Why Choose This Project

Subdomain takeovers are a common security risk where attackers gain control of unclaimed or misconfigured subdomains, potentially defacing websites, stealing data, or launching phishing campaigns. Traditional monitoring often misses unclaimed subdomains or DNS misconfigurations. This project provides a web-based platform to automatically detect vulnerable subdomains, helping organizations proactively secure their domain infrastructure.

What You Get

A web-based tool that scans all subdomains of a given domain, checks for misconfigurations or unclaimed resources, and identifies potential takeover risks. Administrators can generate reports, visualize vulnerable subdomains, and receive alerts when new subdomains become vulnerable. Ideal for security teams, pentesters, and DevOps engineers to maintain domain security hygiene.

Key Features

Technology Stack

Working Flow

1. User Login – Secure authentication for admins or security personnel.

2. Domain Input – User provides a root domain to scan.

3. Subdomain Enumeration – System enumerates all subdomains using public records and DNS queries.

4. Vulnerability Check – Each subdomain is checked for dangling CNAMEs, unclaimed cloud resources, and misconfigurations.

5. Risk Assessment – Assign severity based on the likelihood of takeover and criticality of the service.

6. Report Generation – Generate a report listing vulnerable subdomains, findings, and recommended remediation.

7. Dashboard & Alerts – Visualize safe vs vulnerable subdomains and send notifications for critical findings.

8. Audit Logging – Track scans, detected vulnerabilities, and notifications for compliance.
