Domain Trust Check

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward URL reputation checker that sends user-provided URLs to Outtake's API, which fits its stated purpose.

Before installing, understand that any URL you ask it to check is sent to Outtake's service along with your API authentication. Avoid submitting password reset links, private documents, internal hostnames, or URLs with sensitive query parameters unless you are comfortable sharing them with that service.

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

Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Check up to 50 URLs in one request using `POST /trust/check-batch`:

```bash
curl -s -X POST https://app.outtake.ai/api/v1/trust/check-batch \
  -H "Authorization: Bearer $OUTTAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://link1.com", "https://link2.com"]}'

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Low
Confidence
87% confidence
Finding
The API reference instructs callers to send full URLs to a remote third-party service but does not warn that URLs may contain sensitive data such as query parameters, reset links, internal hostnames, or user identifiers. In a link-scanning skill, users may reasonably submit private or internal URLs, so the lack of a privacy notice or data-handling guidance creates a real information disclosure risk.
