Question
Consider the case that the admin of goodwebsite.com hosts the email server at 1.1.1.1 and add the 1.1.1.1 into its SPF record. Later on, the admin decide to host the email server to 2.2.2.2, but forget to remove the 1.1.1.1 IP address in the SPF record. Assume goodwebsite.com does not have DKIM record. Can attackers obtain 1.1.1.1 and send emails on behalf of goodwebsite.com? Provide 1-2 sentence explanation.
Solution
Yes, attackers could potentially exploit this oversight. If the SPF record of goodwebsite.com still includes the IP address 1.1.1.1, then emails sent from this IP address would pass the SPF check, even though the email server is no longer hosted at that address. This could allow an attacker who has control over the 1.1.1.1 IP address to send emails that appear to be from goodwebsite.com.
