A review into Industroyer’s Command & Control Protocol
2017 by Adam Chester
Recently the world was introduced to ‘Industroyer‘, a malware variant with a focus on compromising industrial control systems (ICS). Members of the security community are speculating if this malware sample was responsible for the power outage in Kiev during 2016. What is known is that this malware targets ICS with efficiency. With nation state attacks ever dominating the news, we take a keen interest in emerging threats.
Working in offensive security, we are approached and asked about such threats from customers, whether that is to help simulate a threat actor during a red-team engagement, or simply to provide advice on preventative measures. With this in mind, we wanted to explore Industroyer and understand just how it operated when controlled.
We have determined the Command & Control (C & C) protocol used to issue commands to infected hosts and return results. Additionally, we have developed ‘Indushell‘ which implements that protocol enabling the community to now interact with Industroyer.
The following video shows exactly how to use Indushell:
Today we release:
Our Industroyer_command_and_control_protocol whitepaper – this documents our progress in analysing the backdoor component of the malware, understanding how commands are sent to the backdoor, and finally we will simulate an attackers C&C server controlling a malware sample
