Introducing PolarDNS: The Revolutionary Open-Source Tool for DNS Security Analysis and Penetration Testing

 

DNS (Domain Name System) is crucial in vulnerability research and pentesting, decoding human-readable domain names into IP addresses. This analysis can reveal attack vectors like subdomain enumeration, misconfigurations, and DNS-related vulnerabilities. Oryxlabs’ launch of PolarDNS, a free, Python-based DNS server, marks a significant advancement in this domain.

PolarDNS Overview

PolarDNS provides operators with full control over DNS responses, essential for testing DNS resolvers, clients, libraries, parsers, and any software handling DNS information. It supports both UDP and TCP protocols and generates non-standard, non-compliant, and malformed DNS responses.

Key Features and Response Modifiers

PolarDNS comes with built-in features and modifiers, allowing the creation of various DNS responses. This capability is vital for testing technical robustness and uncovering vulnerabilities like Sloth domain attacks, Phantom domain attacks, and more. Its unique features enable testing of RFC compliance and functional robustness.

Installation and Usage

Installing and running PolarDNS requires Python 3.10 or newer and PyYAML. The server listens on localhost by default and handles DNS queries on UDP and TCP ports 53. Users can test the server using commands like dig always.yourdomain.com @127.0.0.1 in both UDP and TCP modes.

Unique Aspects of PolarDNS

Sumit Dhar from OryxLabs highlights PolarDNS’s ability to act as a rogue authoritative DNS server and craft custom DNS responses. Its versatility and control over the DNS layer make it a powerful tool for security evaluations.

Future Plans for PolarDNS

OryxLabs aims to build a community around PolarDNS, enhancing its features and exploring integrations with other cybersecurity platforms. The tool is available for free on GitHub.
