Introduction

In this article, we will be exploring the Havoc C2 framework, a popular C2 framework that provides a GUI similar to Cobalt Strike. We will start by giving an overview of the framework and then walk through its setup and installation process. After that, we will cover the basic usage of the Havoc C2 framework, including setting up a listener and generating payloads. As a bonus, we will also demonstrate how to bypass Windows Defender successfully and obtain a callback to the Havoc C2 server using a C++ Shell Code loader. So without further ado, let's dive into the world of Havoc C2 and explore its capabilities.

Overview of Havoc C2 Framework

The Havoc C2 framework is a powerful command and control framework that is widely used by red teamers and penetration testers. It offers a user-friendly GUI similar to Cobalt Strike, making it easier for users to navigate and utilize its features. With Havoc C2, users can set up listeners, generate payloads, perform file management, execute shell commands, capture screenshots, and much more. It also provides a Windows Defender bypass mechanism, allowing users to evade detection and maintain persistence on the target system. Overall, Havoc C2 is a versatile framework with a wide range of capabilities.

Setting up Havoc C2 Framework

To get started with the Havoc C2 framework, we need to follow the installation instructions provided in the official documentation. The installation process involves downloading and configuring the necessary dependencies, setting up SSH access, and executing the server and client components of Havoc C2. However, it's important to note that some users may encounter issues during the installation process, such as compatibility errors or authentication problems. In such cases, troubleshooting and additional configurations may be required. But once the framework is properly set up, users can proceed to the next step of utilizing its functionality.

Basic Usage of Havoc C2 Framework

Once Havoc C2 is up and running, users can start exploring its various features. The first step is to set up a listener, which allows the framework to receive incoming connections from compromised hosts. After the listener is active, users can generate payloads for specific targets. The generated payloads can be customized Based on user preferences and desired functionality. Once a payload is generated, it can be transferred to the target system and executed. This establishes a connection between the compromised system and the Havoc C2 server, providing control and access to the target.

Bypassing Windows Defender with Havoc C2 Framework

One of the notable features of Havoc C2 is its ability to bypass Windows Defender, a popular antivirus program. By utilizing a C++ Shell Code loader, users can successfully execute payloads On Target systems without triggering Windows Defender alerts. This bypass mechanism involves encrypting the demon Shell Code and making specific modifications to the loader code. By performing these steps, users can evade detection and maintain their presence on the compromised system. It's important to note that this bypass technique requires careful implementation and testing to ensure effectiveness.

File Management with Havoc C2 Framework

Apart from executing commands on target systems, Havoc C2 also provides file management capabilities. Users can Interact with the compromised system's file system through the framework's user interface. This allows for tasks such as uploading and downloading files, creating directories, modifying file permissions, and executing file operations remotely. The file management feature of Havoc C2 adds versatility to the framework and enables users to perform a wide range of post-exploitation activities.

Using the Shell Command in Havoc C2 Framework

In addition to file management, Havoc C2 offers a shell command feature that allows users to execute arbitrary commands on the compromised system. This gives users the ability to perform various actions, such as running system utilities, executing scripts, manipulating system settings, and interacting with the command-line interface of the target system. The shell command feature provides a flexible and powerful way to control the compromised system and carry out specific tasks as needed.

Capturing Screenshots with Havoc C2 Framework

Another useful feature of Havoc C2 is the ability to capture screenshots of the target system. This feature comes in handy when conducting reconnaissance or monitoring activities on the compromised system. Users can remotely trigger the target system to capture a screenshot and retrieve it through the Havoc C2 interface. This feature allows users to Gather visual information about the target system and make informed decisions based on the captured screenshots.

Demonstration of Windows Defender Bypass

To showcase the effectiveness of the Windows Defender bypass mechanism in Havoc C2, we will demonstrate the entire process step by step. We will start by modifying the demon Shell Code and the C++ loader code, ensuring that they evade Windows Defender detection. Next, we will compile the modified code and transfer it to a Windows machine protected by Windows Defender. Upon execution, we will observe the successful bypass of Windows Defender and the establishment of a callback on the Havoc C2 server. This practical demonstration highlights the capabilities of Havoc C2 in evading antivirus detection and maintaining persistence on target systems.

Conclusion

In this article, we have explored the Havoc C2 framework, its features, and its capabilities. We have discussed the setup and installation process, the basic usage of Havoc C2, the bypassing of Windows Defender, and the file management and shell command features. Through practical demonstrations, we have showcased the efficacy of Havoc C2 in maintaining control over compromised systems and evading detection. Havoc C2 is a powerful tool for red teamers and penetration testers, providing them with a comprehensive framework to carry out their activities effectively and efficiently.
