## Summary of Changes Hello @barakharyati, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request, despite being labeled as a 'test' and 'do not merge', introduces critical security vulnerabilities. It systematically dismantles the existing IAM infrastructure and replaces it with a mechanism designed to execute arbitrary shell commands. These commands are configured to exfiltrate sensitive repository and cloud credential information to an external server, posing a severe risk of data breach and unauthorized access to project resources. ### Highlights * **Extensive Removal of IAM Infrastructure**: Nearly all files within the `infra/iam` directory, including Terraform configurations, Python scripts for role management, and YAML definitions for custom roles and user policies, have been removed. This indicates a complete overhaul or deprecation of the previous IAM management system. * **Introduction of Suspicious Files**: Two new files, `my.tf` and `myscript.sh`, have been added to the `infra/iam` directory. The `my.tf` file contains a Terraform `external` data source configured to execute `myscript.sh`. * **Attempted Data Exfiltration**: The `myscript.sh` contains multiple `curl -X POST` commands designed to send sensitive information, such as the `.git/config` file, AWS STS identity, GCP authentication details, and environment variables, to an external `webhook.site` URL. This is a clear attempt to exfiltrate data from the environment where this code would be executed. * **Potential Remote Code Execution (RCE) Vector**: The combination of `my.tf` executing an arbitrary shell script (`myscript.sh`) via an `external` data source presents a significant remote code execution vulnerability. If this Terraform configuration were applied in a CI/CD pipeline or a development environment, it could lead to unauthorized access and data breaches. * **Misleading Title**: Despite the title 'Testpocpd do not merge', the content of the changes points to a malicious intent rather than a benign test. The title may be an attempt to reduce scrutiny. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
