शब्दों की व्याख्या
अक्सर पूछे जाने वाले प्रश्न
What is a subdomain takeover?
When a DNS record points to a service account that was deleted, an attacker can create that account and serve content on your subdomain. See the guide.
How do I fix a finding?
Delete the DNS record, or recreate the service resource under your own account.
Why might subdomains be missing?
The tool uses public certificate logs, which only list subdomains that had certificates issued.
