Summary

  • A subdomain takeover is a type of security breach that can occur when a subdomain becomes available for registration but points to a third-party service that is no longer active.
  • This could provide an opportunity for malicious actors to take over the subdomain and potentially gain access to sensitive information.
  • To avoid this situation, it is important to ensure that all subdomains are correctly mapped to active services and that any unused subdomains are promptly registered or deleted.
  • Furthermore, security professionals should keep an eye on the services to which their subdomains are linked and be prepared to react swiftly if those services are discontinued.
  • Abhijeet Kumawat, a cybersecurity researcher, has written a detailed article on his Medium blog about subdomain takeovers and offers practical advice and real-world examples from the field.
