As 2024 nears its end, we feel it is a great time to look back at what we achieved in 2024.

TLDR: No one would call this a quiet year for Outflank.

OST Releases: New Tools and Major Releases

22 releases! We managed to put out 22 releases of OST in 2024.

Rapid development remains a cornerstone of OST and has allowed us to match the pace of evolving threat landscape to deliver cutting edge tools and capabilities. We have a release note tracker covering every release, but highlights include:

EDR Presets

With EDRs becoming more powerful, and bypasses requiring more EDR-specific tricks, it was becoming hard to keep track of the countless options OST operators have for evasion of those EDRs.

We have rebranded our commercial C2 framework from Stage1 to Outflank C2 to reflect its continued growth and functionality, including native implant support for Windows, macOS, and Linux.

TLDR: We open up our internal toolkit commercially to other red teams. This post explains why.

Is blue catching your offensive actions? Are you relying on public or even commercial tools, but are these flagged by AV and EDR? Hesitant on investing deeply in offensive research and development? We’ve been there. But several years ago, we made the switch and started heavily investing in research. Our custom toolset was born.

Today we open up our toolset to other red teams in a new service called Outflank Security Tooling, abbreviated OST. We are super(!) excited about this. We truly think this commercial model is a win-win and will help other red teams and subsequently many organisations worldwide. You can find all the details at the product page. But there is more to be explained about why we do this,

This is part 3 of a multipart blog series on RedELK: Outflank’s open sourced tooling that acts as a red team’s SIEM and helps with overall improved oversight during red team operations.

In part 1 of this blog series I discussed the core concepts of RedELK and why you should want a tool like this. In part 2 I described a walk-through on integrating RedELK into your red teaming infrastructure. Read those blogs to get a better background understanding of RedELK.

For this blog I’ve setup and compromised a fictitious company. I use the logs from that hack to walk through various options of RedELK. It should make clear why RedELK is really helpful in gaining operational oversight during the campaign.

This is part 2 of a multipart blog series on RedELK: Outflank’s open sourced tooling that acts as a red team’s SIEM and also helps with overall improved oversight during red team operations.

In part 1 of this blog series I have discussed the core concepts of RedELK and why you should want something like this. In this blog post I will walk you through integrating RedELK into your red teaming infrastructure. In future parts I will explain the core functionality of RedELK, and on the alarming of detection by blue teams.

This multi-part blog post is about a tool we released: RedELK. In a few words you can describe it as a “Red Team’s SIEM”, although it actually does a few more things to ease the life of red teams. We released it right after our talk at BruCON 2018, and you may have already seen it at our GitHub. But until now we haven’t had the time to articulate our reasoning and give it a proper introduction.

This first part covers our reasoning. A the second part (soon to be released) we’ll dive into the technical details, explain basic usage and show you how you can benefit from using it as a red teamer.

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.
