This is the second scenario in the CloudGoat series, and it is the simplest one at the time of writing. We start off as a high-privileged user who can change their defualt policy version. One of the versions of this user’s managed policy allows for performing any action on any resource. The user can therefore change their default version to this policy version and obtain Administrator access.

The second video in the GCP series in which the threat actor must leverage an SSRF vulnerability to exploit a misconfigured application. The application supports the gopher protocol which can be abused to query the metadata service.
The first video in the GCP series features a scenario where participants are provided with a URL leading to a misconfigured storage bucket serving image files, prompting them to fuzz potential files, discover a backup zip file due to the entity being set to "Public" with "allUsers" granted Reader access, and completing the challenge by decrypting the zip file.
The objective of this scenario was to gain access to an RDS instance. We were provided with the credentials of two different users, and exploited this AWS environment in two different ways.
