Adversaries may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap. Occasionally, large numbers of username and password pairs are dumped online when a website or service is compromised and the user account credentials accessed. The information may be useful to an adversary attempting to compromise accounts by taking advantage of the tendency for users to use the same passwords across personal and business accounts.
Credential stuffing is a risky option because it could cause numerous authentication failures and account lockouts, depending on the organization's login failure policies.
Typically, management services over commonly used ports are used when stuffing credentials. Commonly targeted services include the following:
In addition to management services, adversaries may "target single sign-on (SSO) and cloud-based applications utilizing federated authentication protocols," as well as externally facing email applications, such as Office 365.(Citation: US-CERT TA18-068A 2018)

Comments
This control may mitigate brute force attacks by enforcing multi-factor authentication, enforcing strong password policies, and rotating credentials periodically. These recommendations are IAM best practices but must be explicitly implemented by a cloud administrator.

Password Checkup extension for Chrome displays a warning whenever a user signs in to a site using one of over 4 billion usernames and passwords that Google knows to be unsafe due to a third-party data breach. With reCAPTCHA Enterprise, you can identify credential stuffing attacks by utilizing Password Checkup to detect password leaks and breached credentials. Developers can factor this information into their score calculation for score-based site keys to help identify suspicious activity and take appropriate action.
