Kubernetes is getting popular by the day, and is probably one of the hottest buzzwords of 2018.

With names like eBay, Goldman Sachs, Huawei, ING, SAP, and many others listed as corporate users, it is surely a technology which has got a consolidated place in our industry.

At the same time, Kubernetes got the infamous nomea of being hard to understand. Mostly due to rumors, but some other times it has been proven to be easy to get wrong, like experienced by the Monzo team a few months back:

I still remember the sense of confusion when I decided I wanted to get a better understanding of Kubernetes, as I felt like I didn’t know where to start, or what to tackle first.

In this post I will try to demystify the perception by which Kubernetes is believed to be too hard to even get started, by walking through the journey I undertook to get the basics first, and later to focus on the security aspects.

Hopefully this will help a little in your own journey to understand Kubernetes.

A couple of months ago I released GoScan, which started more as a side-project useful for me to learn @golang.

The original idea was to port in Go a collection of python scripts I created years ago while taking OSCP, and then rarely used afterwards due to their “hacky” nature (hey, in OSCP time is everything, and you don’t really care about being stealthy, or “polite” against your targets).

I now wanted something more stable that I could use even during professional pentests, so I spent some time refactoring and refining the codebase.

This post is Part 1 of the “Offensive Infrastructure with Modern Technologies” series, and is going to provide an introduction to the HashiCorp suite, and to Consul in particular.

We will pave the way to start building an offensive infrastructure, by explaining how Consul can be used as a Service Mesh both in single and multi node deployments, in simple and hardened configurations.

Have you ever been in a network penetration test where the scope is so huge you end up with dozens of files containing Nmap scan results, each of which, in turn, contains a multitude of hosts? If the answer is yes, you might be interested in this blog post.

Following is the process I recently went through to find a way to triage the results, while enabling concurrent collaboration between team mates. We will see how using traditional “defensive” tools for Offensive security data analysis has advantages over the traditional grep when parsing and analysing data.

Finally, I’m going to provide the full source code of the setup I ended up with. Hopefully this will give someone else with a similar need some help in the future.
