GCPwn: A Pentester's GCP Tool

Abstract: When discussing the various cloud providers within the last decade, Google Cloud Platform (GCP) is often seen as the smaller provider following AWS and Azure with regards to market share. While GCP might appear smaller than its rival cloud providers, it still is very much in use today, and with this use comes the opportunities for developing pentesting tools. As I've been learning GCP over the last year, I have been making a framework in python (much like Pacu for AWS) specifically for GCP. This includes enumeration modules for some of the core services (Cloud Storage, Cloud Functions, Cloud Compute, IAM) along with the incorporation of numerous exploit modules, many of them rooted in Rhino Security's currently public GCP exploit repository (https://github.com/RhinoSecurityLabs/.... In addition, the framework is built such that it should be easy for a first-time GCP user or beginner to code and develop modules that focus on purely navigating individual resources and easily drop those into the framework. The overall goal is to make an up-to-date, maintained enumeration and exploit toolset for GCP pentesters/red teams/researchers alike that reduces the barrier of entry for learning GCP by allowing average users to make their own modules that easily incorporate with the overall framework. Bio: Originally from southern CA, I am currently a senior security consultant for NetSPI based out of Minneapolis, MN. My assessment experience includes web applications, AWS, GCP, and external networks. I spoke about AWS organizations at fwd:cloudsec 2023 with most of the talk summarized in the 2 part blogpost here: https://www.netspi.com/blog/technical.... I got accepted to speak at fwd:cloudsec 2024 for a new tool I've been making to pentest GCP environments (mirroring Pacu-like structure). In my spare time I like to pursue bug bounties if the opportunity arises, play videogames, assume the role of dungeon master every so often, and just hang out.
