What stood out

  • Anyone can send email as your domain: There is no DMARC record on github.io, so anyone can send email that looks like it comes from you and phish your customers, staff, or suppliers.
  • Missing Strict-Transport-Security: HSTS is not set, so browsers can be tricked into loading your site over insecure HTTP.
  • Missing X-Frame-Options: Your pages can be embedded in a hidden frame on another site (clickjacking).
  • Missing X-Content-Type-Options: Browsers may guess file types on your site, which can enable some attacks.
