subdomain-takeover

Subdomain takeover occurs when DNS records point to deprovisioned or unclaimed third-party resources. Attackers exploit this by claiming the dangling resource, gaining control over the target subdomain to host malicious content or intercept traffic.

Exploiting NS and MX record takeovers involves detecting records that point to deprovisioned services and executing provider-specific takeover procedures. This allows you to claim the authoritative nameserver or mail handling resources for the target domain.

The best way to identify wildcard DNS risks is to scan for wildcard CNAMEs that resolve to unclaimed resources. This process reveals mass subdomain takeover opportunities where a single misconfigured wildcard record exposes multiple subdomains.

Yes, subdomain takeover scanning relies on provider fingerprinting by matching error responses from CNAME targets against known provider fingerprints. This confirms whether a specific cloud service or hosting provider has an unclaimed resource vulnerable to takeover.

Yes, you can use this Skill for offensive security and domain control scenarios. It provides step-by-step takeover procedures for claiming unclaimed resources, enabling an attacker to gain full control over a target company's subdomain and its associated resources.
