Goal
Detects when a GitLab user changes their associated email address and then signs in using the new email.
Strategy
This rule monitors the user_email_changed_and_user_signed_in GitLab audit event. Email address changes can be used by attackers to maintain persistence after compromising an account.
Triage and response
- Verify if
{{@usr.name}} has a legitimate business reason to change their email address in GitLab. - Review authentication logs around the time of the email change to identify any unusual access patterns or geographic anomalies.
- Examine recent GitLab activity for the user account to determine if any unauthorized actions were performed after the email change.
- Validate that the new email address belongs to the organization’s domain or is otherwise authorized for use.
