Subhunter

A fast subdomain takeover tool

Description:

Subdomain takeover is a common vulnerability that allows an attacker to gain control over a subdomain of a target domain and redirect users intended for an organization's domain to a website that performs malicious activities, such as phishing campaigns, stealing user cookies, etc. It occurs when an attacker gains control over a subdomain of a target domain. Typically, this happens when the subdomain has a CNAME in the DNS, but no host is providing content for it. Subhunter takes a given list of subdomains and scans them to check this vulnerability.

Features:

• Auto update
• Uses random user agents
• Built in Go
• Uses a fork of fingerprint data from well known sources (can-i-take-over-xyz)
