Deploy a mini Pentester Lab with Docker

I build VM labs. Lots of them, but I tend to go full machines. I was checking out the new TCM web app course the other day (honestly i’ll write a review if I get time to finish it!) and it’s built around using docker for DVWA and OWASP JUICE SHOP so I figured I should write a quick blog about how to deploy these so people can get started learning in minutes.

Now here we have:

  • DVWA
  • JUICESHOP
  • METASPLOITABLE

but you don’t have to stop there, i’m sure there’s others you can use as well!

This isn’t an exhaustive guide, but it will get the docker instances up and running.

Testing Risky Egress Ports

Have you ever wanted to run a quick test of egress ports from userland from a windows machine?

Well worry not, I didn’t even have to write anything, the nice people at Black Hills security have done it for us. However I did decide that there’s a few other things we might want to do, so I made a quick modification, now we have colours, randomisation and some sleeps.

Installing Nessus Pro on Kali Linux

You can deploy Nessus in a range of ways, from direct install through to using a cloud-based deployment or virtual appliance.

A common reason for deploying on Kali or other distro rather than using the virtual appliance is for mobility, ease of use but also you might want to VPN or proxy traffic.

The install process is simple, log into your account on tenable community portal and download the relevant installation package.

CVE-2022-26134 – Confluence Zero Day RCE

We are seeing active exploitation in the wild: MIRAI deployment, coinminer deployments etc.

THIS DOES SHOW IN THE ACCESS LOGS! The comment about “what isn’t in the logs” is about POST request BODY not showing in them, not that nothing is logged

Cyber Essentials – Out of the Box

New machines means it’s easy right?

Ok, another post on cyber essentials! I talk about this quite a lot (mainly driven by procurement requirements rather than orgs expressing a deep desire to “have better security” (which is a shame)) however, I want to show people what the real world is like and that meeting cyber essentials is a good thing, but also to look at real world challenges of meeting the standards. In this post we look at some thought provoking questions, then we look at an out of the box Windows and MAC device to see if they meet the standard!

Adding a removing the mark of the web via…

A quick post becuase this is useful for security control testing:

If you want to enable MOTW (mark of the web) on a file you can run the following PowerShell cmdlet:

Set-Content -Path '.\safe3.rtf' -Stream Zone.Identifier -Value '[ZoneTransfer]','ZoneId=3'

This will set the alterate data stream (ADS) Zone.Identifier value to ZoneID=3 (Internet Zone)

You can unblock this with

The Director of GCHQ speaks at CyberUK 2022

Sir Jeremy Fleming was speaking at CyberUK, the UK’s flagship cyber security conference this week.

The full presentation is here but I’ve picked out some key highlights.

“Of course, we can count ourselves lucky compared to those caught up in wars, but we are also seeing a heightened cyber risk. Cyber criminals are consistently evolving their tactics; the lines are blurring with hostile state activity and ransomware remains a real threat.”

“Cyber clearly matters to everyone.”

“At the global level, the UK has developed as a cyber power. Alongside the more traditional forms of diplomacy and statecraft, cyber now plays a vital role in our national security and prosperity.”

Cyber Events vs Incident vs Attack

Cyber Events

Yesterday I was asked about “attack volumes” I see in the PwnDefend HoneyNet and it reminded me about what people think an “ATTACK” is and therefore spring my brain into thinking about how we as an industry communicate. Far too often I see “number of ATTACKS” being used my marketing/sales etc. where the numbers are simply ridiculous and not reflective of how offensive cyber operations actually work.

Let’s look at some examples:
