Finland

Security checks for vulnerabilities and agentic risk

Overview

This Finland travel-planning skill is a Markdown-only guide with disclosed local trip memory and no hidden execution, network use, or data exfiltration.

Before installing, be comfortable with the skill keeping a local Finland trip memory file under ~/finland/. Avoid storing highly sensitive details there unless needed, and review or delete that file when the trip is over.

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

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 75% 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.

## Border Reality - Finland is easy for standard air arrivals when documents are correct. - Overland border logic is less forgiving if the user assumes an eastern crossing is open without checking. - Ferry arrivals still require the same passport and Schengen discipline as other external-border routes when relevant. ## Common Problem Areas

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The skill explicitly creates and maintains a local memory file containing user travel preferences, constraints, and decision status, but provides no user-facing notice, consent flow, retention policy, or scope limitation. While the data is not extremely sensitive by default, it can still reveal personal travel plans, budget, mobility needs, dietary restrictions, and family details, creating unnecessary privacy and profiling risk if accessed by other local processes or future sessions.
