NetAtlas C2 Server Search: Detecting Command and Control Servers with Netlas API

C2 Search Netlas is a Java utility designed to detect Command and Control (C2) servers using the Netlas API. It provides a straightforward and user-friendly CLI interface for searching C2 servers, leveraging the Netlas API to gather data and process it locally.

Usage

To utilize this terminal utility, you’ll need a Netlas API key. Obtain your key from the Netlas website.

After acquiring your API key, execute the following command to search servers:

c2detect -t <TARGET_DOMAIN> -p <TARGET_PORT> -s <API_KEY> [-v]

Replace <TARGET_DOMAIN> with the desired IP address or domain, <TARGET_PORT> with the port you wish to scan, and <API_KEY> with your Netlas API key. Use the optional -v flag for verbose output. For example, to search at the google.com IP address on port 443 using the Netlas API key 1234567890abcdef, enter:

c2detect -t google.com -p 443 -s 1234567890abcdef

Release

To download a release of the utility, follow these steps:

  • Visit the repository’s releases page on GitHub.
  • Download the latest release file (typically a JAR file) to your local machine.
  • In a terminal, navigate to the directory containing the JAR file.
  • Execute the following command to initiate the utility:
java -jar c2-search-netlas-<version>.jar -t <ip-or-domain> -p <port> -s <your-netlas-api-key>

Docker

To build and start the Docker container for this project, run the following commands:

docker build -t c2detect .
docker run -it --rm \
  c2detect \
  -s "your_api_key" \
  -t "your_target_domain" \
  -p "your_target_port" \
  -v

Source

To use this utility, you need to have a Netlas API key. You can get the key from the Netlas website. Now you can build the project and run it using the following commands:

./gradlew build
java -jar app/build/libs/c2-search-netlas-1.0-SNAPSHOT.jar --help

This will display the help message with available options. To search for C2 servers, run the following command:

java -jar app/build/libs/c2-search-netlas-1.0-SNAPSHOT.jar -t <ip-or-domain> -p <port> -s <your-netlas-api-key>

This will display a list of C2 servers found in the given IP address or domain.

Set Up a UFW Firewall on Ubuntu 18.04: Allow, Deny, and Manage

A properly configured firewall is one of the most important layers of security for any internet-facing server. UFW (Uncomplicated Firewall) is a user-friendly front-end for managing iptables rules that ships pre-installed on Ubuntu. Its defaults are sensible: block all incoming connections, allow all outgoing connections. No outside traffic reaches your server unless you explicitly open a port. This guide covers how to configure a UFW firewall on Ubuntu 18.04, from setting default policies and application profiles to writing allow and deny rules for specific ports, IPs, and subnets. <strong>Prerequisite:</strong>&nbsp;You&nbsp;need&nbsp;sudo&nbsp;access.
