Building a Lab Network – Faux Corporate Networks

August 18, 2020 By Ken Smith

Last month, I mentioned the possibility of setting up a second virtual firewall in a lab environment to simulate a corporate network with mock internal and external spaces. I frequently do this for CTFs, student pentesting projects, and more. Offensive security training is rapidly moving towards realistic environments.

Building a Lab Network in Proxmox and Sophos UTM9

July 13, 2020 By Ken Smith

One of the best ways to acquire and maintain an offensive security skill set is to build a home lab and populate it with intentionally vulnerable machines. The most straightforward option is to simply spin up VMs in VirtualBox or VMWare Player and manage everything locally. To take things to the next level, however, you really need a hypervisor like ESXi or Proxmox. Nowadays, ... READ MORE

Enumerating Emails via Office.com

May 18, 2020 By Cameron Geehr

On a recent penetration test, I discovered that manually attempting to log into Office.com would give an indication as to whether an email address exists or not. Both of the techniques I was familiar with for Office365 username enumeration, using the Autodiscover API and ActiveSync, have both been fixed so this was definitely something worth exploring. I captured a few ... READ MORE

Socially Susceptible – Augmenting phishing with machine learning classifiers

May 12, 2020 By Austin Marck

Crafting sophisticated phishing campaigns is a necessary part of offensive tradecraft for testing security conscious and complex environments. The old adage goes "a chain is only as strong as its weakest link". Historically this chain has been people, but with increased resources and focus on testing, attackers have worked to find ways to increase their chances of gaining a ... READ MORE

Google Dorks

October 14, 2019 By Kyle Zeigler

Google Dork: Finding the Information You Don’t Know Exists Reconnaissance Reconnaissance. It’s a technique not unknown to most teenagers, and if we’re honest, we’ve all done it ourselves too – Googling the person you just met at the bar, Facebook stalking the new person at work, we all know the drill. This is the age of social media and data breaches, so we all know there’s a ... READ MORE

January 7, 2019 By Bryan

Spam Score

It's no secret that phishing is the top attack vector when it comes to external compromise. So when it comes to penetration testing this is a vector that we can not ignore.

Much like endpoint protection, there are a multitude of different spam filters and protection controls ... READ MORE

Fire and Forget: Meterpreter Automation

February 20, 2018 By Bryan

Throughout the past year I have been conducting routine phishing assessments for a client. For their final test of the year, our point of contact wanted something consequential for those who fell for this phish... Something 'kinetic' if you will. They requested a 'Blue Screen of Death' approach, to which I ultimately opted for a less potentially destructive method. I would send ... READ MORE
