Full Analysis
- [COMMAND_EXECUTION]: The Python scripts
scripts/agent.pyandscripts/process.pyutilize thesubprocessmodule to programmatically interact with thegcloudCLI. scripts/agent.pyexecutesgcloud auth print-access-tokento retrieve temporary authentication credentials for Google API requests.scripts/process.pyexecutes multiplegcloudcommands to list backend services, retrieve IAM policies, enumerate access levels, and analyze device compliance.- [INDIRECT_PROMPT_INJECTION]: The skill establishes an attack surface for indirect prompt injection by ingesting and processing metadata from external Google Cloud resources.
- Ingestion points: Data is pulled from GCP via
gcloudJSON outputs and HTTP responses fromgoogleapis.com, including resource names, user emails, and audit log entries. - Boundary markers: The scripts do not implement explicit delimiters or warnings to ignore instructions embedded within the ingested metadata when generating reports.
- Capability inventory: The tool chain includes local file-writing capabilities (
beyondcorp_report.json, text-based audit reports) and the ability to execute further CLI queries based on project and policy identifiers. - Sanitization: No specific filtering or escaping is applied to resource identifiers or log content before inclusion in output files, though the risk is localized to the generated reports.
