Google Ads

Security checks for vulnerabilities and agentic risk

Overview

Google Ads changes require your approval, but automatic setup executes unverified downloaded code and may install additional agent skills.

Review and install a verified CLI release yourself before enabling this skill, including its effects on other agent skills. Understand that OOMOL mediates access to your connected Google Ads account, and review every proposed campaign change or customer-list upload. The remote installer and hosted implementation remain unverified; no malicious behavior was established.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The visible behavior is remote software installation rather than Google Ads management. Installing a dependency can be a supporting implementation detail, but the supplied chunk provides no evidence that this installer supports the declared functionality. The downloaded script's contents are unavailable, so its further behavior cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The fallback installation command executes a mutable network response directly in a shell without a pinned version or independent integrity verification; the PowerShell alternative has the same weakness. Compromise of the installation endpoint or delivery pipeline could execute arbitrary code with the invoking user's permissions, exposing local files and credentials. The missing-CLI prerequisite limits when this happens, and the declared oo-only tool allowance may block direct execution, but neither makes the documented installation method safe.

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.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.
