Security checks for vulnerabilities and agentic risk

Overview

This Google Ads skill is purpose-aligned and strongly gates sensitive account changes behind explicit user review and approval.

Install only if you intend to let an agent inspect your Google Ads account through an attached session or local API configuration. Treat any requested account change as business-impacting: review the displayed account, entity IDs, before/after values, timing, and rollback notes before approving.

A.I.G

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

- ask the user to paste a secret into chat;
- display a credential file;
- print environment-variable values;
- print a refresh or access token from an OAuth helper;
- commit a credential file or downloaded OAuth client secret;
- send a credential file through email, chat, or an artifact upload.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

1. **Attached browser** — Use for quick, user-visible inspection when the user has attached the intended logged-in Google Ads session.
2. **API** — Use for repeatable queries, larger result sets, or structured reporting when the Python client and local authentication are already configured.
3. **Neither** — Explain the two options. Do not ask the user to paste credentials into chat.
