The complete guide to SubdoMailing
Subdomain-based email attacks exploit weak spots in DMARC protection. Threat actors send messages from authentic-looking subdomains that pass security checks, making it easy to impersonate trusted brands and trick recipients.
This guide covers:
- Why SubdoMailing is a growing threat you can’t ignore
- The risks posed by dangling DNS records in your domain setup
- Practical steps to protect your organization right now
Frequently asked questions
Red Sift has free email security tools that check the overall health of your email setup and whether you’ve been impacted by SubdoMailing.
Investigate will automatically check whether your email sending domain has critical security protocols set up correctly, including DMARC, SPF, DKIM, FCrDNS, TLS, BIMI, and MTA-STS. It will also tell you if any ‘SubdoMailers’ have been found.
Should Investigate reveal any ‘SubdoMailers’ - also known as poisoned includes - the SPF Checker allows you to visualize them in a dynamic ‘SPF tree’, allowing you to quickly pinpoint where they are and speed up remediation efforts.
If compromised includes are detected in your SPF record, your domain is vulnerable to spoofing attacks. We recommend you remove these entries from your SPF record immediately. Learn how with our free guide to SubdoMailing above.
