The Hunter’s Den: Command and Control

The Hunter’s Den blog series aims to go beyond framework and theory and dig into practical tips and techniques for threat hunting. In our previous post, we examined the practical ways that one can hunt for Internal Reconnaissance. In this post, we will take a look at how to hunt for Command and Control (C2) activity. Command and control is the process through which an attacker establishes a connection with a compromised asset that they have taken control of in a target network. C2 is a critical step in the process of carrying out an attack on a network. It is a category broad enough that it has its own kill chain step (KC6, “Command and Control”). Although it is a broad tactic, this post will survey the different ways that it might generally be carried out by an adversary.


What is Threat Hunting in Cybersecurity Defense

Threat hunting involves several activities that you can do to find hackers on your network. The reason we need this is that the threats are to some extent intelligent operators who adapt to the defenses you set up in your network – they find workarounds for each new hurdle you throw at them. Therefore, the defense needs to get smart and use a wide arsenal of analysis techniques to find the threats; meaning analysis of data that can indicate that an intrusion has occurred.
