Emily Eaton Assigned Admin Role to Noah Nichols[+]
Standard.AdminRoleAssigned
Summary

On July 23, 2024, an alert was triggered when Emily Eaton, identified by her email emily.eaton@thisisarealcompany.com and serving as VP of Information Technology, assigned the roles/owner admin privileges to Noah Nichols at noah.nichols@thisisarealcompany.com within the GCP environment of project integration-419004. The assignment occurred at 19:16:41 UTC, with the alert following at 19:23:16 UTC. The IP address used by Emily Eaton during this assignment was 256.212.1.10, which is associated with Amazon.com, Inc. and located in Boardman, Oregon, United States. This IP address does not match her typical usage from a Comcast Cable Communications IP in Bellevue, Washington.

Noah Nichols, whose job title is "Marketing Operations Specialist," does not typically require admin privileges, raising concerns about the appropriateness of this privilege escalation. Following the assignment, Noah attempted to create instances within the same project, specifically instance-20240723-192605 and instance-20240723-193102, but encountered errors. These activities, combined with the unusual IP address used for the admin role assignment, suggest a potential security issue within the GCP project.

ConclusionSuspicious
The alert is deemed suspicious and additional analysis is required in order to make a definite determination as to whether it is malicious or benign.
