SSL.com Slip-Up: How a Simple Bug Opened the Door to Fake SSL Certificates
SSL.com’s vulnerability let attackers issue valid SSL certificates for domains by exploiting a bug in its email-based domain verification method. This flaw allowed anyone to obtain certificates using just an email address linked to a domain, posing significant security risks like creating fake websites and intercepting communications.

Hot Take:
Even in the world of high-stakes cybersecurity, sometimes the weakest link is just an email away. SSL.com, you’ve been caught with your digital pants down, and now everyone can see your… vulnerabilities. Next time, maybe double-check who you’re trusting with the keys to the kingdom—your domain, that is.
Key Points:
- SSL.com had a vulnerability in its email-based domain verification process.
- This flaw allowed attackers to obtain valid SSL certificates without full domain control.
- The issue was linked to the email verification method using MX records.
- SSL.com issued multiple certificates by mistake, affecting various domains.
- SSL.com has since disabled the problematic verification method and admitted fault.
