Adversaries may create email accounts that can be used during targeting. Adversaries can use accounts created with email providers to further their operations, such as leveraging them to conduct Phishing for Information or Phishing. Adversaries may also take steps to cultivate a persona around the email account, such as through use of Social Media Accounts, to increase the chance of success of follow-on behaviors. Created email accounts can also be used in the acquisition of infrastructure (ex: Domains).
