Pentesting Industrial Control Systems

By: Paul Smith

Overview of this book

The industrial cybersecurity domain has grown significantly in recent years. To completely secure critical infrastructure, red teams must be employed to continuously test and exploit the security integrity of a company's people, processes, and products. This is a unique pentesting book, which takes a different approach by helping you gain hands-on experience with equipment that you’ll come across in the field. This will enable you to understand how industrial equipment interacts and operates within an operational environment. You'll start by getting to grips with the basics of industrial processes, and then see how to create and break the process, along with gathering open-source intel to create a threat landscape for your potential customer. As you advance, you'll find out how to install and utilize offensive techniques used by professional hackers. Throughout the book, you'll explore industrial equipment, port and service discovery, pivoting, and much more, before finally launching attacks against systems in an industrial network. By the end of this penetration testing book, you'll not only understand how to analyze and navigate the intricacies of an industrial control system (ICS), but you'll also have developed essential offensive and defensive skills to proactively protect industrial networks from modern cyberattacks.

Script access

In the previous section, we discussed the level of access and control that we can perform by gaining UI control. In this section, we are going to look at trying to gain deeper access into the SCADA server, which will allow us to bypass the UI control and communicate directly with the physical equipment. In our case, this would be Koyo Click.

From our workstation, we want to test whether our SCADA server is running some sort of file share that is open for easy intranet file transfers. Run the following command:

ftp 192.168.2.11

This will bring us to a login prompt. I tend to always check whether a service is running with anonymous credential access. In this case, we will use the username anonymous. As you can see from the 230 Login successful response, we have anonymous access:

Next, we will want to switch to the pub folder and check our access rights. We can quickly do this by creating a folder...
