The Secrets Behind Subdomain Takeovers Nobody Shares
1 min read
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breach that can occur when a subdomain becomes available for registration but points to a third-party service that is no longer active.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.
