Security audit
Google BigQuery
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed Google BigQuery integration that uses Maton authentication and includes clear approval and credential-handling safeguards for sensitive operations.
Install only if you intend to let Maton broker access to your Google BigQuery account. Use the narrowest OAuth scopes and connection possible, review every write/delete/query job before approval, and be especially careful with optional functions, triggers, and destinations because they can keep running or forwarding data until removed.
Vulnerability Patterns
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
- Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
