Automated AD and Windows test lab deployments with Invoke-ADLabDeployer

We are happy to introduce Invoke-ADLabDeployment: a PowerShell project that helps you to quickly deploy a virtual test environment with Windows servers, Windows desktops, Office, Active Directory and a networking setup with multiple broadcast segments, all running on your local Hyper-V environment.

It is an in-house developed tool that we use heavily during our red teaming engagements. We use this to quickly spin-up lab environments that resemble the target environment. This way we can better develop and test our attacks, as well as investigate what artefacts we might leave behind.

We feel it is time to give back to the community and allow other red and blue teams to benefit from this. You can read more about its functionality and why we developed this below. Or you can go straight to the code and manual on our github.

Public password dumps in ELK

Passwords, passwords, passwords: end users and defenders hate them, attackers love them. Despite the recent focus on stronger authentication forms by defenders, passwords are still the predominant way to get access to systems. And due to the habit of end users reusing passwords, and the multitude of public leaks in the last few years, they serve as an important attack vector in the red teamer’s arsenal. Find accounts of target X in the many publicly available dumps, try these passwords or logical iterations of it (Summer2014! might very well be Winter2018! at a later moment) on a webmail or other externally accessible portals, and you may have got initial access to your target’s systems. Can’t find any accounts of your target in the dump? No worries, your intel and recon may give you private email addresses that very well may be sharing the password with the target’s counter parts.
