nextnet

Nextnet is a command-line tool designed for cybersecurity professionals to discover pivot points within specified networks. Pivot points are hosts or systems that can be leveraged to extend access deeper into a target environment during penetration testing or red team engagements.

The tool is particularly useful in scenarios where initial access has been gained to a network segment, and further exploration is needed to identify intermediate systems that can facilitate lateral movement. By probing networks, nextnet helps map out potential expansion paths efficiently.

Packaged for Kali Linux, it offers a lightweight solution with minimal dependencies, making it suitable for rapid deployment in testing environments.

Nextnet operates by taking one or more CIDR notations as input and probing the specified networks for potential pivot points. Written in Go, it performs network scans or checks using lightweight, efficient techniques to identify suitable hosts. The exact probing mechanisms are implemented in Go for performance and portability, targeting characteristics that define viable pivot points such as open services or specific configurations.
