Subdomain Takeover Vulnerability Assessment and Scoring

Discover, Assess, Report, and Monitor for Susceptibility to Subdomain Takeover

A subdomain takeover vulnerability occurs when a third-party service or application is no longer in use but linked to a subdomain of an organization. In this scenario, an attacker can register or take control of the expired domain or service and use it to redirect users to malicious websites or perform other nefarious activities.

ThreatNG discovers, assesses, scores, and monitors for the presence and susceptibility to subdomain takeover vulnerabilities by identifying all subdomains, analyzing each for vulnerabilities, assigning a Subdomain Takeover Susceptibility Score, and continuously monitoring for changes.

The ThreatNG "Subdomain Takeover Susceptibility Score" measures a website's vulnerability to external attackers taking over its subdomains for malicious activities. Monitoring this score helps website owners identify and address potential vulnerabilities, reducing the risk of data breaches, financial loss, or damage to reputation.

Subdomain Takeover Susceptibility Score

Testing for Subdomain Takeover Susceptibility is a part of the Domain Intelligence Module, which investigates all aspects of domains and subdomains, their DNS records, SSL certificate statuses, and other relevant factors. Using this module, organizations can identify potential vulnerabilities associated with subdomain takeover attacks and take proactive measures to mitigate the risks.

Assessing and Monitoring for Subdomain Takeover Susceptibility Can Mitigate Risks in External Attack Surface, Digital Presence, Brand, Third Parties, and Supply Chain

External Attack Surface

Identify and prioritize vulnerable subdomains in their external attack surface to focus efforts on remediating high-risk vulnerabilities and reducing their overall attack surface.

Digital Risk

Organizations can avoid subdomain takeover attacks by continuously monitoring subdomains for potential vulnerabilities and taking proactive measures to mitigate risks resulting in maintaining a secure digital presence and protecting their assets from cyber threats.

Third Party and Supply Chain Risk Management

Assess the security posture of third-party vendors, suppliers, and partners to help identify potential risks associated with your supply chain and take appropriate measures to mitigate these risks.

Due Diligence

During mergers and acquisitions, organizations can assess the security posture of the target company's digital footprint, especially for susceptibility to subdomain takeovers resulting in identifying potential risks and vulnerabilities that could impact the deal's overall value.

Brand Protection

Subdomain takeover attacks can tarnish an organization's brand reputation by redirecting traffic to malicious sites. Organizations can protect their brand reputation and maintain customer trust by proactively identifying and addressing subdomain takeover vulnerabilities.
