Docker for Kali Linux: A Game-Changer in Penetration Testing

As penetration testers, we often find ourselves in situations where we need to deploy specific tools or devices within a client's environment, without having them physically present. This is especially common during internal pentest engagements or red team exercises. In one of our recent projects, we faced such a scenario and discovered the power of Docker for Kali Linux.

Our story begins with an Internal Pentest engagement where we were tasked with sending a phone-home device instead of a consultant to gain access to the client's environment. While we managed to breach the perimeter through a fairly uncommon application server, our initial foothold was lost when the client closed it due to the risk of lateral movement. This led us to identify a new opportunity and gain access via their Citrix deployment.

In this situation, we realized that having nmap or Metasploit deployed somewhere inside the client's environment would have been incredibly useful. However, we didn't have these tools immediately available. This is where Docker for Kali Linux came into play.

Using Docker, we were able to containerize our desired tools and deploy them within the client's environment. This allowed us to gain a foothold once again and demonstrate lateral movement capability. The flexibility and ease of use that Docker provides made it an ideal solution for this scenario.

In this blog post, we'll explore how we used Docker for Kali Linux to overcome the challenges we faced during our Red Team engagement. We'll delve into the benefits of containerization in penetration testing and provide practical tips on how to get started with Docker for Kali Linux.

By leveraging Docker for Kali Linux, we were able to overcome the limitations of not having immediate access to our desired tools. This technology has opened up new possibilities for us as penetration testers, allowing us to be more efficient and effective in our engagements.

In conclusion, Docker for Kali Linux is a game-changer in penetration testing. Its ability to containerize tools and deploy them within a client's environment makes it an essential tool for any penetration tester looking to stay ahead of the curve.
