Subdomain hijacking refers to taking over a website's subdomain without the owner's permission or knowledge. Organizations often use subdomains to create separate websites or services, such as blog.example.com or shop.example.com.

In subdomain hijacking, an attacker identifies a subdomain not being used or secured correctly and then registers it for themselves. They can then use the subdomain to host malicious content and phishing pages or redirect traffic to their own website, thereby exploiting the reputation and trust associated with the legitimate website.

This attack can lead to various security and privacy risks for the website owner and its users. It can also damage the reputation of the legitimate website, as it may be associated with malicious activities. To prevent subdomain hijacking, website owners should carefully manage their domain and subdomain registrations, regularly monitor their DNS records, and implement security measures such as SSL/TLS certificates and DNSSEC.

ThreatNG Security can help prevent subdomain hijacking by providing visibility into the organization's digital footprint, identifying potential vulnerabilities and misconfigurations, monitoring for potential threats, and assessing the organization's security posture. By combining these capabilities, the solution can help organizations identify and remediate vulnerabilities before attackers can exploit them and provide a comprehensive approach to subdomain hijacking prevention.
