Creating a C2 Infrastructure on AWS

2025-02-15

In this lesson, you will learn how to create a secure Command and Control (C2) infrastructure on the AWS cloud. We will start by discussing what a C2 infrastructure is, its design, and then proceed to build one from scratch.

Practice-Verified Codes and Commands

1. Setting Up AWS CLI

Install and configure the AWS CLI if you haven’t already:

sudo apt update 
sudo apt install awscli 
aws configure 

Provide your AWS Access Key, Secret Key, region, and output format when prompted.

2. Creating an EC2 Instance for C2 Server

Use the following command to create an EC2 instance:

aws ec2 run-instances --image-id ami-0abcdef1234567890 --instance-type t2.micro --key-name MyKeyPair --security-group-ids sg-903004f8 --subnet-id subnet-6e7f829e 

Replace the placeholders with your specific AMI ID, key pair, security group, and subnet ID.

3. Configuring Security Groups

Ensure your security group allows inbound traffic on ports 80 (HTTP) and 443 (HTTPS):

aws ec2 authorize-security-group-ingress --group-id sg-903004f8 --protocol tcp --port 80 --cidr 0.0.0.0/0 
aws ec2 authorize-security-group-ingress --group-id sg-903004f8 --protocol tcp --port 443 --cidr 0.0.0.0/0 

4. Installing C2 Software

SSH into your EC2 instance and install your preferred C2 software, such as Covenant or Empire:

sudo apt update 
sudo apt install git -y 
git clone https://github.com/cobbr/Covenant 
cd Covenant 
./build.sh 

5. Configuring DNS for C2

Use Route 53 to configure a domain for your C2 server:

aws route53 create-hosted-zone --name myc2domain.com --caller-reference my-c2-reference 

6. Testing the C2 Infrastructure

Deploy a test payload and ensure it connects back to your C2 server:

./Covenant/Covenant/bin/Debug/netcoreapp3.1/Covenant.Listener --urls http://0.0.0.0:80 

What Undercode Say

Creating a C2 infrastructure on AWS requires a deep understanding of cloud services, networking, and security. AWS provides a robust platform for building scalable and secure C2 infrastructures, but it’s crucial to follow best practices to avoid detection and ensure operational security.

When setting up your C2 infrastructure, always use encrypted communication channels (HTTPS) and regularly rotate your AWS credentials. Leverage AWS services like CloudTrail and CloudWatch to monitor for suspicious activity. Additionally, consider using AWS Lambda for automating tasks such as payload generation and deployment.

For Linux users, mastering commands like netstat, tcpdump, and `iptables` is essential for monitoring and securing your C2 server. On Windows, tools like PowerShell and Sysinternals can help you manage and secure your infrastructure.

Finally, always stay updated with the latest cybersecurity trends and tools. Resources like OWASP and MITRE ATT&CK provide valuable insights into offensive and defensive techniques.

By combining AWS’s flexibility with strong cybersecurity practices, you can build a resilient C2 infrastructure that meets your operational needs while minimizing risks.
