  • Email verification deficiencies, expiration of password reset links, and password complexity policies
  • DNS issues (i.e. mx records, SPF records, etc.)
  • Clickjacking/UI redressing with minimal security impact
  • Email or mobile enumeration (E.g. the ability to identify emails via password reset)

  • Issues related to unsafe SSL/TLS cipher suites or protocol version
  • Content spoofing
  • Cache-control related issues
  • Exposure of internal IP address or domains
