The opposite of what helps an attacker usually helps defend). Crazy madness right, let’s get to it!

Foundations of Sand

Ok so authentication is a key security control in computer systems. To understand the challenge around authentication and think it’s all a technical problem is to error.

See most modern computer systems require at least two things to authenticate:

  • A Username
  • A Password

Cyber Security Tips – Keeping your digital self, safe!

Not even most of my digital life is in the enterprise security space, whilst this is great if you have access to technology budgets, security specialists and modern business class solutions, this doesn’t really fit into the general populations landscape of technology. I thought I’d take a high-level exploration of what digital security looks for people who aren’t security nerds! This is a bit of an experiment for me as it’s a journey into a world where although some things apply to me (obviously I’m human), some of this from a thinking/blogging point of view aren’t my comfort space. So, let’s see what a world outside of being a nerd look like!

Commons Risks

I’m thinking the risk landscape is still broad however when we think about risks, I reckon a general view model may look at some of the following scenarios:

  • Fraud/Scams
  • Sextortion
  • Phishing
  • Social Media Account Takeover
  • Device Theft
  • Device Loss
  • Equipment Failure/Data Loss
  • Threat from known individuals with physical access
  • Human Error

Cyber Security Design Review

Purpose

To conduct a solution review we need to consider multiple perspectives. Cyber security can be described as (from the NCSC):

“Cyber security’s core function is to protect the devices we all use (smartphones, laptops, tablets and computers), and the services we access – both online and at work – from theft or damage. It’s also about preventing unauthorised access to the vast amounts of personal information we store on these devices, and online.”

Cyber Security is concerned with risks, threats, vulnerabilities, and controls. This really means the breadth and depth of cyber security is vastly wide and terribly deep. Read more “Cyber Security Design Review”

Cyber Security Architecture

I remember (now it was a long time ago) when I worked in a support role and my dream job was being a technical architect, back in the warm and fuzzy days of no host-based firewalls, IPsec being something only MCPs knew about other than the networking team and when cybercrime was a shadow of how it is today.

It wasn’t until I had a few more notches under my belt when I realised that architecture in technology has different viewpoints, not only that but even the industry can’t agree on what things are or are not. That aside the reality is, is that architecture has different domains, specialisms, views, and viewpoints. I often find myself working across a whole range of areas, that is driven largely by specific customer requirements and scenarios (this is why I have a cool lab and lots of kit!)

When we consider a business technology system it has risk and by nature cyber security in that view. To think of this not being the case would be odd because ultimately “business” is the highest abstraction, and let’s think about what makes up a business: Read more “Cyber Security Architecture”

Exposed VMWARE vCenter Servers around the world (CVE-2021-22005)

There’s a new CVE in town but don’t think it’s the only problem you get when you expose administrative interfaces to the wild west of the internet (yeeha or something). Let’s go on a quick exploration of what the world looks like with the help of our friends at Shodan and then let’s see the ramblings of Dan when looking at how benign enumeration and exploration of services can work. Let’s get started looking at the world, a quick face analysis on Shodan with vmware as a product shows a hit or two, what we are going to focus on is vCenter but you know.. you might want to review your attack surfaces so any exposed services (damn people expose some risky stuff!)

Measuring Cyber Defence Success

What does “good” cyber security look like? Sure, we can run a maturity assessment and see what good indicators are and we can create a baseline of our current state to establish where we are and what gaps we have (honestly in real terms this isn’t something to consider you should be doing this!) but how do we measure success in cyber security? Is every success an invisible outcome? Because one question that often comes to mind here is, just because we don’t see something, does that mean everything is ok? In the fast-paced world of cyber security, measuring success isn’t as easy as you would think. I’ll give an example of this, let’s say we don’t monitor, we get breached, but the threat actor just performs crypto mining (let’s say this is on premises) and we never really notice in the grand scheme of the world that our energy consumption costs have increased, if we didn’t know this had occurred, we might think our security is good.
