HID Attacks using OMG Cables

Human Interface Devices is the science way of saying (in this case) keyboard! Now that doesn’t sound amazing but then we look at the details. What we are talking about here is a wireless remote controlled programable keyboard emulator disguised as a USB cable or a cable between a real USB keyboard (must be detachable). This provides attack opportunities to both key log and hijack inputs to PC devices covertly and remotely (within WIFI range). Just imagine what you could do with one of these.

Password Auditing with L0phtcrack 7 – A quick intro

If you know me that one of the first things, I recommend organisations do is conduct password audits against active directory on a regular basis. There are a ton of ways to do this and depending upon size of directory and budget you will likely want to do this with more than a CPU however the process remains the same. So, with the news that a new release of L0phtcrack (open source) is online let’s take a look at how we can deploy and start cracking those hashes! This isn’t an end to end guide to cracking with l0phtcrack – but it does show the install process and provide considerations for your cracking adventures. Remember, only do this where you have authorisation. Read more “Password Auditing with L0phtcrack 7 – A quick intro”

Linux 101 for Windows People

Introduction

I come from a heavy Windows background, in fact I started my computer experience on an Amstrad however not long after I was using DOS and then Windows 3.11 for Workgroups. So, I’m a heavy Windows head, I’ve deployed all kinds of services and applications within business environments using common technologies such as:

  • CISCO/DELL/HP Networking switches and routers
  • ISA/TMG/UAG/Checkpoint firewalls
  • Palo Alto Firewalls
  • Microsoft Windows Client (Windows 3.11-Windows 11)
  • Microsoft Windows Server (NT4 – Windows Server 2022)
  • Vmware vSphere/ESXi
  • Random Linux Security appliances and VPN devices

One thing that I’ve noticed in my travels so far is that Linux deployments in enterprise environments in the back office/corp nets are often appliance based or “black boxes”. This creates a bit of a fun scenario whereby some system administrators and operations teams aren’t particularly comfortable with using UNIX/Linus systems. So, I thought I’d try and write some content to show how to do common tasks using the command line interface (CLI). This isn’t designed as an indepth guide, this is really just to try and give people a view of some of the things that you will need to be aware of. This isn’t mean’t to be “academic” or replace manuals and technical docs so it’s brief and to the point (as far as that is possible). Read more “Linux 101 for Windows People”

Creating a honeypot for CVE-2021-41773 (Path Traversal and RCE)

A path traversal vulnerability and exploit just dropped in the wild for a specific version of Apache (Apache/2.4.49). This vulnerability allows an unauthenticated attacker to execute a path traversal attack (and now shown RCE if MOD_CGI is enabled) to read files outside of the virtual directory path bounds. This only affects a single version of Apache, there’s a fair few of these online, however it’s very unlikely all are vulnerable. The vulnerability requires specific permissions to be configured.

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 Art of Cyber

Cyber Security is an intersection of different activities, processes and capabilities. It uses skills from multiple traditional roles. As such the definition of it, often seems to lie in the reader. I did a poll the other day on twitter where ~30% of people thought a scenario I described wasn’t cyber because basically an “IT” person did the activity or they made assumptions that the IT person was told to do it (they were not). This led me to try and describe what Cyber means to me:

Can Cyber Deception be used as a force for…

Scams, Disinformation & Supply Chain Compromise

Now this might come to a shock to some of you but I’m not actually (as my LinkedIn profile currently says) Tony Stark! I know, shocking but it’s true. Why I’m experimenting with this will hopefully be apparent after reading this post (although this isn’t an explanation specifically). What I’m looking at is how deception is used from a range of perspectives from marketing, cybercrime and how we can use deception in a positive way, to actively defend ourselves from the cyber criminals!

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.

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
