SPF and Dangling DNS Targets

The following examples of domains may be used for SPF sender policies for detecting forged emails, but may be available for purchase or takeover from subdomain hosts, resellers, domain brokers, and squatters.

DNS Institute recently performed a Dangling DNS study in which DNS mistakes or mismanagement may allow email impersonation or forgery via broken Sender Policy Framework (SPF) records. From a sample of 50,000 popular domains and domains owned by Fortune 500 companies, DNS Institute found over 80 SPF records that had policies using currently non-existent domains which may be available for purchase or assignment from domain resellers, brokers, squatters, registrars, or subdomain hosting providers.

SPF rules are published in DNS TXT records and are used primarily to define what IP addresses or networks are allowed to send emails with the SMTP HELO/EHLO identifying client hostname or SMTP MAIL-FROM email envelope address domain. SPF has optional parameters for defining the network addresses based on domain names. This includes fields for recursively using other policies via other DNS TXT records. Administrators authorize which network hosts are allowed to use their domain names and receiving SMTP email services can check this via these DNS records. (According to DNS Institute's research, over 75% of popular domains have TXT SPF records. Of those over 5% have policy configuration failures.)

SPF policies can be and are often managed by third-parties via different DNS zones, but because of typos or loss of control, malicious or unknown administrators can open up sender policies to allow recipients to accept emails from forged domains sent from others' addresses and networks.

Over two years ago, DNS Institute defined two then-novel techniques for detecting Dangling DNS records for domains hosted by domain resellers, squatters, and subdomain hosting providers, based on databases created and maintained by DNS Institute. They detected and reported mistakes which could lead to partial or complete domain (NS) or email (MX) takeover for various universities, government entities, Fortune 500 companies, and a security company.

DNS Institute provides a comprehensive DNS audit service with over 125 tests based on IETF/RFC standards, registry polices, government mandates, and vendor best practices, including for IPv6, EDNS, and DNSSEC.
